Google Maps has been an incredible service in the past years. Not only it was Google’s engineers, who invented the slippy map, which revolutionized digital maps, but its approach to offer such a service for free and shock competitors with a free routing service. Google has a tremendous overview on all activities on the Internet; billions of search queries everyday say a lot about people’s personalities. With analytics in websites, Google tracks people’s paths from one page to the next.

We are just at the beginning of this massive data collection endavour. TomTom now throws out their gadgets for free just to get real-data from their users. Ironically, it came out recently that they sold the real-time traffic data to the Dutch police. That kind of data collection is not appreciated, all other data collection is agreed on with a small click by accepting the terms of service.

The author Daniel Suarez is worried about the future with his new book: “Understanding the Daemon.” It is still fiction, but that can change soon: “Computers have learnt from us with every Google search, with every „I like“-click. Now they are beginning to change us“. Every time we click, we feed the system called Internet and the outcome is not yet known. Ironically, the features of web 2.0 have incredibly helped to feed the system. Each recommendation, rating, each link, makes the data analysis better. But I am really worried that this is not always for the better. The open available data sets are peanuts compared to data sets of Google or Facebook likes. The question is also what data shall or can be public?

Data becomes more important than hardware. Apple is so eager to collect data that they spy on iPhone users activities and obliged users to do so over their terms of services. I have read a nice comparison: It is like buying a car and you are obliged to not use the seat belt. But things are not for free, although many services draw that illusion. Companies will at one point need to earn money with these adventures.

That’s why Google Maps has changed their terms recently. Websites, which use Google Maps are from now on obliged to “forward display any advertising delivered in the maps imagery“. An obvious and, from a company perspective, understandable move. Perhaps Google will invade millions of pages with advertisement soon. I am sure it is only a matter of time when these companies start to make money with personal data.

That’s why projects like Openstreetmaps are so important because there is an attempt to offer valuable geo data without restrictions. There is an uneven race for getting data open for more transparency and, for example, for better citizen services. Recently, companies, such as Nike, have started to provide open data. However, I get the sense it is just a public relation move; or will they soon provide data up and down the supply chain, so one can follow up how sneakers are being produced? The crowdsourcing potential for such open and free data will keep growing if more and more people join the process. However, these type of data collection is tiny compared to the huge commercial data sets. Ironically, commercial companies now “exploit” Openstreetmap data because it is so good.

That is one big reasons why I co-founded the Open Knowledge Foundation Germany two months ago – to work more on transparency projects.

Digital cartography has made map making a lot easier. But If a map contains a lot of data or specific data, it can become a complex or costly adventure. Despite the efforts around open data, still the majority of data is not publicly available, and if so only for high costs. Crowdsourcing is one alternative to collect data for maptivism, but maybe some of these approaches will not soon be needed if automated mapping is further progressing.

Automated mapping

It is quite impressive and a bit scary to see the pace of innovation around digital recognition. Its aim is to make more information available from the offline world. Google is on the frontrun of digital recognition with another example: 3D trees in Google Earth. Google has chosen parks in 50 cities around the world to identify in an automated process trees out of satellite images.

“With 3D trees in Google Earth, we’ve brought characteristic trees to life, from the palm trees that dot San Francisco’s bayfront Embarcadero Street, to the olive trees that cling to the Acropolis in Athens, to the flowering dogwoods found in Tokyo’s parks. All told, there are around 50 different tree species to explore in Google Earth and counting!”

Consequences for mapping

A while ago I blogged about the crowdsourcing Urban Forest Map in San Francisco. Its goal is to map all trees in the city. Now at least the work for the park is not needed anymore if Google is giving out the data. Thousands of people from the Openstreetmap community use satellite imagery from Yahoo to draw shapes of buildings into maps. Is that becoming obsolete soon? What needs to be manually mapped? Of course a lot, because most of such data will not necessarily be publicly available. One example is real-time data. Check this post on maptivism: live tactical mapping for protest swarming.

Here, we are also getting in a dilemma. Such a virtualization of trees can contribute to the protection of forests. Imagine the mapping happens within days and deforestation in the rain forest can be act on quickly. However, what else can be mapped? If trees can be classified, all kind of objects can be classified if digital recognition software becomes increasingly powerful. Check for example the bird’s eye view from Bing, where you can see detailed aerial imagery (see image), not to mention Google street view.

If you sit in front a long list of information, it is often difficult to make quickly sense of it. If you look at a map of the same data, you might get a picture of it rather quickly.

1,470,000 US gallons of oil were leaking from an oil pipe of British Petrol in the Gulf of Mexico everyday. What does that tell you? When you look at this map from ifitweremyhome.com, then you get a better sense of it. The oil spill size was as big as Southern UK.

ifitweremyhome.com

If you do have some data, you can start working with a new great tool called openheatmap.com, however if not, then you need to collect it yourself.  One way is done by the grassrootmapping.org project, which has done a great initiative to document the oil spill on the coast line. Another one is the Oil Reporter from the Crisis Commons group. You “only” need an Iphone or Android driven phone and you can get the app to report where oil is found.

urbanforestmap.org

Context is king and therefore some other projects want you to share information to find out more about your environment. One example is the Urban Forest Map project: “The Urban Forest Map is a collaboration of government, nonprofits, businesses and you to build an inventory of San Francisco’s urban forest.” Citizens create an inventory of trees in their city and get exact information about the ecological impact.

Another mapping & crowdsourcing project is a research project, which founds to create a location based happiness index. Through an application, volunters are asked throughout the day about their mood and that information plus the location is then collected. Mappiness shall help to understand “how people’s feelings are affected by features of their current environment—things like air pollution, noise, and green spaces.”

A similar project called Mapumental, done by Mysociety. Watch the video for that amazing idea.

In Germany a similar project, called Mapnificient, has been done. At the moment we try to implement the same for Create Frankfurt.

A while ago I was asked, by Markus Beckedahl, to present something on maptivism at the re-publica conference.  And even though I am still exploring this new field, I tried to give an overview of the fascinating world of maptivism.

Here is a video of my presentation (33 min.), which also shows the slides I have included below. The first two minutes are in German (in the beginning I forgot I wanted to held the presentation in English in the first place). The presentation covers a lot of what I have been blogging about here and there, but I also included some other great examples. The re-publica took place this year and, thanks to the organizer,  a lot more international and inspiring people got together in Berlin. It was great discussing digital activism with Sokari Enkine, Sam Ben Gharbia, David Sasaki, Rolf Kleef and Tobias Eigen.

In this blog post, I will dive into the latest buzz: Google Buzz.

Google Buzz is a huge jump in location-based services as it happens all around the world at once. I have browsed through the map of Google Buzz’ mobile phone version, where statuses can be combined with your location – it is striking to see where all information pops up. Here are maps of three different cities – Johannesburg, Cairo and Mumbai – showing messages from the last 24 hours.

“But the maps provided something that the narrative and statistics lacked [...] We could articulate the case in words. [...] But when you’d put up the maps, they’d stop listening to you and look at them [as if to] say, ‘Is this really possible?’” Reed Colfax in an interview by Bob Burtman (water distribution example below)

There are a growing number of cases of Maptivism (Maps + Activism) around the world. I wrote about the great potential for engagement and transparency before. Although it is not a new method, it is certainly still quite different from the old school maps – because of the easiness to use digital maps. There are also more and more tools offered to either get geodata or to use existing data to visualize it more easily. GeoCommons is one such service for open geospatial data.

Western Africa

The West Africa Trade Hub, a USAID funded project did an interesting project. They questioned truck drivers in Western Africa about their experiences with checkpoints. The results were long delays and high bribes at region’s worst checkpoints (mapped below). A recent interview I did with Mark Davies indicated also some interesting insights from African trade and the potentials of social networks.

China

The China Real Time blog has highlighted an initiative by the Chinese blogger Guo Baofeng for a China Pollution Map:

“The chart (developed on Google Maps) allows viewers to mark spots associated with high levels of pollution or incidents of contamination, based on publicly available information. Since it was open for public participation last week, the number of views has more than doubled to about 5,000 compared to a week earlier, when it was first displayed online.”

Due to the recent move of Google to re-think its engagement in China, hopefully this map will not be censored any time soon.

Brazil

Mapping can be particularly helpful for community development. Corinne Ramey reports form a project to map slums in Brazil through mobile phones. “By uploading information to the phones, the reporters are mapping the unmapped, one road and cafe at a time.” Once places are mapped they can be used for multiple purposes

Kenya

A similar, but more extensive project has happened in the biggest informal area in Nairobi: Kibera. A team of mappers trained cohabitants of Kibera to map the largest slum in Africa.

OpenStreetMap

Some of you probably know that I am particularly amazed about the OpenstreetMap project. Often, people ask me why we need such an open map, if we already have Google or Yahoo maps? Because it is not only about maps, but more importantly, about what we map and that we can use the data freely to use it the way it is needed. Or as Mikel Maron nicely puts it:”But the point is that with open source and open data, people everywhere don’t have to wait for Santa Google to gift them with new features ..”

When do you start mapping?

Mapping is really easy. I walk around in Mexico these days, during my free time and map streets and buildings with a GPS enabled mobile phone – a cheap GPS device is enough and costs under 100 Euro. That way you can already participate in tracking streets worldwide and upload them to OpenStreetMaps. Here is more information on how to participate.

Lastly, there is a great initiative by the tactical tech collective called Ten Tactics: “Exploring how rights advocates use information and digital technology to create positive change.”

Location, mobile phones and the Internet, combined together, are becoming an attractive amalgam for new opportunities. There is a fascinating trend to see the convergence of mobile technologies connected to the Internet and the rising importance of location. This is not just another hype, but could really be interesting for the non-profit arena.

I have already written about the potential renaissance of the Internet of Things – how low-cost technology can be used for better transparency. In a recent paper Tim O’Reilly calls it the information shadow, which simply means “offline” things and their information are increasingly connected to the web. “All of these breakthroughs are reflections of the fact – noted by Mike Kuniavsky of ThingM – that real world objects have “information shadows” in cyberspace.”

At the recent KM4DEV conference, I tried to summarize my thoughts on these developments and their potential implications on development work and activism. I have uploaded the presentation, which is hopefully as self-explanatory as possible and, in this blog post, I would like to add some more remarks:

My initial attempt for the presentation was my reflections on “what would happen if the Internet becomes locational aware? What are the implications of the boost in geo-data? And, what are the consequences of the ubiquitousness of mobile phones?”

Presentation

I start with two interesting quotes:

“It is estimated that as much as 80% of data contains geo-referenced information.” (Liping Di)

“It is not about mobile any more. It is the convergence from the social web with the mobile. The mobile let you interact within a network in a highly contextual way.” (Teemu Arina)

A jump to Uganda, where Google, Grameen, MTN and Brosdi have established an SMS service for health and agriculture tips. It has attracted over a million in the first months. I have heard that it was free in the beginning and maybe that was also a reason for such high use. Interestingly Google needed local institutions to get the content as it is not as easy to collect in the African context. For example, statistical data is not widely collected and, in particular, local content rarely digitalized. That might be a reason why Google has sponsored the Kiswahili Wikipedia Challenge.

Citizen journalism (action) from anywhere

The famous initiative around the mobile African reporters is just one way to use the mobile phone and report from everywhere. “Fix my Street” in Great Britain shows how citizens can report on street damages through their mobile phones and emails are send to public institutions. “Stop stockouts,” a recent project running with the Ushahidi software, allows citizens to report medical stockouts in pharamcies, which are obliged by law for a certain stock in Southern African countries. I have wondered for a while how these efforts can help to monitor and evaluate development projects in a different way?

What makes digital maps different?

I was recently invited to moderate an online dialogue on human rights and geo-mapping. It is fascinating to see how mapping can help to advocate human rights and also empower local communities to share their environment. One such project is Green Maps with projects all around the world or a Google Earth project with indigenous communities in the Amazon. Maps can reflect different perspectives, interests, constraints and demands for change. What are the implications of people worldwide mapping their environment and having access to these in any place through their mobile phone?

To get a further understanding of digital maps, we need to forget about the usual paper maps with typical street information. Digital maps can offer all kinds of information, but different to paper maps, they have all the underlying geo-data, which can be used in many other contexts.
There are countless things that can be mapped and might help others in the local context:

• Surveillance cameras in my neighborhood
• Accessibility of facilities
• Bike tracks in my city, etc.
• Environmental pollution
• Cheapest shoe stores

So we have:

1. Increasing geo-data available
2. Access to these data through maps or other applications on mobile phones wherever we are, and
3. Increasing contributions to this information base.

Such efforts can lead to all sorts of services such as the traffic information or to find public bus connections in Chennai, India, for instance, which I highlighted in my post on Maptivism.

Explosion of location-based services

There is an “explosion” in location-based services these days, and all big players have been buying map services. Apple has just bought a mapping company and Google has announced that they will offer free navigation services for Android phones.

The geospatial web

In recent years we have been able to see huge efforts to offer maps and geo-data. Big names such as Google, Yahoo and Microsoft offer maps. OpenStreetMaps offers the geo-data behind it even for free because it is a worldwide voluntarily run project. Although Google has done some remarkable efforts to offer maps also in developing countries, I believe it is very important that such maps and the data behind them are a public good. A nice example is Kabul, which is only accurately mapped through the voluntarily run OpenStreetMap, and it is much better.

The geospatial web for development work

It is striking to see that so many development organizations seem to be sleeping when one looks at the potential for geo-referenced information. The World Bank is heading in this direction and the humanitarian and relief sector is doing a lot, as the recent crisis mapping conference showed. But many development organizations are still overwhelmed to offer their data in universal standards such as RSS or offer Application Progamming Interfaces to mix data.

We are struggling daily for better filters, particularly in development organization, but location could be a decisive third filter:
Information

• Filter 1: Topic
• Filter 2: Person
• Filter 3: Location

I finish with a great image by Andrew Turner, who has an inspiring, albeit rather technical presentation about the geospatial web. From global to local – lets get the Internet location aware.

It is estimated as much as 80% of data contains geo-referenced information. So, a lot of information can be displayed through maps. Digital maps allow easy ways to present large amounts of data and reduce complexity. Activists have found creative ways to use maps, but also development organizations have to deal with a lot of spatial information. Using geo-referenced through maps can improve transparency, and yet not so many organizations use it.

Difference of digital maps
Digital maps have brought three major changes.

1. Digital maps, in contrast to paper maps, can be combined with all kinds of data even in real time.
2. Nowadays, everybody can access huge data from the public domain and combine these with maps.
3. Citizen maps are created through voluntarily worldwide effort and participation, are freely available and offer new ways for transparency.

The Tactical Tech Collective has a great guide for beginners and comes up with a good description of why maps are so helpful:

“Advocacy organisations worldwide face great challenges. One of these is how best to communicate and disseminate information to communities, staff, founders, governments and other organisations in a world saturated with information, media and advertising. They may also need to keep track of complex and diverse information in their own work.”

By the way, there was also an interesting online forum by New Tactics on ‘information activism’ with many examples and exciting discussions.

But why are make maps so different?
Anders Peders has come up with some simple points in his presentation “Geomapping Making Invisible Data Visible”:

• Recognition: Ooh that’s the place we are talking about!
• A feeling of connection: It’s around the corner!
• Connecting the dots (topics) on complex issues.
• Engagement: This has to change! I want to help out.

Maps for activism and campaigning
Maps have a long history and since the early days maps have been used for many purposes, such as to show changes through bygone times and to manipulate them for propaganda. But never before it has been so easy for individuals and groups to use maps for own purposes. The Economist goes a step further and writes “mapping technology has matured into a tool for social justice.”

There are various projects using maps worldwide and here are a few examples:

Green Map System has engaged communities worldwide to map green living (nature and cultural resources). In one case, a map was created for the environmental hazards and challenges in the greater Banjul area in Gambia. Other maps from Europe are already interactive.

“Eight Maps” has been mapping people in San Fransisco, who donate for a campaign against a law that supports sex marriage, trying this way to put them on the spot. This example also shows how far such campaign might go into privacy issues.

Another great example comes from Worldmapper:

Ecological footprint of each country in the world

Another nice, albeit printed map series, is an Atlas of Radical Cartography, “a collection of 10 maps and 10 essays about social issues from globalization to garbage; surveillance to extraordinary rendition; statelessness to visibility; deportation to migration.” My favorite map is of the only walking track left in Manhatten, where you are not followed by surveillance cameras.

One key role will be played by the OpenstreetMap project. Other than Google Maps, it offers all geocoded information for free and is, equally to Wikipedia, an open project. I am working these days on a local politics project for transparency. The richness of geodata was astonishing and very helpful. It all started with the city of London and is now a worldwide movement. I went to the annual State of the Map conference in Amsterdam, learnt a lot about mapping and filmed some interviews. It was great to meet finally Mikel Maron, foundation member of OpenStreetMaps, who gives fascinating examples of how open maps benefit people living in informal areas in India.

Fredy Rivera from Colombia describes the dangerous work of mapping in Colombia and how they plan to provide better geodata to indigenous groups in the rising competition around water resources.

Arun Ganesh has done some incredible mapping efforts for the city of Chennai in cooperation with the local administration. He even went a step further and build a great website to find public bus connections and organized the printing of maps to post them on local bus stations.

Imagine we do not only use our mobile phones to make phones calls and SMS, but to contribute to science. How does that work? We can directly engage in micro-voluntarism or contribute valuable information without doing much more than carrying our mobile phone with us. Just as volunteers share computer processing power or look out for new galaxies, so can mobile phones become tools that collect valuable data.

Cairo traffic jam by tronics on flickr (CC)

How does that work?

Newest mobiles phones have global position system (GPS), which shows on a map where you are at the moment. Google and TomTom have developed – independently from each other – an initiative to use location-based data to gather real time traffic information. It is quite simple and genial. GPS can determine whether you move fast or slow, so if you are probably in a car or walking.  So, if feedbacks are sent from an area of slow or non movement where the map indicates a highway, then it is much likely that there is a traffic jam.

The Swiss datenvisualization.ch blog has a nice image to show how it works. (By the way a great resource!)

Location services through all devices

By the way Google offers location position system also for non-GPS enabled phones and browsers (Firefox). How? They have a huge database of mobile tower locations. Computers have an IP address, and a wifi access point delivers another proximity. A bit scary if you think of privacy.

Mobile phones sensors

But that is just the beginning. Nokia has developed a mobile phone with sensors to gather results from your environment, such as noise level, pollution, personal health, weather monitoring, etc. Scientists from MIT call it “Reality Mining” and “provide insight into the dynamics of both individual and group behavior.” The Economist has an interesting article called Mobile Phones: Sensors and Sensitivity.

“Eric Paulos, a computer scientist at Carnegie Mellon University in Pittsburgh, predicts the rise of “citizen scientists” able to measure and sample their surroundings wherever they go. He foresees amateur experts being driven by a new sense of volunteerism,… Dr Paulos has already equipped street sweepers in San Francisco and taxis in Accra, the capital of Ghana, with sensors to measure pollution levels, which he then used to create a map of each city’s environmental landscape. He plans to do the same with cyclists in Pittsburgh.“

This information can then be offered again for mobile phone users through applications with augmented reality, the latest hype around mobile phones. Tim Boucher has post, where he outlines a critical way augmented reality can lead to:

Privacy and surveillance

The flip side of the coin is privacy and potentially larger surveillance of citizens. Iphone owners already can get a taste of it. Pinch Media Spyware can be implemented by any Iphone-application-developer and can send your location and much more to the developer. Potentially, a programmer can develop profiles of movements. As long as a mobile is not really turned off, it continuously sends information and therefore can be located. In countries with authoritarian governments one can imagine, how easy it is to monitor exactly where dissidents are moving if they do not protect themselves.

Technology driven volunteerism?

Step by step mobile phones develop to a much broader instrument. It can help to valuable data for development such as another project described in the Economist article:  “A good example is the study of well-water contamination in Bangladesh conducted by Andrew Gelman, a statistician at Columbia University. His project combined readings from remote water-sensors with queries and data which villagers keyed into their mobile phones.“

In particular in development projects a sufficient data base is often not giving. Ushahidi has shown the potential for mobile crowdsourcing. Eric Paulos “foresees amateur experts being driven by a new sense of volunteerism, the 21st-century equivalent of cleaning up the neighbourhood park.” However, it has to secure that this information guarantee privacy and are a free public good.

I started blogging at the Web2fordev gateway, from which I will crosspost some articles here from time to time to get some further discussions on web2fordev. I wrote the following piece together with Giacomo Rambaldi, the initiator of PPgis (Open Forum on Participatory Geographic Information Systems and Technologies).

Online Mapping for Development: Opportunities and Challenges

Maps are an effective medium which can be used for development projects. They help visualise the spatial distribution of complex problems their inter-relationships and promote awareness. In recent years the availability of free or low-cost digital maps and remote sensed images has unleashed unprecedented ways to make use of spatial information for a variety of purposes. Last week we analysed the potential of open data sources for development. Open maps are an excellent example illustrating the many ways to use and link information in creative ways. In almost any development project, maps can assist in the interpretation of spatial issues, foster awareness and support transparency. Le Monde Diplomatique, offers interesting examples on using maps to visualize complex conflict situations. Unfortunately in developing countries large scale maps are not always easy to obtain, data are often outdated or inaccurate or too expensive. Free digital maps offer an alternative.
Potentials and Opportunities

Here are a few examples:

• The Harvard university runs the AfricaMap project, where one can view the African continent through different data layers. It is a good place to experiment a bit. For example in turning layers on and off for display and adjusting their transparency allows users to superimpose data sets. Resulting thematic maps can be linked from other sites. .

• Back at the 2007 Web2forDev International Conference Paul Saunby presented some great simulations on maps using open data around the issue of climate change. That way he could simulate future forecasts for a specific coast. “Such maps could provide planners with valuable information on where to build new roads or houses. They could also give farmers a better idea of where to plant next season’s crops or how best to irrigate their fields.”

• UNEP offers the Atlas of the Changing Environment: “Through illustrations, satellite images, ground photographs and powered by Google Maps, this interactive media depicts and describes humanity’s past and present impact on the environment.”

• A renouned example for putting maps to work is Ushahidi which means “testimony” in Swahili, where human rights activists offers a platform that crowdsources crisis information. It allows anyone to submit information through text messaging using a mobile phone, email or web form. Resulting data are visualised on thematic maps. Recent initiatives covered the Swine Flu Epidemic and the elections in India. The same free and open source application has been used to spatially document the Gaza war and Eastern Congo conflict.

• The AGCommons project combines mapping with mobile phones and aims to equip “Africa’s farmers with location-specific information to reduce uncertainty and increase returns”. AGCommons was one of the organizers behind the WhereCamp in Nairobi, entirely devoted to mapping.

• Another ambitious project is done by scientists from the International Center for Tropical Agriculture (CIAT), who want to create the first detailed digital soil map of sub-Saharan Africa. “African soils are among the poorest in the world, and many farmers suffer from chronically low-yielding crops. With accurate soil maps, we find farmers can increase their yields by around 60%, and sometimes double.” (BBC)

But whoever plans to make use of online maps in Africa should have a look at Google maps and Open Street Maps. Both services offer already some impressive maps for some parts of Africa. Google Maps introduced lately a massive update of maps for Western Africa and Open Street Maps (OSM) added more then hundred thousand miles of roads lately.

Google Maps acquires map material and offers to combine it with third party data and on your own website. Open Street Maps goes a step further offers its complete data with all geo reference for free under the creative commons license. The license is currently changed to a an Open Database License Agreement. OSM relies completely on volunteer work. Thousand of GPS equipped mapers go through streets or parks worldwide and contribute to maps. The result are impressive and in some place the same as good as Google maps or even better. Check out how Mikel Maron initiated some detail mapping for Palestine.

Aidworker shows how OSM maps are even much better in developing countries on the example of Kabul and Tiblis. So in the case of OSM you can download entire geodata, whereas in Google you somehow are bind to their digital maps, which allow impressive presentations.

Challenges

There are undoubtedly also some challenges. In the context only some parts and mainly urban areas have been mapped and there is a need for a critical mass of mappers to enter and cross-validate data in order to achieve a satisfactory degree of accuracy. The dilemma is that where maps are needed most, not enough volunteers are available and in other countries such as in Europe, maps have been developed the furthest. The transparency of maps can also be used for critical issues and lead to discrimination as the Times report from Japan.

Nevertheless digital maps have catapulted cartography into new dimensions in recent years. As a most information is location-specific, mapping offers great opportunities to support communication in development. In the past mapmaking was the realm of a few. Today mapmaking has become a widespread activity accessible to experts and non-experts, well minded and otherwise. Collaborative mapmaking offers great opportunities for development organizations to share and collect data.

Words of Caution

Said that a few words of caution are necessary: Users of online mapping facilities should have a close look at the terms of service they sign up before submitting their contributions. In the case of Google Map Maker upon submission of the data, the service provider acquires “perpetual, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display, distribute, and create derivative works.

Further, the frenzy of geo-tagging and online publishing of images, videos and other type of information without obtaining prior informed consent from the concerned parties may result in the infringement of privacy and intellectual property rights. With Open Street Maps in the old and new license, the contributed data is free for reuse and can be used for commercial purposes as well.

At WhereCampAfrica, a gathering which brought together geographers, cartographers and mobile mapping specialists to discuss the potential – and difficulties – of the ‘geographic web’ in Africa, participants expressed their concern that indiscriminate online mapping could feed tensions over land ownership and resource use and control (BBC).

The Inportance of Good Practice

In times where online mapmaking has reached exponential growth rates, there is the need to be increasingly aware of the implications and impact of making geo-located information publicly available and on the need to adhere to the ethical principles of privacy, confidentiality, of obtaining prior informed consent and avoiding exposing knowledge holders at risk.  Practical ethics in the context of participatory mapmaking are discussed on an article published on Participatory Learning and Action (PLA) in 2006. The article is available in 12 languages.

The other day I stumbled over this news piece: “The phone that feels the flu before you do” – a company offers a service, where one can find out how intensive the level of flu is in their area. So, basically, you can get “Open Source Intelligence” via mobile phone. I find this quite fascinating because of the potential it entails for other usages and it also says a lot about the future power of information.

Different to older times when you went to your PC to search for information such as a definition on Wikipedia, in the future you can access it anywhere, and you also: a) get real time information about what happens around you and b) you get to participate collectively to refine information, for example through mobile crisis mapping. So imagine mobile phone users engaging in such a collective information gathering for all kinds of purposes. But who will own the information and could it be guaranteed to be open and reliable?

In the case of the flu alert, the company “will say, for instance, that 8 percent to 14 percent of the people in your ZIP code have respiratory illnesses, representing a “Moderate” risk level.” Personally, it would not influence my decision to leave the house or not. To me, the case of the flu alert highlights the potential to use such services for other purposes also in other areas.  I find the use of widely available valuable information for the public very interesting. All sorts of available intelligence is broad to you on your mobile phone. So is the case of fixmystreet.com, from which I can report damages in my neighbourhood and report it to the responsible person; or I can check product information through a common source written by consumers in the supermarket. More importantly, I could have access to environmental data on the corner I am standing at? I can foresee a lot of potential, but also I am worried about locked information, no clarity of ownership and too little access to information.

In the flu alert example, the company “gets the information on disease levels from Surveillance Data Inc. — which gets its data from polling health care providers and pharmacies.” It sounds almost as a mashup, where you combine different data sources. I imagine the future lies in combining intelligently different open available data resources, for example through RSS/feeds or API to provide open intelligence.  Such steps are some interesting startups around climate change, which offer API (Application Programming Interface) for different sorts of environmental data – it simply means, that you can use their data for your own purposes or services and combine different data streams. For example, the World Bank offers “114 indicators from key data sources and 12,000 development photos” and AMEE, the climate change startup,  offers an “open platform for measuring the energy consumption of everything” (Check www.openeco.org/ for more on sharing data to measure climate change).

Google found a much easier way to publish the flu intensity in an area by simply analyzing and mapping search request for flu related issues. So Google will not only make revenue by advertisement, but through offering various of these kinds of services in the future. But frankly, I am a bit concerned about it since a lot of information resides within companies and it is in many cases not publicly available or cannot be used by nonprofits. In the case of Google, the potential to analyze society behaviour is unlimited. If they focus, for example, on the local level, all kinds of patterns and differences can be found out (e.g. politics, consumerism or health).  It seems to me that the future asset will be this sort of information power. The challenge can be easily seen when you compare OpenstreetMap and Google maps for the cities of Kabul, Afghanistan (Google – Openstreetmap) and Luanda, Angola (Google – Openstreetmap). In both cases the open source approach for maps offers better maps done by volunteers. (Thanks to aidworkerdaily.com for the inspiration!)

I think we have just started to tap on the potential of these rich resources, but also will need a lot of further discussion on what type of information needs to be openly available.
