    1. 1. Mapping Without a Net Jeremy W. Crampton Georgia State University Global GIS Academy Presentation October 8, 2008 [email_address]
    2. 2. Without a Net? <ul><li>From the “sovereign map” to “people-powered” mapping: no authority net </li></ul><ul><li>Open source cartography/GIS: no proprietary net </li></ul><ul><li>Popular/amateur mapping: no credential net </li></ul><ul><li>Application in political activism/counter-mapping </li></ul><ul><li>Parallels emergence of blogs </li></ul><ul><li>Remaining challenges (net neutrality) </li></ul>
    3. 3. “ Geography is emerging as a fundamental principle for structuring the Web – a principle that yields the world’s knowledge through the lens of location. The strategy of adding location metadata to existing databases and accessing the vast amounts of information stored in these databases via geospatial services weds physical and virtual spaces, deepens our experiences of these spaces and incorporates them into our everyday lives .
    4. 4. Map mashups
    5. 5. Neogeography the Best Name? <ul><li>Field is new enough not to have a settled name </li></ul><ul><li>The geospatial web, geoweb, locative media, volunteered geographic information (VGI—Mike Goodchild), DigiPlace, and new spatial media </li></ul><ul><li>(Plus, domain name still available!) </li></ul>
    6. 6. What is the geoweb? Web-based georeferenced information… More than just maps online: – open access – map mashups – hyperlinked & interactive – distributed – 3D – virtual globes/digital earth – communities/crowdsource – bottom-up
    7. 7. In the process, [map amateurs] are reshaping the world of mapmaking and collectively creating a new kind of atlas that is likely to be both richer and messier than any other” The New York Times, 2007
    8. 8. “ It turns out that when we talk about the ‘world’s information’ we mean geography too” – Google
    9. 10. Remember to FOSS <ul><li>FOSS: Free and open source software </li></ul><ul><li>FOSS4G: for geography </li></ul><ul><li>4 components: </li></ul><ul><ul><li>Freedom to run any program </li></ul></ul><ul><ul><li>Freedom to modify the program </li></ul></ul><ul><ul><li>Freedom to distribute/sell/donate </li></ul></ul><ul><ul><li>Freedom to distribute modified copies </li></ul></ul><ul><li>Libre , not gratis </li></ul>
    10. 13. Don’t be evil
    11. 14. Increasing political participation with geospatial tools <ul><li>Are GIS/mapping following the experience of the netroots? </li></ul><ul><li>Not just maps of the news, but maps changing political participation </li></ul><ul><li>Alternative news sources </li></ul><ul><li>Micro-targeted political mapping </li></ul>
    12. 19. Voter turnout
    13. 20. Non-voters by household and race Atlanta, USA
    14. 25. In referring to the work of Foucault and post-Foucaultian social theory as the ‘new cartographer’ (along with the new archivist), Gilles Deleuze pointed to a mode of investigation and writing that sought, not to trace out representations of the real, but to construct mappings that refigure relations in ways that render alternative worlds. --UNC Counter-cartographies Collective
    15. 27. The “long tail” effect
    16. 29. Divided they blog?
    17. 30. Hotmap from Microsoft: shading indicates frequency of tile requests
    18. 31. Global internet connectivity (Chris Harrison/DIMES Project)
    19. 33. Traditional Big GIS: ESRI does geoweb? Jack Dangermond: “ GIS technology is evolving on the Web, making geographic knowledge easier to access and more…‘connected’ [with] new geographic information services and communities of users who incorporate these services into their daily decision making. Some have called this new environment the GeoWeb —a geospatial dimension of the cyberinfrastructure.”
    20. 34. … but still doesn’t get it? “ Jack Dangermond is skeptical…he worries that even the best-intentioned amateur could provide inaccurate data that could lead to a disaster. ‘Who wants to dig a hole and run into a pipe?’ Dangerman asks.” Computerworld , August 2007
    21. 35. Remaining challenges <ul><li>Digital divide: access to the “information economy” </li></ul><ul><li>Censorship/proprietary information </li></ul><ul><ul><li>OS vs. OpenStreetMap </li></ul></ul><ul><ul><li>Censorship in Morocco, China, India, Sweden, USA… </li></ul></ul><ul><li>Making crowdsource coherent (standards, GIS  geoweb, archipelagos of knowledge) </li></ul><ul><li>“ Net neutrality” </li></ul>
    22. 36. Conclusions <ul><li>The geoweb parallels rise of blogosphere </li></ul><ul><li>From top-down, controlled production of geospatial information </li></ul><ul><li>To bottom-up, crowdsource production </li></ul><ul><li>Open source: counter-mappings </li></ul><ul><li>Digital divide, net neutrality </li></ul>
