  • The Geospatial Web Feb16 V1 Mm

    1. 1. Future of Geospatial Use & It's Changing Role in Citizen Engagement
    2. 2. Maps <ul><li>Maps govern our understanding of the world in which we live </li></ul><ul><li>BUT this does not always mean they do this fairly. </li></ul><ul><li>As we have seen largely maps usage is defined by those with the tools to use them. </li></ul>
    3. 3. What are Maps for? <ul><li>Maps are directive: they tell us where to go and how to get there </li></ul><ul><li>Maps are informative: Landmarks tell us what we may find in an area </li></ul><ul><li>Maps are aesthetic: they are a form of art used to express issues of perspective and presentation </li></ul>
    4. 4. Current approaches to mapping <ul><li>Used to view and analyze information within a geographic perspective. </li></ul><ul><li>Overlay data </li></ul><ul><li>Perform spatial analysis </li></ul><ul><li>Zoom into areas of interest </li></ul>
    5. 5. Benefits <ul><li>Well the layering of data allows for the easier management of data. (turn on/turn off data)‏ </li></ul><ul><li>It's extremely accurate and so is the data that is viewed in a traditional GIS </li></ul>
    6. 6. Deltas <ul><li>Largely the process for making a map is quite different from that of what we might have a mental model of. </li></ul><ul><li>Example: Traynor and Williams “ Why is GIS so hard to use? ” CHI '95 </li></ul>
    7. 7. User Centered Mapping <ul><li>Is the organization and utilization of of spatial data around the user's own spatial landscape. </li></ul><ul><li>Essentially we are seeing the integeration of PPGIS on the Internet as mashups </li></ul>
    8. 8. Map 2.0 Approach <ul><li>Hockenberry er al. define this as the emergency of the API based web mapping applications that enables people to build their own maps. </li></ul><ul><li>These applications move away from the traditional application of web-gis that is more generalized. </li></ul>
    9. 9. http://www.cityoforlando.net/gis/interactive_mapping.htm
    10. 10. http://www.gosee.ca/computerstores/
    11. 11. Map 2.0 Approach <ul><li>What this does is make the data relevant to the user. </li></ul><ul><li>Something that lacked in previous Web-GIS models built from desktop GIS applications. </li></ul>
    12. 12. Map 2.0 Approach <ul><li>Similar to what we saw in O'Reilly's reading we see the exchange </li></ul><ul><li>Maps as a service as opposed to a package. </li></ul><ul><li>Architecture of Participation </li></ul><ul><li>Age of the Amateur </li></ul>
    13. 13. What does the future hold? <ul><li>Tagging vs Attributes </li></ul><ul><li>User generated content </li></ul><ul><li>Ubiquitous technology and ubiquitous GIS </li></ul>
    14. 14. Neogeography <ul><li>Geographical techniques and tools used for personal activities or for utilization by a non-expert group of users; not formal or analytical in nature. </li></ul>
    15. 15. It all about the user
    16. 16. New data formats <ul><li>Allows users to create data that easily integrates with richer formats of information </li></ul><ul><li>This will create a Geoweb where geographic information is tied to abstract information - Geobrowsers </li></ul><ul><li>People can then search for things based on location instead of only keywords eg http://nearbynow.com/ </li></ul>
    17. 21. Collaborative Mapping <ul><li>A diverse commons of mapping data constantly updated by citizens, governments and the private sector </li></ul><ul><li>Data creation is following in the foot steps of Wikipedia and other social applications </li></ul>
    18. 22. Collaborative Mapping <ul><li>Open Street Map - started in 2004, amateurs (in the best sense of the word), hobbyists and 'true believers' </li></ul><ul><li>'The Success of Collaborative Mapping?' - a diverse commons of mapping data constantly updated by citizens, governments and the private sector </li></ul>
    19. 23. Ubiquitous Computing <ul><li>As phones get smarter </li></ul><ul><ul><li>Android </li></ul></ul><ul><ul><li>iPhone </li></ul></ul><ul><ul><li>Geospatial information becomes more important - searching by location is more valid </li></ul></ul><ul><ul><li>It also becomes easier to create Geospatial data </li></ul></ul>
    20. 24. What about Citizen Engagement? <ul><li>Traditionally, GIS is implemented as a tool for community involvement but it's application is largely derived by those experts building the application. </li></ul><ul><li>Largely the user is seen as a commodity to enrich the application with their data. </li></ul>
    21. 25. Citizen Engagement <ul><li>Now it's becoming the role of citizen to not only participate but create the applications. </li></ul><ul><li>More and more the tools once held exclusive to the experts are being given to the user themselves. </li></ul><ul><li>What does this mean for the future? </li></ul>
    22. 27. What does the future hold? <ul><li>More collaborative mapping </li></ul><ul><li>Data that is more relevant on a temporal level </li></ul><ul><li>Data that is more relevant on a location based level </li></ul><ul><li>Greater availability of spatial data in interoperable standards. </li></ul>
