The Geospatial Web Feb16 V1 Mm The Geospatial Web Feb16 V1 Mm Presentation Transcript

  • Future of Geospatial Use & It's Changing Role in Citizen Engagement
  • Maps
    • Maps govern our understanding of the world in which we live
    • BUT this does not always mean they do this fairly.
    • As we have seen largely maps usage is defined by those with the tools to use them.
  • What are Maps for?
    • Maps are directive: they tell us where to go and how to get there
    • Maps are informative: Landmarks tell us what we may find in an area
    • Maps are aesthetic: they are a form of art used to express issues of perspective and presentation
  • Current approaches to mapping
    • Used to view and analyze information within a geographic perspective.
    • Overlay data
    • Perform spatial analysis
    • Zoom into areas of interest
  • Benefits
    • Well the layering of data allows for the easier management of data. (turn on/turn off data)‏
    • It's extremely accurate and so is the data that is viewed in a traditional GIS
  • Deltas
    • Largely the process for making a map is quite different from that of what we might have a mental model of.
    • Example: Traynor and Williams “ Why is GIS so hard to use? ” CHI '95
  • User Centered Mapping
    • Is the organization and utilization of of spatial data around the user's own spatial landscape.
    • Essentially we are seeing the integeration of PPGIS on the Internet as mashups
  • Map 2.0 Approach
    • Hockenberry er al. define this as the emergency of the API based web mapping applications that enables people to build their own maps.
    • These applications move away from the traditional application of web-gis that is more generalized.

  • Map 2.0 Approach
    • What this does is make the data relevant to the user.
    • Something that lacked in previous Web-GIS models built from desktop GIS applications.
  • Map 2.0 Approach
    • Similar to what we saw in O'Reilly's reading we see the exchange
    • Maps as a service as opposed to a package.
    • Architecture of Participation
    • Age of the Amateur
  • What does the future hold?
    • Tagging vs Attributes
    • User generated content
    • Ubiquitous technology and ubiquitous GIS
  • Neogeography
    • Geographical techniques and tools used for personal activities or for utilization by a non-expert group of users; not formal or analytical in nature.
  • It all about the user
  • New data formats
    • Allows users to create data that easily integrates with richer formats of information
    • This will create a Geoweb where geographic information is tied to abstract information - Geobrowsers
    • People can then search for things based on location instead of only keywords eg http://nearbynow.com/

  • Collaborative Mapping
    • A diverse commons of mapping data constantly updated by citizens, governments and the private sector
    • Data creation is following in the foot steps of Wikipedia and other social applications
  • Collaborative Mapping
    • Open Street Map - started in 2004, amateurs (in the best sense of the word), hobbyists and 'true believers'
    • 'The Success of Collaborative Mapping?' - a diverse commons of mapping data constantly updated by citizens, governments and the private sector
  • Ubiquitous Computing
    • As phones get smarter
      • Android
      • iPhone
      • Geospatial information becomes more important - searching by location is more valid
      • It also becomes easier to create Geospatial data
  • What about Citizen Engagement?
    • Traditionally, GIS is implemented as a tool for community involvement but it's application is largely derived by those experts building the application.
    • Largely the user is seen as a commodity to enrich the application with their data.
  • Citizen Engagement
    • Now it's becoming the role of citizen to not only participate but create the applications.
    • More and more the tools once held exclusive to the experts are being given to the user themselves.
    • What does this mean for the future?
  •  
  • What does the future hold?
    • More collaborative mapping
    • Data that is more relevant on a temporal level
    • Data that is more relevant on a location based level
    • Greater availability of spatial data in interoperable standards.
