      • GIS 2.0: Definition, Implications for Humanitarian Information Management, Disruptive Strategy for Implementation
    • Built the Cyberinfrastructure system at KARS/KBS
      • 4 th year of the project
      • Web mapping core, metadata portal, dynamic HTML redesign
    • Humanitarian Intelligence Analyst
      • Humanitarian Information Unit (HIU), U.S. Department of State
  • 3. NeoGeography
    • Does it really exist?
    • Began as an expression of Web 2.0 applied to maps
      • AJAX, JavaScript APIs, RSS
      • Craigslist mashup / Chicago Crime Maps *
    • Democratization of geographic tools
    • Web Developers discovered Geography…
    • What about Geographers discovering the Web?
  • 4. What is Web 2.0?
    • “ a transformative force that’s compelling companies across all industries towards a new way of doing business characterized by harnessing collective intelligence , openness , and network effects ”
      • --Tim O’Reilly
  • 5. What is a GIS?
    • A digital representation of the earth, structured to support analysis (Dobson, 2007)
        • Automated systems for the collection , storage , retrieval , analysis , and display of spatial data (Clarke, 1995)
      • Should also include dissemination
    • Composed on software, hardware, and people
  • 6. GIS 2.0: A Reformulation
    • Free and Open Source Software
    • Web 2.0 philosophy
      • collective intelligence, network effects, openness
      • Internet as a platform
    • Open Standards
      • Interoperability
  • 7. GIS 2.0: A Reformulation
    • Ubiquitous communication
      • Widespread wired and wireless networks (voice and data)
    • Device convergence
      • Mobile devices increasing in power and functionality
      • Phone, camera, GPS, form-based database input, cellular, wifi
    • Cloud computing
      • SaaS, PaaS, IaaS

  • 20. GIS 2.0: Dissemination
    • Multiple tiers of users
    • Web mapping applications
    • .
    • GeoCommons Finder!
  • 21. Geography 911 Project
    • Goal: Design and implement a neogeography application that allows users to access, input, and modify spatially relevant data on a map of the University of Kansas Lawrence campus.
    • Scope: ... provides to the community the means to share geotagged content and geographic data from multiple locations in multiple formats on the internet.
      • Content and data can be uploaded into or embedded on individual layers then be displayed on a map of the Lawrence campus.
      • Examples of content may include photos, videos, text comments, vector-style locations (such as routes and “push-pins”), or user information
  • 22. Project Architecture (Input)
      • How do people get data into the system?
    • Data Collection
      • On-screen digitize, SMS, email, forms
      • How to capture existing authoritative data?
        • RSS, geocode
    • Storage / Retrieval
      • Leverage geographic nature of data requires spatial data types
      • PostGIS::ArcSDE
  • 23. Project Architecture (Output)
    • Once data is in the system, how do people interact with the information?
    • Visualize
      • Web Map Server (GeoServer, MapServer::ArcGIS Server)
        • Styling (SLD, MAP files::ArcMap)
      • Map Window (OpenLayers: :ESRI JavaScript or Flex, Google)
      • Widgets (GeoExt::ESRI JavaScript (Dojo) or Flex)
        • (Layers, Queries, Analysis, Draw tools…)
      • Base Layer Data (Open Street Map::ESRI, Google, Microsoft)
    • Storage / Retrieval
      • SQL statements for user queries
      • Spatial analysis functions intrinsic to spatial database
  • 24. Project Architecture (Output)
    • Once data is in the system, how do people interact with the information?
    • Disseminate
      • Publish data in a several different formats
      • Web Services (OGC), KML, CSV, text….
      • RSS, SMS, email updates
