      • Humanitarian Intelligence Analyst
        • Humanitarian Information Unit (HIU), U.S. Department of State
    • 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?
    • 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
    • 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
    • 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
    • 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
        • Network-driven commoditization of IT

    • GIS 2.0: Dissemination
      • Multiple tiers of users
      • Web mapping applications
      • .
      • GeoCommons Finder!
    • 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
    • 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
    • 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
    • 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
