  • Advancing Open Source Geospatial Software for the DoD/IC MILITARY OPEN SOURCE SOFTWARE (Mil-OSS) August 3, 2010
  • Summary
    • Many DoD/Intel organizations deploy geo web services based on OS software
    • Increasingly organizations turn to OpenGeo
      • To deploy with greater ease and lower risk
      • To develop advanced features
    • OpenGeo is extending the OpenGeo Suite for collaboration and Web 2.0 functionality
  • OpenGeo Background
    • Founded 2003. HQ New York City
    • Enterprise support for a complete, open-source web mapping platform
      • Certified, stable releases with one easy install
      • Professional support and service
      • Training
      • Advanced development & feature enhancements
  • OpenGeo Suite Bundles Five Open Source Projects For Enterprise Use
    • Storage: PostGIS PostgreSQL spatial database
    • Application server: GeoServer map/feature server
    • Application cache: GeoWebCache tile cache
    • User interface framework: GeoExt / ExtJS
    • User interface map component: OpenLayers
  • Strong OGC Standards Support
    • WFS Reference Implementation
    • WFS, WFS-T 1.0
    • WFS, WFS-T and WFS Xlink 1.1
    • WCS 1.0 compliant and 1.1 Reference Implementation
    • WMS 1.1.1 and full SLD
    • SLD is native style format
    • KML with Super Overlays
    • GeoRSS, GeoJSON, Shapefile, PDF, WMS-C, CSV, XLS
  • KML Super Overlays
    • Problem: Display large data sets on Google Earth
    • Generated KML is simply too big
    • Features for display have a clear hierarchy
    • Zoomed out, you want to display only the most important ones
      • Less important ones should appear progressively, as you zoom in, while leaving the important ones visible
      • Everything should happen in the most fluid way
  • KML Super Overlays
    • Solution
      • Create a pyramid like structure
      • Have Google Earth regions drive what is visible at each scale
      • Use a tile cache to maximize delivery speed
  • OpenGeo Suite Options
    • Community Edition – free
    • Enterprise Editions – four levels of support
      • Basic
      • Professional
      • Platform
      • Strategic

  • Helping the DOD/IC Easily create, visualize and publish data for situational awareness with the OpenGeo Suite
  •  
  • GeoServer
  • OpenGeo Suite – Key Features
    • Greater scalability & app control in combining enterprise data with Google's infrastructure
    • Additional geospatial capabilities to the Oracle platform
    • Seamless integration with ESRI, plus developer-friendly JavaScript components
    • Instant, wide access to data stores on Bing
  • A New Approach to Developing SDI
  • The CAPRA Program Central America Probabilistic Risk Assessment CAPRA is an ongoing initiative to develop and enhance a set of free and open source tools to understand , communicate and support decisions to reduce disaster risk within Central America.
  • Multiple Natural Hazards EARTHQUAKE HURRICANE INTENSE RAIN VOLCANO TSUNAMI GROUND SHAKING / LIQUEFACTION LANDSLIDES - GROUND SHAKING - HURRICANE RAINFALL - OTHER RAINFALL STRONG WINDS STORM SURGE HURRICANE RAINFALL FLOODS - HURRICANE RAINFALL - OTHER RAINFALL ASH FALLS BALLISTIC EJECTIONS PYROCLASTIC FLOWS LAVA FLOWS
  • Probabilistic Risk Modeling Risk (i.e. probable loss) Hazard (i.e. earthquake) Exposure (i.e. houses) Vulnerability (of house to quake) INFRASTRUCTURE ENVIRONMENTAL ECONOMIC SOCIAL - Disaster Impact Analysis - Scenario or Stochastic
  • SDIs and Collaborative Mapping Risk (i.e. probable loss) Hazard (i.e. earthquake) Exposure (i.e. houses) Vulnerability (of house to quake) 1) Locate the data that already exists 2) Access and share that data 3) Create the data that is not in existence
  • Meeting CAPRA Requirements
    • Need more participatory SDI building
    • Must improve/augment existing SDI platforms
    • Meet these requirements through developing and distributing open source, Web-based GeoNodes
  • The theory of SDI developed before we learned what was possible with the Internet…
  • Successful Internet projects have a vitality that encourages participation.
  • Align incentives to create a sustainable Spatial Data Infrastructure Necessary, but not sufficient to just have policies, requirements & mandates Necessary, but not sufficient to just have best-of-breed software Spatial Data Infrastructure (SDI)
  • – Tim O’Reilly “ Architectures of Participation” An “Architecture of Participation” is both social and technical , leveraging the skills and energy of users as much as possible to cooperate in building something bigger than any single person or organization could alone.
  • GeoNode = Web Portals + Web 2.0 User at the Center Compelling and relevant User Responsibility Reduce Barriers of Entry
  • GeoNode Principle Concepts Collaboration Distribution Cartography Data collection
    • Very simple to share data
    • Provide user statistics
    • Comments, ratings, tags
    • Collaborative Filtering
    • Rankings of best ‘views’ and data sets contributed
    • Highest rated, most viewed, most shared
    GeoNode is About Collaboration…
  • Usage Statistics Add Context…
  • Ratings Inform Search Results…
  • Comments improve collaboration...
    • Simple installation and distribution

    GeoNode Project Timeline
    • SDI-building institutions have high standards for metadata (ISO)
    • Social features of GeoNode depend on social metadata (ratings, # of views, comments, etc.)
    Challenge: Integrating Social Metadata
    • How to put social metadata into the metadata catalog?
      • Using & modifying GeoNetwork
      • Building a custom XML schema that extends ISO19139 with social metadata fields
    Challenge: Integrating Social Metadata
    • GeoNode requirements:
      • Open source
      • Focus on the user (rich profiles, content management, and social metadata, etc.)
    • Standard open source geospatial web tools lack this focus
      • Need a modern web application framework
    Challenge: Focus on Users
    • Most robust ones are in lighter-weight scripting languages
    • Geospatial applications require higher-performance languages
    Challenge: Which Web Framework?
    • Chose Django: mature & lighter-weight
      • Presents challenging build and deployment issues
      • But gained a strong community and great capabilities for building user features
    Challenge: Which Web Framework?
      • Work on the API's of GeoNode components
        • Improved styling widget library for GeoExt
        • Improved GeoServer REST API
        • gsconfig.py, a library for working with the GeoServer REST API
        • Patches to OWSLib
    Solution: Contributions to Open Source
    • Integrating existing tools & building new application code
    • Adding to the libraries and API's at the joints
    • Maximize potential for reuse
    Contributions to Open Source
    • GeoNode encourages Open Data
    • Some institutions love this
    • Others are concerned about data quality, misuse of data, etc.
    Challenge: Open Data
  • Solution: Give Users Control
  • Solution: Group Endorsement
    • Peru and Guatemala have started their own open source SDI initiatives
    • Quick progress, but no unified community
    Challenge: CAPRA & Other OS SDIs
    • Encourage common use of GeoNode as open source SDI throughout Latin America
    • Involve others in the developer community
    Solution: Build Developer Community
    • Haiti Data Dissemination Portal
    • Global Earthquake Model
    • ITHACA / WFP
    • Caribbean Community Climate Change Center
    • And more...
    User Community
  • Other Initiatives
    • OpenAerialMap
      • What's needed is a bright shiny core, well documented for others to work from.
      • OSM got that through the monk-like devotion, over a period of months/years, by the OSM founders
      • OAM is getting that from... nobody (post C. Schmidt)
      • OpenGeo pursuing partners and funders to revive OAM as a repository for contributions of raster data
