    • First section will focus on
          • History of PPGIS,
          • Role of PPGIS in Environmental management/monitoring and planning
          • Social Systems a new paradigm for PPGIS
            • Assignment #1
            • Mid Term
    • Second section will look at
          • The tools and technology of the Geospatial web
          • Design of Geospatial systems for the web
          • GIS Standards

    • Course outline
    • Presentations
    • Assignments
    • Etc.
  • Exercise: Affinity Model
    • Fun with an Affinity Model
    • What is it?
      • It’s a process of seeking clarity about complex ideas or problems.
  • What will we explore
    • What are the elements that make something a GIS?
    • What makes a project or initiative participatory?
  • Affinity Model Plan
    • Step 1 - Generate ideas
    • Step 2 - Display ideas
    • Break 10 minutes
    • Step 3 - Sort ideas into groups & Create grouping titles
    • Step 4 - Draw finished diagram
  • Creating Grouping Titles
    • An idea that captures the essential link among the ideas contained in a group of cards.
      • Phrase or sentence
      • Clear meaning
  • Topic 2
    • History of GIS
      • Open and Closed GIS
      • History of Web GIS
      • Accessibility of GIS
      • Examples
      • Discussion
  • What is GIS?
    • Geographic Information Systems (GIS) are computerized systems for the storage, retrieval, manipulation, analysis, and display of geographically referenced data.
  • History of GIS
  • Accessibility
    • Accessibility is a complex issues in GIS that has many facets
    • Data
    • Software
    • Knowledge
    • Usability
  • Accessibility
    • Over time GIS has become more accessible for several reasons:
      • Faster and more affordable computers
      • Data sharing and Data standardization
      • Open Source Movement
        • Access to the code meaning more customizability
  • Accessibility Desktop GIS
  • Accessibility Web GIS
    • Web GIS itself has evolved in a similar fashion
    • Starting first with expensive highly complex proprietary software
    • Moving to ‘Out of the box’ applications
    • To free Open source applications that are highly customizable
  • Accessibility Web GIS
  • Types of Web Maps
    • Static web maps
      • Static web maps are view only with no animation or interactivity.
    • Dynamically created web maps
      • These maps are created on demand each time the user reloads the web pages, often from dynamic data sources, such as databases.
    • Distributed web maps
      • Maps are created from distributed data sources. The interface of the web mapping system provides a method to access maps on other servers.
    Types of Web Maps
    • Realtime web maps
      • Realtime maps show the situation of a phenomena as it is occurring.
    • Personalized web maps
      • Personalized web maps allow the map user to apply his own data filtering, selective content and the application of personal styling and map symbolization.
    • Open, reusable web maps
      • Web maps in this category are usually more complex web mapping systems that offer APIs for reuse in other people's web pages and products. An example for such a system with an API for reuse is Google Maps.
    • Collaborative web maps
      • These maps allow simultaneous editing of spatial data across the web.
    Types of Web Maps
  • Summary
    • GIS has evolved from task specific tools to more generalized applications
    • It has also become more accessible to more people because it has become more:
      • Affordable
      • Easier to use
      • and accessible
    • Web GIS has evolved and diversified in a similar fashion closed GIS.
