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