  4. 4. What is Web 2.0? <ul><li>“ 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 ” </li></ul><ul><ul><li>--Tim O’Reilly </li></ul></ul>
  5. 5. What is a GIS? <ul><li>A digital representation of the earth, structured to support analysis (Dobson, 2007) </li></ul><ul><ul><ul><li>Automated systems for the collection , storage , retrieval , analysis , and display of spatial data (Clarke, 1995) </li></ul></ul></ul><ul><ul><li>Should also include dissemination </li></ul></ul><ul><li>Composed on software, hardware, and people </li></ul>

  12. 21. Geography 911 Project <ul><li>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. </li></ul><ul><li>Scope: ... provides to the community the means to share geotagged content and geographic data from multiple locations in multiple formats on the internet. </li></ul><ul><ul><li>Content and data can be uploaded into or embedded on individual layers then be displayed on a map of the Lawrence campus. </li></ul></ul><ul><ul><li>Examples of content may include photos, videos, text comments, vector-style locations (such as routes and “push-pins”), or user information </li></ul></ul>
