1. CS 128/ES 228 - Lecture 14b1 Maps on the Internet

2. CS 128/ES 228 - Lecture 14b2 Why Put Maps on the Internet? Mapquest, MapPoint, Googlemaps, YahooMaps, etc. BUT ALSO… So much of GIS output is in the form of maps that it would be useful to allow that output to be “served” through the net.

3. CS 128/ES 228 - Lecture 14b3 ArcIMS  Internet map server connected to Arc software  Capabilities  Deliver dynamic maps (and DATA) through the web  Restrict user interface to something more appropriate than ArcView  Bring modern web technology into GIS world

4. CS 128/ES 228 - Lecture 14b4 Example 1 – Reuters AlertNet Series of GIS layers (world-wide) connected to an index (menu) featuring areas of interest to humanitarian/relief workers/agencies www.alertnet.org

5. CS 128/ES 228 - Lecture 14b5 Example 2 – The Lewis and Clark Project Museum set piece Provides limited access to an otherwise rich database Currently off line? lewisandclarkeducationcenter.com

6. CS 128/ES 228 - Lecture 14b6 Example 3 – Greenwood County Classic ARC-like interface Visual BASIC.Net back end (also uses ActiveX) “Lightweight” GIS – designed to load and compute quickly 165.166.39.5/giswebsite/default.htm

7. CS 128/ES 228 - Lecture 14b7 Example 4 – San Francisco Prospector Business information database Extensive queries Aerial photos Access to other databases www.sfprospector.com

8. CS 128/ES 228 - Lecture 14b8 Concerns for GIS/Maps on the Internet How much to restrict user interface? Who is the audience? What are the copyright issues? What are the privacy issues? What technology to use? Support all browsers or just some? Programming language or just scripting?

9. CS 128/ES 228 - Lecture 14b9 More Concerns... Hosting/serving issues Who hosts? Data Security? Are on-line updates permitted or only queries? Capacity? Scalability? Develop on-line or “port” upon completion?
