2. The threshold point of the learning curve is typically around the two year time frame. - J. K. Berry (Berry & Assoc) GIS Learning Curve ~ 2 years

3. Google Earth's intuitive interface allows everyone in the organization to interact meaningfully with technical datasets without any expensive, time-consuming formal training. - USGS Google Earth Learning Curve ~ 2 hours

4. KML [Keyhole Markup Language] Source

5. Geographic Information Sharing w/ Google Earth KML KML from student 1 KML from student 2 KML from student 3 upload KML files to server or parse KML into database

6. Why Parse the KML into Relational Database? User submitted filenames might conflict, database can assign each submission a unique ID Once in the database the features, filenames, user names, & course names can be queried or sorted Query results can be recompiled into KML on-the-fly Entire Submission / Query process can be web-based and accessible by all participants

7. User-Created KML to Database / KML Download

8. Uploading KML Save original KML file Parse KML contents into Relational Database Acknowledge KML submission showing points on map Convert each KML file into GML

9. Downloading KML Download each KML file as it was submitted Download all KML submitted by each user Download all KML submitted for each course Download KML files based on query results

10. Geographic Information Sharing Tool All KML from student 1 All KML from student 2 All KML from student 3 KML A from student 1 KML B from student 1 KML A from student 2 KML A from student 3 KML based on query
