GIS info on the Internet

GIS is all about mapping stuff. I found some links to free GIS software. The US Census Tiger database is also available for download. Now all I have to do is think of things to map. Like our stations coverage in analog and digital transmission. Use your imagination.

Also, the coverage contour maps posted on the FCC website pointed me to an interesting method of generating maps using the tiger data:

If you notice in the instructions, you pass all the info about what you want on the map in the URL, including a link to a file that can contain many marked points. If you had a mathematical function that would generate a coverage contour (like your station's 60 dBu) of GPS coordinates, you could create your own contour maps with any of the other TIGER data that is available.

Example of marking a single point, inspect the URL

Lastly, if you haven't looked at Google Maps yet, wow are they cool.

I would really like to try some coverage map kind of stuff with Google Maps, but haven't had time to look at the Google Map hacks. I did try some of the other stuff with Firefox and Greasemonkey and I am very impressed by how programmable their service is.
