Slashdot's audience is knowledgable. We've been doing some work with campus visitor maps here at the University of California, San Diego. Curious what you think? Public maps are located at:
http://maps.ucsd.edu/
Some features include dynamic image processing, historical aerials, spatial location indices and graphical responses to location lookups. Viewport scales from a large monitor down to PDA. The client-side is any generic web browser. Server is a PIII-733. Behind the scenes we're doing DBMS driven polygon fills and real-time layering (eg. GIS/CAD) in a browser.
If you get the inclination, feel free to browse around. Any feedback, suggestions or ideas for improvement are welcome.
Abe Lempel, Jacob Ziv and Terry Welch Discovered a neat algorithm to squelch CompuServe incorporated it into the GIF Good programmers soon caught the drift The format was published, free and open Many useful things started to happen Then Unisys Corp purchased the rights And changed the terms on LZW overnight The useful algorithm was off limits Ransom to corporate greed and profits On June 20, 2003, the LZW patent expired Shame on Unisys for what has transpired Someday Unisys books will be in arrears While the ideas of LZW survive the years

Discovered a neat algorithm to squelch
CompuServe incorporated it into the GIF
Good programmers soon caught the drift
The format was published, free and open
Many useful things started to happen
Then Unisys Corp purchased the rights
And changed the terms on LZW overnight
The useful algorithm was off limits
Ransom to corporate greed and profits
On June 20, 2003, the LZW patent expired
Shame on Unisys for what has transpired
Someday Unisys books will be in arrears
While the ideas of LZW survive the years
