interesting application...

[Stephen Lime]

Here's an example application that uses a simple perl script to function, but all
data where built using MapScript. Check out:

Basically it's a USGS DRG viewer for the State of Minnesota and functions like
the TerraServer and TopoZone. MapScript was used to bust the 3 USGS map series
DLG data into 360,000 GIF images. A simple perl script is used to assemble pieces
into maps of arbitrarily large size. This technique is well suited to the quad maps since
infinite zoom doesn't work well with line art. Another nice benefit is that individual GIF
images are cached so there is less overhead for both the server and the client.
