[seul-edu] New educational app--geography

[Doug Loss <dloss@suscom.net>]

I just saw this on Freshmeat:

http://www.tkgeomap.org/

Tkgeomap is a set of extensions to Tcl/Tk for displaying and
interacting with geographic data...Tkgeomap is not a full featured
geographical information system. For example, calculations assume
the Earth is a sphere, and data is stored in internal data
structures at single precision, giving a resolution of about 10
meters. This is good enough for my work (meteorology). If you need
more accuracy, you should probably use a GIS, such as GRASS. All of
the data in Tkgeomap is vectorized, which is to say information is
stored in arrays and tables of latitudes and longitudes. It does not
display or manipulate rasterized images.

Hopefully, Tkgeomap will provide others with useful geographic data
access and insight with minimal spin up time.
