[mapserver-users] distance search in PLSS

[Puneet Kishor]

http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PerlMapScriptExamples35ex12

I have posted a perl script called plsscalc.pl at the above wiki. Given 
a township, range, section, quarter-section, and a search radius in 
miles, this script will spit out all the quarter-sections within the 
search radius of the origin. Assumes regular and continuous coverage of 
PLSS.

Hope this helps someone.
