[Mapserver-users] Retrieving Cached Query, Attempt to modify in URL

[Fawcett, David]

I decided to modify the query directly to get the image that I wanted.  I set MAPEXT to 'shapes' and BUFFER to 20000 (map units are meters) so I get the facility that I am interested in and a reasonable amount of surrounding land to give context to the queried facility.
