[mapserver-users] KML as Outputformat returns incorrect coordinates

Wed Jul 6 08:55:39 PDT 2011

I had to adjust the height parameter to make it work when downloading as KML:

height = ((maxy-miny)/(maxx-minx))*width

It still seems like a bug, but does this help?  I guess the WIDTH and HEIGHT parameters don't make much sense when outputting as KML.

You might be hitting the same issue that I reported a few weeks ago 
(http://trac.osgeo.org/mapserver/ticket/3928).
