Robert, For GetMap, height and width are measured in pixels. I would like to just point you to http://www.opengeospatial.org/standards/wms , but nothing is particularly easy to glean from the OGC... Plus, I will have to put in a request to my Attorney General staff before I can click through the giant legal agreement required to view the WMS spec. Seriously, what the #$%&! For the map file info, look here: http://mapserver.org/mapfile/map.html >From that page: SIZE [x][y] Size in pixels of the output image (i.e. the map). RESOLUTION [int] Sets the pixels per inch for output, only affects scale computations and nothing else, default is 72. I don't believe that SIZE comes into play when you are requesting a layer as WMS because you are required to specify height and width in your getMap request.

Pixels? Also what does changing RESOLUTION and SIZE in a mapfile actually do? MAP ... RESOLUTION 300 SIZE 1667 1667 ... END Thanks!
