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.

Subject: [mapserver-users] Really general question about
Mapfiles and GetMaprequests
In a GetMap request what are the arguments 'height' and 'width'
measured in? Pixels?
Also what does changing RESOLUTION and SIZE in a mapfile
actually do?
MAP
...
RESOLUTION 300
SIZE 1667 1667
...
END
Thanks!
