[mapserver-dev] FW: [MapServer] #3519: map UNITS AUTO from PROJECTION units

[Lime, Steve D (DNR)]

Seems like a reasonable idea but also one that I would think has been discussed 
before. Thoughts?

 I think that map UNITS should be initialized automatically depending on
 the PROJECTION used.

 Is there any sense in using a projection in meters (UTM) and setting map
 UNITS in degrees?

 Since a wms client can ask for a map in different projections, i think map
 UNITS should be automatically detected. Otherwise any layer with SIZEUNITS
 other than pixels is drawn wrongly when map units are different from
 projection units.
