[mapguide-users] RE: Measuring distances mismatch

[Mike Adair]

And are you specifying the projection details in the 
ApplicationDefinition.xml file? 

I thought we had a wiki page for it but I can't find it at the moment 
but for projections other than EPSG:4326, you need to specify the 
projection details in a <ProjectionDef> element inside the 
<Map><Extension> element. like this (the example is an LCC projection):

<ProjectionDef>+title=LCC +proj=lcc +lat_1=49 +lat_2=77 +lat_0=49 
+lon_0=-95 +x_0=0 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m 
+no_defs</ProjectionDef>

The string that goes in there is the PROJ.4 initialization string that 
Proj4js can parse.  Proj4js can't parse the WKT that MapGuide uses at 
the moment.  The assumption of an EPSG:4326 projection is in OpenLayers, 
so unless you tell it otherwise, you will get EPGS:4326.
