[Geomoose-users] Data Projected in wrong area

[Brent Fraser]

Joshua,

     From your posts, I assume you want to display the data in EPSG:3857 
to allow overlaying your data on to Google/Bing/Yahoo map layers?  And 
your data is currently stored in 
NAD_1983_StatePlane_Missouri_West_FIPS_2403_ **Feet** which (according 
to SpatialReference) is not defined by EPSG, but is defined by ESRI.  
EPSG does define the State Plane zone with units of meters, EPSG:26998, 
but that won't help.

So the only part of the configuration that needs to define the State 
plane zone is in the LAYER's PROJECTION object (it specifies the 
coordinate system of the source data).  The MAP's PROJECTION object 
needs to define the target coordinate system (EPSG:3857) as mapserver 
will handle the re-projection from the source system to the target 
system.  And the GeoMoose needs only to be configured for EPSG:3857 
since there is no need for it to know about the coordinate system of the 
source data.

In your Mapserver map file, the LAYER should have

LAYER
     PROJECTION
         'init=esri:102698'
     END

(note the esri, not epsg as the defining authority).  And the MAP object 
should have

MAP
     PROJECTION
         'init=epsg:3857'
     END

Best Regards,
Brent Fraser
