Jeremy,

I wonder if you are not going at this in too complex a way.  At the
City here, we just set the coordinates to Ramsey County for all the
source layers in the interface.

Any layers that we need to import (like the LMIC aerial photos) into
the GeoMoose application, we use Mapserver for handling the reprojection
aspects.  

This greatly simplifies the Client managability and also allows for the
most flexibility with regard to importing other layers.

Without implementing some sort of Client side Reprojection routines,
this is the only method available to pull together separate projection
systems into a single map at the client end.

Currently Geomoose  doesn't support this type of functionality.  The
only reprojection capabilities in GeoMoose at this time are the Mouse
tracking coordinate readouts, to add in the capability of seeing LAT/LON
while dragging the mouse in the map view.

Does this clear it up or add in more complication to the responses
you've gotten?

Brian,

Following, I included the whole Map File:

MAP

      SIZE 800 650
      STATUS ON
      EXTENT 478856 4996794 488857 5006525

      SYMBOLSET '../symbols/symbol.sym'
      TRANSPARENT TRUE
      PROJECTION 
            "init=epsg:26915"
      END

      QUERYMAP

            STYLE SELECTED
      END

      WEB

"/ms4w/apps/GeoMOOSE/maps_statedemo/web_config.map"
      END

      LEGEND
            STATUS ON
      END

      LAYER
            NAME 'parcels'
            TYPE polygon
            STATUS ON
            DATA './blaine.shp'
                  PROJECTION
                        "init=epsg:99999"
                  END
            CLASS
                  NAME 'Blaine Parcels'
                  OUTLINECOLOR 0 0 0
                  TEMPLATE void
            END
      END

END ## end Map

I did as you suggested and added the PROJECTION line in the definition
of the Map File.  Unfortunately, it still does not work.  You will see,
also, in the Layer definition, I have the PROJECTION set to 99999.  I
added this code to the EPSG file to define the Anoka County coordinate
system.  

# NAD 1983 StatePlane Minnesota Central FIPS 2202 Feet
<99999> +proj=lcc +lat_1=45.06666666666667 +lat_2=45.36666666666667
+lat_0=45.0352777778 +lon_0=-93.26666666666667 +x_0=152400.3048006096
+y_0=30480.06096012192 +ellps=GRS80 +datum=NAD83
+to_meter=0.3048006096012192 no_defs <>

As I stated in a previous post, this works just fine in pMapper and I
wonder if it is not due to the fact that in pMapper there is only one
Map File that contains every layer.  

How would GeoMOOSE handle this issue if there was a WMS layer being
added that was of a different projection?

Thanks again for any help on this.

Jeremy,

I think the problem is you do not have a projection object defined in
your mapfile so MapServer does not know what to project it to.  Take a
look at these instructions:
http://mapserver.gis.umn.edu/docs/reference/mapfile/projection

So you would need to add this to your mapfile, so MapServer knows to
project that layer to UTM 15.
PROJECTION 
"init=epsg:26915"

Here is the map file for our city parcels.  All of the other map files
are exactly the same.  I also included the statedemo.xml and
stateconfiguration.js files.

Jeremy,

Can you send your mapfiles to the list, so I can take a quick look?

I am trying to develop a GeoMOOSE page for the City of Blaine and am
still in the "tinkering" phase.  I am running into, it sounds like,
the
same issue as posted in this thread.  I am trying to create a mapfile
for our parcels, something very simple, but leaving them in Anoka
County
coordinates.  So far, I have not had much luck.  

The first MapServer site that I developed was with pMapper and was
able
to display layers from different coordinate systems.  I just ended up
adding a couple lines to the EPSG file that described the Anoka County
coordinates and it seems to work fine.  When creating the mapfiles in
GeoMOOSE, I have tried adding the same lines to the MAP area and the
LAYER area of the mapfile with no success.  Any ideas/suggestions?
