>First off, thank you to everyone who has helped my

>>As with the demo, I am trying to use the NASA global mosaic in my geomoose
>application, but I may be having some problems with projections. I have
>defined EPSG:3071, which is the Wisconsin Transverse Mercator http://www.spatialreference.org/ref/epsg/3071/ >and all of my own data is in this projection, but the global mosaic does not
>recognize it. When I leave the wms in EPSG:4326 the image shows up, but
>it matches the map less and less at smaller scales. This can be seen on
>the demo here: http://gis.swwrpc.org/geomoose2/geomoose.html >(zoom in and it looks ok, but zoom out and it is way off).
>>I see that the default projection for the global mosaic is EPSG:4326, does this
>mean that I cannot reproject it in geomoose 2.0?
>>I followed the instructions here: http://www.geomoose.org/moose/howto/wms_project.html >but to no avail, which makes me believe it could be a problem with my
>configuration somehow. Should I instead write a mapfile to take the wms?
>>Here is the code from my mapbook (with the default projection):
>><map-source name="nasa" type="wms"
>> <param name="format"
>>...and here is my projection:
>>Proj4js.defs["EPSG:3071"] = "+title= NAD83(HARN) / Wisconsin
>Transverse Mercator +proj=tmerc +lat_0=0 +lon_0=-90 +k=0.9996 +x_0=520000
>+y_0=-4480000 +ellps=GRS80 +units=m +no_defs";
