[OpenMap Users] OpenMaps LLXY Projection with UMN MapServer

All,

Has anyone had the experience of having raster map data, returned from a WMS
in WGS 84 or EPSG 4326 lat long projection, being displayed incorrectly in
OpenMap?

In my openmap.properties file, I specified the following projection:

openmap.Projecion=com.bbn.openmap.proj.LLXY

Raster data from two different WMS services appear to be misaligned with
vector data on the map when zoomed out (1:70 000 000). At this scale, from
the lat/lon overlay lines, the projection of the OpenMap appears to be
Mercator. The mouse cursor readout agrees with the lat/lon overlay lines,
also.

When using higher resolution raster data from one of the above mentioned map
services, there is no noticable misalignment.

Any help would be appreciated.

Thanks,

Jeff
