I am trying to setup a custom basemap using a GTiff in the IAU's Moon2000 projection (30100 or 30101). The basemap image was originally created through gdal_merge and gdalinfo returns the expected, human-readable WKT CRS information.
As per the geoserver documentation, I then used gdal_retile.py to automatically generate my pyramids and the accompanying directory structure. This was then moved into /data-dir/data. A new workspace, for organization, and new store were created. I am able to add the basemap "layer", using the pyramid plugin, but the CRS defaulted a UTM zone (18N).
As per the geoserver documentation, I then edited the epgs.properties file and added the single line WKT from the link above. Through the geoserver web administration tool, I can see that the CRS was successfully added, but the wkt is empty. See the screenshot below.
I suspect that I now need to go in an manually add both a custom datum and spheroid. Is this the case? If so does anyone have documentation of this process? Has anyone gotten planetary data (any planetary body) added to geoserver as a basemap?
The end goal is to server the tiled basemap as a WMS to openlayers.
