I think this is the one.

I tried removing quotes and using CDATA but have not had any success yet. I think the quotes are not problem. I tried another projection from another map and it worked fine. The XML of the working file is below. <CoordinateSystem> PROJCS["WORLD-MERCATOR",GEOGCS["LL84",DATUM["WGS84",SPHEROID["WGS84",6378137 .000,298.25722293]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295 ]],PROJECTION["Mercator_1SP"],PARAMETER["false_easting",0.000],PARAMETER["fa lse_northing",0.000],PARAMETER["central_meridian",0.00000000000000],PARAMETE R["standard_parallel_1",0.00000000000000],PARAMETER["latitude_of_origin",0.0 0000000000000],UNIT["Meter",1.00000000000000]] </CoordinateSystem> <Extents> <MinX>0</MinX> <MaxX>0</MaxX> <MinY>0</MinY> <MaxY>0</MaxY> </Extents> <BackgroundColor>FFFFFFFF</BackgroundColor> <Metadata /> </MapDefinition> I think there must be something in the coordinate definition that does not work. <CoordinateSystem> PROJCS["unnamed",GEOGCS["unnamed ellipse",DATUM["unknown",SPHEROID["unnamed",6378137,0]],PRIMEM["Greenwich",0 ],UNIT["degree",0.0174532925199433]],PROJECTION["Mercator_2SP"],PARAMETER["s tandard_parallel_1",0],PARAMETER["central_meridian",0],PARAMETER["false_east ing",0],PARAMETER["false_northing",0],UNIT["Meter",1],EXTENSION["PROJ4","+pr oj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m [EMAIL PROTECTED] +wktext +no_defs"]] </CoordinateSystem> I need to educate myself on the parameters in these WKT coordinate definitions.
