Hi Jason, thank you for your input. I have tried to set an override Coordinate System but it seams like Maestro is ignoring the override. By default the source coordinate system is (BYN75) which is the name of my tab file, I find that a littel strange.
In the override I set the target to (ESPG 25832) and then I validate my map, now I get an error that Maestro could not get the spatial information from the datasource. If I then change the source coordinate system of the override to the Wkt PROJCS["unnamed",GEOGCS["unnamed",DATUM["Euref_98",SPHEROID["GRS 80",6378137,298.257222101],TOWGS84[0,0,0,-0,-0,-0,0]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]],PROJE CTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",9],PARAMETER["scale_fact or",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["Meter",1.0]] Like this Then I get the conversion warning I had from the start hmmmm I have noticed another thing when I switch between Simple and extended view It loads the default coordinatsystem Jason Birch <[email protected]> Sendt af: [email protected] 18-11-2010 17:11 Besvar venligst til MapGuide Users Mail List <[email protected]> Til MapGuide Users Mail List <[email protected]> cc Emne Re: Vedr.: [mapguide-users] Re: Coordinate system problem validating a map Well Known is a bit of a misnomer for this stuff. Most tools (MapInfo, ESRI, etc) have their own subtly different flavours. You should be able to set an override Coordinate System on your data source to avoid this, but I haven't tried it myself to see if Maestro reads the override.

When i check the coordinate systems in Maestro the WKT code says for the Datasource (MapInfo .tab file) : PROJCS["unnamed",GEOGCS["unnamed",DATUM["Euref_98",SPHEROID["GRS 80",6378137,298.257222101],TOWGS84[0,0,0,-0,-0,-0,0]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]],PROJE CTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",9],PARAMETER["scale_fact or",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["Meter",1.0]] and for the Map coordinatsystem it is PROJCS["ETRS89.UTM-32N",GEOGCS["LL-ETRF89",DATUM["ETRF89",SPHEROID["GRS1980",6378137.000,298.25722210],TOWGS84[0.0000,0.0000,0.0000,0.000000,0.000000,0.000000,0.00000000]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["false_easting",500000.000],PARAMETER["false_northing",0.000],PARAMETER["central_meridian",9.00000000000000],PARAMETER["scale_factor",0.9996],PARAMETER["latitude_of_origin",0.000],UNIT["Meter",1.00000000000000]] I just don't understand that when I set the Coordinatsystem (ESPG code 25832) in MapInfo it gives something different i Maestro ? _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
