Hi (again), I have Oracle data with a CRSID of 81989 (British National Grid) and querying with King 0.7.3 in Studio 2008 - when I build maps I always use an arbitrary X-Y (metres) coordinate system because in the UK there is really little need to do coordinate conversion. I "expect" that unknown coordinates will be passed straight through (as per MapGuide 6.5) but MGOS seems to be more failsafe.
I have added the following lines to my C:\Program Files\Common Files\Autodesk Shared\Gis\CoordSys\11g\mapping.txt but to no avail: "British National Grid" = "GB_ORD1-MOD" "Ordnance Survey Great Brit" = "GB_ORD1-MOD" This is the server error: ERROR 6: Failed to initialize PROJ.4 with `+ellps=airy +units=m +no_defs '. projection not named If I try and preview the data in Studio with the layer I see the WKT of the coordinate system and the messaage says "The coordinate system is invalid PROJCS <[WKT defn]>" Could not create coordinate system forward transformation with specified coordinate systems. Exception occurred in method MgCoordinateSystem.MgCoordinateSystem at line 77 in file c:\build_bond_area\mapguide_open_source_v1.2\build_18.1\mgdev\common\geometry\CoordinateSystem/CoordinateSystem.cpp Is Studio erroring based on the Mentor 11g libs it installs and Server erroring on PROJ libs? Is there a way to add a CS to PROJ? It would be nice to define a coordinate system override in the Layer definition also... Any help greatly appreciated, Crispin -- View this message in context: http://www.nabble.com/Coordinate-Conversion-from-Oracle-%28King%29-Failing-tf4534737s16610.html#a12941238 Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
