There is no detailed info, the only document is the user guide: http://trac.osgeo.org/mapguide/wiki/maestro/UserGuide
Are you using the Maestro 2.0 RC1 ? If not, try it. If yes, can you post the entire message (if there is more) ? Regards, Kenneth Skovhede, GEOGRAF A/S On 02-02-2010 12:35, hanane el yazidi wrote:
I'm a MGOS novice. I'd like to add a raster (.tiff) with Maestro, so I added an alias pointing to the directory where the raster is located, then I added a dataconnection with the FDO Gdal provider, tested the connection, and it was good. But when I want to add the raster layer, I get this error: "/Failed to read schema from data source. The operation gave the error message: Value cannot be null. Parameter name: input"/. What am I doing wrong? is there some detailed documentation about the use of raster data in maestro.
