Hi Mike, I have successfully performed lightweight load testing on the 64 bit Windows build with some ECW, MrSID, and TIFF data using the information contained at http://trac.osgeo.org/mapguide/wiki/MGOS22GdalProvider. So yes, for my data set I would say that it is stable.
There are a few limitations which may impact your implementation: Occasionally MapGuide does not correctly return the extents or coordinate system of the raster data. This makes authoring more difficult. Jackie has a patch to improve this behaviour attached to http://trac.osgeo.org/mapguide/ticket/740. The FDO GDAL Provider has only been tested with a single connection. [FeatureServiceProperties] DataConnectionPoolSizeCustom = OSGeo.Gdal:1 Enabling multiple connections may cause raster to go unstable. This means that MapGuide and FDO GDAL will only process one raster data set concurrently. If you have a lot of users and a lot different raster data sets, this could be a significant bottleneck. I would like to take another pass at MapGuide & FDO GDAL for the 2.4 release. There is some interest in adding configurable resampling (bilinear, cubic, etc) and we really do need to remove the single connection limitation. I can make time available to do this work if funding is available. This would move MapGuide + FDO GDAL Provider closer to parity with MapGuide + Autodesk Raster Provider.

Not complaining - just discouraged... Is GDAL working and stable in 2.2 - all kinds of different and older posts out there about partial work-arounds, Trevor’s investigation, locking it up, this is the problem, that’s the problem... We use imagery and it has been a struggle migrating through the releases and trying out the fixes - I do not want to move until I am sure how to handle the imagery. We have custom code all over the place and to migrate is a bit of an undertaking.... m -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Is-GDAL-working-and-Stable-in-2-2-tp6700721p6700721.html 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
