[Qgis-user] Opening Raster from ESRI .GDB
Hi All, I've Googled around, and it seems like this isn't currently possible, but wanted to check with folks on this list for any solution... A lot of data being produced by agencies is now available only as ESRI .gdb files. A dataset I'm particularly interested in working with is a gridded soil dataset ( http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/ref/?cid=nrcs142p2_053628 ) These particular data are in raster format, stored as Arc 10.1 .gdb, available from here: http://datagateway.nrcs.usda.gov/GDGOrder.aspx Any suggestions are appreciated. Thanks! Mike ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] Opening Raster from ESRI .GDB
Hi Even, Thanks a lot for the quick response - I really appreciate your work in dealing with the GDB files! That sounds great! Let me know if you need more data examples and such. Just a quick question - .gdb is not typically forward and backward compatible across Arc versions, right? [I've definitely had .gdb files that don't work in QGIS, while some do, so I have assumed that it was due to versioning issues - is that right? Or should I be doing some trouble-shooting?] Thanks again, and best regards, Mike On Thu, Jul 24, 2014 at 3:27 PM, Even Rouault even.roua...@mines-paris.org wrote: Le jeudi 24 juillet 2014 18:19:14, Michael Treglia a écrit : Hi All, I've Googled around, and it seems like this isn't currently possible, but wanted to check with folks on this list for any solution...

Re: [Qgis-user] Opening Raster from ESRI .GDB
Sorta, there are 2 drivers for GDB. The open GDB that Even has been working on and the official ESRI GDB api. The ESRI GDB api and Arc instance are not backwards compatible, once you upgrade a gdb to the latest it only works with the latest and there's often no way to write an older variant. The open GDB driver I think allows you to read any version and write older versions if you need to without auto-upgrading. Back to your original question does the ESRI gdb driver work for you use case for now? On windows I think you can get it with OSGeo4w on Linux you need to download the SDK from ESRI and recompile GDAL - but I don't know if this is vector and raster or just vector.

Re: [Qgis-user] Opening Raster from ESRI .GDB
Even, I believe that you meant that the ESRI FileGDB driver can only read files created by ArcGIS 10.0 or higher. Their driver does not work for 9.x files if I remember correctly. David.

Re: [Qgis-user] Opening Raster from ESRI .GDB
Even and Alex, Thanks! That definitely clarifies some things. I just tried two GDB files with ESRI FileGDB and OpenFileGDB in QGIS. One .gdb file worked fine with both ESRI FileGDB and OpenFileGDB. The other didn't work with either. I don't know what Arc version the latter was created in or anything, but I can try and find out and get back to you in the future.
