With QGIS 2.14.21 (code revision ea983fa869), GDAL/OGR 2.2.3, gdal-filegdb 2.2.3-2, on Windows 7 SP1 64 bit,
and sample File Geodatabase https://trac.osgeo.org/gdal/attachment/wiki/FileGDB/test_fgdb.gdb.zip attached to https://trac.osgeo.org/gdal/wiki/FileGDB

QGIS fails to add the geometry layers in the above sample FileGDB, either selecting "ESRI FileGDB" or "OpenFileGDB" as source type, with the following errors:

Invalid Data Source: C:\TMP\test_fgdb.gdb|layername=test_lines:2 is not a valid or recognized data source
Invalid Data Source: C:\TMP\test_fgdb.gdb|layername=more_test_lines:2 is not a valid or recognized data source
Invalid Data Source: C:\TMP\test_fgdb.gdb|layername=test_points:2 is not a valid or recognized data source
Invalid Data Source: C:\TMP\test_fgdb.gdb|layername=test_areas:2 is not a valid or recognized data source

The "Select vector layers to add..." window reports "Unknown WKB" in the "Number of features" column and the numbers 3001, 3005, 3006 respectively for point, line and polygon geometry type layers.

ogrinfo correctly handle the above sample FileGDB and reports (either with driver "FileGDB" or "OpenFileGDB" enabled):

C:\TMP>ogrinfo test_fgdb.gdb
INFO: Open of `test_fgdb.gdb'
1: basetable_2 (None)
2: basetable (None)
3: base_table1 (None)
4: test_lines (3D Measured Multi Line String)
5: more_test_lines (3D Measured Multi Line String)
6: test_points (3D Measured Point)
7: test_areas (3D Measured Multi Polygon)

As reported, for example, at https://www.ibm.com/support/knowledgecenter/en/SSGU8G_12.1.0/com.ibm.spatial.doc/ids_spat_285.htm the above mentioned geometry type numbers match as follow in wkbGeometryType const:

wkbPointZM                = 3001
wkbMultiLineStringZM      = 3005
wkbMultiPolygonZM         = 3006

but it seems they are not recognized by QGIS.

#1 Updated by Andrea Giudiceandrea over 6 years ago

I can open without errors the sample FileGDB with the previous versions:
- QGIS 1.8.0, GDAL/OGR 1.9.2, gdal-filegdb-1.8.0-1
- QGIS 1.9.0, GDAL/OGR 1.9.2, gdal-filegdb-1.9.2-2

and the geometry types are recognized as Point25D, MultiLineString25D and MultiPolygon25D respectively.

So I think it seem a regression.

#2 Updated by Giovanni Manghi over 6 years ago

  • Status changed from Open to Feedback

Tested on 2.18.15 on Linux and Win10, with both the open and the closed driver: no problem whatsoever.

#3 Updated by Andrea Giudiceandrea over 6 years ago

The bug is also present in current version 2.14.22.

#4 Updated by Giovanni Manghi about 6 years ago

  • Resolution set to not reproducable
  • Status changed from Feedback to Closed

Please try with a more recent version as now (that QGIS 3 is out) QGIS 2.14 is officially obsolete. With more recent versions (2.18 and 3) the issue is not replicable.

Reopen if necessary.
