Hi! I am using GDAL 1.9.2 x64, Python 3.3 x64 and Windows 7 and I have a problem with infinite recursion in ogr.py. My initial call is: feature = ogr.Feature(layer.GetLayerDefn()) and the call stack: __init__ Python\lib\site-packages\osgeo\ogr.py __getattr__ Python\lib\site-pack

I have a Spatialite enabled SQLite file with both spatial and non-spatial tables. Since my database has a table called geometry_columns, all non-spatial tables are not loaded as layers. If I don't have a geometry_columns OGR attempts to load geometry from all the tables, but still loads n

Hi, You could start by merging all your tiff in a VRT then do gdal_translate -of Gtiff -co SPARSE_OK=TRUE -a_nodata 0 -co NBITS=1 -co "TILED=YES" -co "COMPRESS=CCITTFAX4" -co "INTERLEAVE=BAND" "example.vrt" "example.tif" Le 2012-11-13 17:14, Pietro Rossin a écrit : Hello all I have ~1000 ti
