I don't think you are doing something wrong. This is just a limitation of the implementation of GetFeatureCount() in the shapefile driver. When there are no attribute or spatial filter set, it returns the total number of records in the DBF file. When you delete a feature, it marks the corresponding record as invalid, but doesn't actually remove it from the file, so the total number of records remains unchanged. You can "repack" the .shp, .shx and .dbf files by running shp.ExecuteSQL("REPACK locais") (see http://gdal.org/ogr/drv_shapefile.html) _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
