Hi all, The default memory limit for warp operations is 64MB, which is far too low using recent hardware and leads to inefficiencies in I/O when warping large images.
This can be changed using the -wm option of gdalwarp, or if using the API change the value of GDALWarpOptions::dfWarpMemoryLimit. More information here: http://trac.osgeo.org/gdal/wiki/UserDocs/GdalWarp#WillincreasingRAMincreasethespeedofgdalwarp However, it would be better to do both of the following: 1) Change the default value of 64 MB to something higher, perhaps depending on the machine's configuration (say 1/4 of RAM) - this possibility is mentioned in gdalwarpoperation.cpp . 2) Add a config option so that the default can be set for all operations by the user (which overrides 1, but can be overridden for each operation) Any comments? regards, Etienne _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
