I need to extract values from about 30 raster datasets (each about 500 MB in size, signed 32 bit) for about 1500 points.
When I use the Extract Multivalues to Points tool, it quickly consumes all my memory (16 GB) and it never finishes. I must admit I only left it running for about an hour, but that is more than the whole process took in ArcMap.
It seems the tool is extremely memory intensive and I wonder if somebody has any suggestions how to get around it.
An obvious option is to use the Extract Values to Points tool repeatedly. Any other ideas?
