010066: RegionGroup: Unable to allocate required memory of <value> bytes.

Description

The amount of memory required to run the Region Group tool is not available. This tool can consume a lot of system resources, particularly if your input raster has a lot of small-scale variability.

Solution

Some suggestions to avoid this problem are as follows:

  • Close down any unneeded applications to free up system resources.

  • Increase the virtual memory allocation for your system.

  • Reduce the size of your dataset to process it in sections.

  • Simplify your data by filtering it. This can be done with tools such as Majority Filter, Aggregate, Shrink, and Focal Statistics.
