This may work. An alternate method is if I do this through the Python GRASS interface, I can more easily create unique IDs that are not based on the simple "Cell #" algorithm I'm currently using. That is harder to do in bash.

Or just recompile GRASS to use LONGs for primary key rather than INT. 

For now I'm sticking with a lower resolution 90 m raster. Problem solved.

Thanks,
