I'm trying to do a math operation in raster calculator using the rasters from other two raster calculators.
My calculation is a simple NDVI formula:
(rastcalc4 - rastcalc3)/(rastcalc4 + rastcalc3)
It works well in most of the cases, but, sometimes it fails and this error shows up:
ERROR 000539: Error running expression: rcexec()
Traceback (most recent call last):
File "", line 1, in
File "", line 8, in rcexec
RuntimeError: ERROR 999998: Unexpected Error.
Failed to execute (Raster Calculator (3)).
I don't understand what that means, how can i fix it?
