What I want to do is take the 2010-2019 and 2040-2049 rasters here and create a new layer that highlights only pixels where the value rises above freezing (0°C) between them. The end result will show where we can expect permafrost to thaw in the next 20-ish years in Alaska.
I've worked with rasters only a handful of times, so I feel a bit out of my element here. Are there any tools, equations, etc. for accomplishing this?
Hello Dan! Thank you for the suggestion. I attempted to perform the calculation, but I received the following error:
ERROR 000539: Error running expression: rcexec()
Traceback (most recent call last):
File "<expression>", line 1, in <module>
File "<string>", line 8, in rcexec
RuntimeError: ERROR 010240: Could not save raster dataset to 2010_2040 with output format GRID.
Failed to execute (RasterCalculator).
I'm not sure why it would be throwing this error. Any ideas?
save it as a tiff in a folder, which is the preferred raster format
GRID's cant begin with numbers and there a whole load of other restrictions
