I am very beginner and would like to customize ArcGIS using python scripting
for my thesis. I have to iterate Extract by Mask tool to extract several
raster layer using watershed boundary (vector) and tried to with the
attacthed code. But I am unable to get the result and got the following
error:
Running script multiExtract...
