I have several buffers to be added together (Cold, Hot, Raining, etc.), but they only need to be added if they exist.
So I currently have create buffer if Cold else no buffer. (I did convert polys to raster.) I want to set up a calculator that runs all of the buffers that exist. But I won't know which exist (large project with lots of weather specifications).
So far I am able to add them fine if everything is there, but if one specified buffer doesn't exist then it errors out.
