Hello everyone. Good afternoon. What is the problem or question you have? The intermediate_outputs folder of the SDR model does not contain the weighted_avg_aspect.tif file. What do you expect to happen? I need to know or infer what the value of the L-Factor of USLE is (equations 69 and 70 of the …
