SDR intermediate outputs: file weighted_avg_aspect.tif

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 manual) and it seems to me that the weighted_avg_aspect.tif file can help me with this.

Hi @BiancaBendito, thanks for bringing this to our attention.

It looks like weighted_avg_aspect.tif was removed in InVEST 3.14.0 when there was a major update to the SDR LS factor. (If you’re curious, you can read more about that update in the 3.14.0 changelog and in the decision record ADR-0001: Update the InVEST SDR LS Factor). I’ll make sure we get the User Guide updated!

You should be able to find what you’re looking for in intermediate_outputs/ls.tif.

I’d just also like to add that although it was removed in InVEST 3.14.0, this was in error and we will soon be restoring this output of the SDR model for consistency with Desmet & Govers (1996).
