Hello NatCap team,
I’m starting to use the UC model (InVEST V3.11.0). I was able to test the model and it’s working fine. My LULC layer is 10m*10m and the building footprints are well defined (which helps to assess building intensity).
However I’ve a question related to the “cooling capacity calculation method” parameter.
The model allows to decide to use “weigheted factors” (my run 1) or “building intensity” (my run 2).
I’ve tried both and the results are quit different visually (on QGIS) and quantitatively:
For run 1 my “avg_cc” average is 0.48.
For run 2 my “avg_cc” average is 0.93.
So here is my question : Is there a way to decide which calculation method to choose? In other words, which one is the most accurate calculation method?
You can see below illustrations of the results (run 1 and 2 have the same symbology to be able to compare the results).

Heat (red) to cool (blue) island layer created by Québec ministry team. This layer helped me to check that my biophysical table were well done:
Run 1 (weighted factor):
Run 2 (building intensity):
Thanks in advance for your answer and thanks for the great models you create!
