Hi,everyone,
I’ve met a problem about the Water Yield Model, about the value error as follows,

If someone can solve the problem, I will be very grateful for that, thanks.

Hi @yajiaoban,

Thanks for including your log file with the post. The KeyError: 0.0 means that either the LULC input raster or the associated biophysical table do not recognize 0.0. Does your LULC raster have 0.0 values and does your table have a row to handle them? Sometimes we see this when the LULC rasters nodata value is not set.

I also see you’re using a development version of InVEST 3.6.0. We would strongly recommend updating to the latest version of InVEST 3.10.2. Many bugfixes and updates have been made across the software.

Best,

Doug

Sorry, I have another question, that is, does the input of raster images with different resolutions have any effect on the final result of the model, and is it necessary to standardize the resolution before data input?

thanks，

Good question, the model standardizes and aligns all of the raster inputs for you, using the LULC raster input as the basis for the resolution, and a “nearest neighbor” resampling method. If you wish to have more control over the resampling methods used, you could certainly do this step yourself beforehand.
