What is the issue or question you have? An error shows while running the NDR model.

What do you expect to happen? find the place of occurrence of error.

What have you tried so far? Tried several times by changing type of csv table.

Pls help on recovering the error occurred.

Hi @tamasha,
This looks like an error with your CSV table. You can upload it here and I’ll try to identify the problem. Please also try updating to the latest version of InVEST, 3.14.0.

Dear E Soth

Pls see the attached csv file hereto and help me on this matter and I have tried several ways to overcome this matter. But failed.
Even change the bit depth of rasters. Failed.

Pls help on this matter.

Kind regards

Hello @tamasha , thanks for uploading your table!

The error is that you have a blank value in the proportion_subsurface_n column for the Rubber LULC code. All values for all columns must be defined for the model to work as expected.

Please try this out and let us know how it goes!
James

Dear James

Thanks a lot. The model runs properly. I didn’t see the blank value even I look at the table many times. I tried with value type in the CSV.
Thanks again for the support.

Kind regards

OK! Well, if the model is running as expected, then that’s great. Please be sure to let us know if you have any further questions by opening a new topic.

Thanks,
James

Dear James
The model runs correctly. Will be in touch when a problem arises while running the Invest models. Thanks for the great help.

Regards
Tamasha
