Issue with HRU Creation – Request for Assistance

[Iman Soukrate]

Dear all,

I am writing to kindly request your assistance regarding a problem I encountered while attempting to create the HRUs.

I have prepared my land use map, which I downloaded from a French database, and the soil map, which I obtained from the FAO-UNESCO "Soil of the World" database. I have also prepared the corresponding land use and soil tables, which are attached to this message.

However, despite these preparations, I am unable to generate the HRUs. I receive the following error message:
"There is no crop or soil data for channel 94 (LINKNO 1) in subbasin 1 (and perhaps others)."

I am not sure where the issue is coming from, and I would greatly appreciate your help in identifying and resolving it.

Best regards,

[Chris George]

Typically this is caused by your landuse and soil maps not being
projected. A quick way to spot this is to click the Zoom Full button
and see your project split into two small pieces. Another symptom, if
they are really latlong files is a very small pixel size.

You need to reproject these files, not just assign a projection to them.
