Error CSR

[楊毓婷]

  Hello, I would like to ask why this error occurs. I have checked all my files, and both the watershed, land use, soil, and even QGIS itself are set to EPSG:3826 – TWD97 / TM2 zone 121. However, after the second step (Create HRUs), the generated slope DEM always ends up with a different CRS. Could anyone please advise me on how to resolve this issue? Thank you very much.

Please if you can help with my work on Modeling the Impact of LULCC on Water Balance in Ghana: A case study of the Densu River Basin.

I presume you mean the slope bands file by the 'slope DEM'. suspect
this does not matter because the CRS's involved are really the same.
But if you send me a zip of your project folder I will investigate.
