QSWAT projection

[Diveshwar Shah]

Dear all,

I am working on QSWAT on Tappan Lake and trying to look for the 10m DEMs I found the dem and clipped it to the required watershed but when i use that in QSWAT it shows projection error and when i try to reproject i don't find the required projection for Ohio. the available one is in feet and when i go ahead with it another error pops us stating the cells are not square and one DEM that worked i could go abit further, it shows python error stating either it has virus or has unwanted software. And also where can we find the burn file. it will be really appreciated if someone helps me out. Hope to hear from you guys soon. Thank you.

Your Sincerely,

Diveshwar Shah

I am not sure what you mean by the required projection. Required by
who? I would avoid one that uses feet.

The burn file, if you want to use one, is for you to find.

You do not need to clip the DEM to the watershed unless you need to
because delineation gives you the wrong watershed shape. Clipping the
DEM to the boundary introduces errors in the slope at the boundary.
