[SWAT-user:2223] how to use SRTM data in Arcswat

[Smita Bodhankar]

Hi all

I am a new user of Arcswat. I want to delineate watershed from DEM. I have downloaded SRTM data, but the arcswat wants the data in grid format. I have tried converting the data in Arc GIs... using save as grid.. but it is not working.

Could anyone help?

Using Gdal you should be able to convert the data:

I think SWAT directly use SRTM DEM, i did my work using SRTM data
directly without any editing.

U may chang the selection of DIM formate option while u work in SWAT
directly.
