Drawing the horizontal projection of the subsurface features from a radar visual in the Snap program, I mean, how do I convert it from this format to the gpr format, and which programs do I need?

[@ziadabdeldayem6884]

Sorry. I have not done this before.

[@naderdmaidi2129]

Is this DEM workable in HEC-HMS ? Or need for any process before exporting to HEC-HMS? “Note: I download from same site but unfortunately couldn’t define terrain date in HEC-HMS by using this DEM, so any advice ?

[@ziadabdeldayem6884]

I have not delt with HECHMS before. You may need to check (and change) the DEM format that works with HEC and also pay attention to the coordinate system.

[@ziadabdeldayem6884]

@@fekadugemeda2707You need to extract the zipped folder. If you have done that and still have the issue, try to download your data again.

[@ziadabdeldayem6884]

It depends on the country you're in. I think Lidar data would be good for your needs.

Does this model need to fill?

[@ziadabdeldayem6884]

Hi Aya. I have not checked that. But if it requires filling, you can interpolate to estimate the missing values.
