Finding usable DEMS in this day and age

[tspco]

I know this has been discussed before, I have been using Cadmapper to get my DEMS, it works OK but getting exactly what you want is difficult, without a satellite view to go by.
I just spent the past hour or so trying to find what I want on the USGS site nothing that will work with SU2017 make.
Ideas for other sources?

What is it you actually need and in what area? How will the data get used?

I've used this in the past because you can download RAW file that's 32bit. Even the default PNG can give good results depending on how distant you are....

Out place in the Nebraska panhandle, I am doing some virtual scenes of what I want to do.

I downloaded a png, there must be more to this?

The PNG has black to white values. Pure black is no height and pure white is highest point.

Displace a subdivided mesh using this PNG as the driver for the height. Your subdivided mesh should match the pixel density to the PNG to get accurate results.
