My height map is not being imported correctly

My 8 bit raw height map is importing as such:

I’m sure it has to do with the heightmap resolution setting:

but it doesn’t allow me to change it. The Resolution of the file is 10812x10812. Do I just need to down scale my resolution?

I think you have to scale down your resolution. And also for best results try to keep your dimensions = to powers of 2. For example 4096 * 4096 or 8192 * 8192.

Use RAW-16

I scaled it down to 4096 and now I am getting a blocky terrain. but I think that’s may be because the raw map is 8 bit. I’m currently trying to look for 16 bit resolution DEM maps. The one I am currently using is 1/3 arc-sec. I think I need to shoot for 1/9 arc-sec.

both yours and kishoreven’s answers are 1/2 correct. I had to downscale and convert to 16 bit for it to work correctly. now I just need to find 16 bit or higher version of the DEM map. I think going to 1/9 arc-sec resolution DEM map will do the trick.
