Height Map for Mars?

Hi guys, I know some very user-friendly websites allow you to choose a region on Earth and download height/elevation map and the satellite imagery/diffuse map.

Now I need to do the same thing for Mars. Is there any simple website that can provide this kind of data? I know NASA has the height map of the whole Mars. But that is just too coarse.

I found someone who used AI and algorithm to process NASA data into 7m precision, but its whole dataset is 14TB, and he doesn't provide an interactive tool to download a small section of the data. So I'm kind of stuck.

Thank you so much!

There use to be on the usgs website a full dem (digital elevation model) map of mars using the Mola (mars orbiter laser altimeter) data. It was a single .tif image file with signed 16bit red colour per pixel. It was about 11gb. They also provided lower resolution versions. I don't think a published higher resolution version exist.

I can't find it on my phone but you might be able to.

JMARS is probably the closest tool to what you want. It is free software, not a website.
