Quote from: WAS on November 04, 2021, 12:20:22 AMHave you tried checking "auto georeference from file"? When it's unchecked your map will be at 0,0,0 or whatever location settings are manually supplied.

At least in my head. Maybe the coordinates systems aren't what they state they are? Maybe you can use one of the online conversion tools and convert them all to the same metric and system?

Quote from: Roberts on November 05, 2021, 05:28:55 PMLooking at your screenshot it also seems strange that the DEM and the image map has the same corner coordinates. Since the image map covers a much smaller area, it should not have the same corner coordinates as the larger DEM. I will try to have a look at this, perhaps download the same image of the crater as you and see if I can match it with the DEM/heightfield. Not at the computer right now though. Robert
Quote from: terp on November 05, 2021, 06:16:38 PMThanks again for your help, Robert!If you're referrring to the screenshot in my latest post, the values are exactly the same because I'm importing the same colormap twice.The screenshot shows the results of the same colormap used in a Geog heightfield Load node and Geog Image Shader Map.I wanted to see if TG4 would move the image to the right spot if I used it as heightfield instead of an image.The heightfield node seemingly moved the image to the correct spot, where the Geog Image Map Shader does not.
