Isle of Mull
I've created a isometric like image of the Isle of Mull in Scotland with GIMP, G'mic and Inkscape for a photo book: I used Gimp 2.9.9 with the new HGT file import and the height maps from the NASA. You can read more about it here: https://dablogter.blogspot.de/2018/01/gimp-now-supports-hgt-file-format.html G'mics 3D elevation plugin: Water texture from here: https://www.roblox.com/library/31952856/Water-Texture-FREE The land colours are from a blurred screenshot from Google Earth. Inkscape for the markers: The sun is the standard "Sparks" brush from GIMP. Cloud and bird brushes from https://www.deviantart.com https://para-vine.deviantart.com/art/Cloud-Brushes-152820554 https://wingsofahero.deviantart.com/art/Bird-Brushes-119021426 https://wingsofahero.deviantart.com/art/Flying-Bird-Brushes-116541763 And a lot of fine tuning in GIMP, here is a screenshot of the layers dialogue:
