So uh, i have a few questions.
1) Is there a website where you can find greyscale heightmaps (like this one:
) but for specific locations, and/or more importantly, not in an equirectangular projection? Even if it's a non equirectangular world map it's ok
2) Can you do this with Arcgis or Qgis? Can you download elevation data and make a grey scale heighmap from it?
3) Is there a way to change the projection of a high quality worldmap? I know about G Projector but it only goes up to 7500 * 3500 px, is there a software that can do it for much larger maps (20,000 px large or more)?
Thanks for your answers.
