Vue, that is one of the tools I use to render 3D images with, have finally included isometric camera projection. Been waiting for a proper 3D rendering tool that could do terrains the way I need and also have the Isometric camera projection. This is one of the easiest ways to show as 3D landscape as a 2D image and get a good sense of the topography, even over a large area.

Couldn't resist the temptation to try it out, and here are my first results. 

The resolution is about 100 ft per pixel and my initial reaction is that this is very promising!
It renders very quickly and it looks good, and gives a good sense of the landscape.

Considering that these images are a first test that only uses a highmap and a simple texture as material, and still comes across as OK, means that this has great potential. With a proper material setup and forest material, PBR and specular map, bumps etc this can hopefully look really good. 

It is also easy to merge rendered bits to cover a large area, which makes it something to look into for future setting maps. It will be a good variat in the mapping bag of tricks.

A detailed blog post will come when I know a bit more of what I'm doing and have read the manual!
