I've been playing around with public LIDAR derived digital elevation
maps. On the left a plain DEM isosurface with a green color. On the
right, an image using the AOI pattern of 3.7 to highlight relatively
flat areas. The method works well. A thank you to the development team
for adding the AOI pattern to 3.7.

Good application, William. Elevation data + POV-Ray = good times.
Have you tried using a proximity pattern for that yet?

Hi Sam,
Yep, it's fun.
No, I have not tried a proximity pattern. That's a great idea for
pulling out ditches, gullies and such. Thanks!
I expect GIS professionals have custom tools for interpreting elevation
data, but, finding quite a lot can be done within POV-Ray itself.

An isosurface from a DEM?!? Does it follow Earth's curvature or is it
simply a flat "heightfield"? Could you render any surface vistas in
"pedestrian view"?
See you in Khyberspace!

Hi Yadgar,
No, the images do not follow the Earth's curvature. The elevation data
as provided by the state government here is set up as "flat" tiles which
can be stitched together.
I haven't tried pedestrian views having gotten distracted by other
things, but it is on my list to do. I have the idea to do it in
combination with the SkySim macro for the sun & sky on some give day at
my position just to see if things match up!
