The maps that I introduced last month at the ICA Mountain Cartography Workshop in Banff are now available online in screen-viewable and print versions. One map is of Canyonlands National Park, Utah, and the other is of Glacier National Park, Montana. They both feature rock textures rendered with Texture Terrain Shader software. Working on these was a lot of fun.

Awesome work, as always Tom. I really love the Glacier one and I can imagine you had fun making it.

Incredible looking terrains. I just finished working with TTS for the first time on a small map of Yosemite Valley, I really like what it adds to the NSD relief. Thanks for posting your tutorial on its use.

Great work Tom.
I am working on a similar technique. When I accomplish it i will try to describe it
Best regards

These maps are truly great works of art (even if they are analytically made)!

 

What is the resolution of the original DEM?

 

I'm trying the same with 10m DEM, but it's seems that the reslution of the DEM is to coarse to get the hatchures right.

Hi Agnar,

 

Thanks for your kind words about my maps that I made with standard 10m DEMs from the USGS. Have you tried replicating the rock texture procedure outlined on the linked page below?

If that doesn't work, I can share my source file with you next week when I return from traveling and have access to it back at the office.

Hi Agnar,

 

To follow up, the original DEMs were indeed at 10-meter resolution, although I rendered the relief images to almost double that size. For example, I rendered the Canyonlands DEM that contains 4,879 x 6,725 height samples as relief images measuring 8,616 x 11,876 pixels. You can download my original Canyonlands NSD file (it will open in TTS) here.

Hello

perhaps I can help a little.

Indeed Tom's method work, but you have to use a high resolution dem. An render it at very high resolution in 3D Nature.

Another approach, if you have a good dem, and a program to make dem calculus, is to calculate the curvature and export it as an image (greyscale)

The rest of the process is the same as described by Tom.
