I particularly enjoy the “old-school” 3D maps.
- Get the altitude data for the area you want to work with. Pretty sure I had to make an account at the usgs.gov page. They had a peculiar web app where I was able to query locations and download the data. The data came in lots of formats, the one I managed to import into photoshop was an ultra high rez TIFF iirc.
- Optionally convert the grey scale height map into a normal map. I did this with nvidia's tool. I think normal maps made my results look better (probably at the cost of some accuracy, idk. You get more bytes of data using the whole color space, so it's probably better)
- Import the normal map into 3d modeling software. I used blender.
- Set a super sub divided plane's displacement map to the image you created. Dick with the z-axis scaling until it's sufficiently accurate / inaccurate for what you're trying to do.
- Render? Pull back into photoshop? Draw your annotations? You can mess with levels of your original height map (control+L) if you want particular altitudes masked out for coloring water or something. There's about a trillion things you can do from where. In the 3d world, I'm a huge fan of tri-planar materials.
hints at processing, qgis and blender
To have presented cartographically accurate, factual information + aesthetic creativity would be so much more beautiful.
I see this in art where the beauty of the piece is "shallow" - i.e., aesthetic. The other end of this spectrum is conceptual art and the whole dada thing; beauty here is conceptual. When an art piece combines both, it makes the hair on the back of your neck stand up (for e.g. Francis Bacon's paintings). The more you try to find out about the piece, the more you get "sucked" into the abyss of its beauty.
It's one thing to dislike the work linked to the original post, but something else altogether to indulge yourself by wheeling out a bogus, trivial and pretentious personal theory of art. As has been noted before, claiming expertise in areas about which one knows nothing is a very HN characteristic.
