Launching at NACIS, which is next week, but available on the Mac App Store now, Eduard is a Mac-only application that generates relief maps by “[using] machine learning to match the aesthetics and details of relief shadings created by Swiss cartographers.” (The name is a pretty obvious reference to Eduard Imhof.) The app allows you to adjust direction of illumination, aerial perspective and detail, and works with digital elevation models and a number of file formats. The launch price is US$69.99 (C$99.99) until the 23rd, after which I presume the price will go up.
