Terrain-Emboss, Its Application to Shaded Relief Production by Relief Model Photography

摘要

A simplified hand-tooling technique for model making has for some years been under development at the Aeronautical Chart and Information Center for the primary purpose of improving production of shaded relief portrayal on USAF charts. Basic concepts, some of the tests made, problems experienced which preceded adaptation of Terrain-Emboss to shaded relief portrayal, and an evaluation of the technique as compared to present hand-airbrush and other known model-making methods, are discussed.
