Land form analysis from topographic maps

The paper suggests and illustrates several techniques useful for analysis of land form characteristics from topographic maps. Five maps representing distinctly-different types of terrain are analyzed numerically, and the results are presented in map form. The analysis is based on indices derived from values of contour lines, and the indices are selected according to the salient characteristics of the terrain in a given area. Stream eroded, glacial, aeolian and structurally controlled types of terrain are analyzed to illustrate the variety of approaches necessary for analysis of land form from topographic maps.
