A TECHNIQUE OF MORPHOLOGICAL MAPPING1
R. A. G. Savigear · Annals of the Association of American Geographers · 1965
The technique is based on the assumption that the plane and curved surfaces (facets and segments) of the ground surface adjoin in discontinuities (breaks of slope and inflections) whose characteristics may be recognized, measured, and mapped. The minimum sizes of the lines, symbols, and arrows and figures that can be drawn clearly on a map in the field to represent these land forms are one-fiftieth, one-sixteenth, and one-eighth of an inch, respectively. These assumptions and the scale of the map selected for field mapping are used to define the minimum ground-horizontal equivalents of the morphological units, micro-units, and discontinuities that can be represented at that scale. The technique is applied most successfully at scales of approximately 1/7,000 to 1/10,000 but may be used to give a satisfactory representation of morphology at scales down to approximately 1/75,000.
