Representation of relief types in geomorphological mapping of a glaciated shield area (Finland)

Abstract

According to modern conceptions, the geomorphological map consists of several superposed informational layers. The IGU Commission on Geo­morphological Survey and Mapping suggests the fundamental layer, apart from the topographical base, to be a representation of relief types dis­cerned on the basis of either morphostructure or morphogenesis as a function of morphometrical variables. The relief‑type representation methods of the small‑scale, medium‑scale and large‑scale legends recom­mended by the Commission were applied to an area in south Finland. The application involved a few slight revisions of the legends. With these changes, the tested relief‑type representation methods appeared suitable as a base for geomorphological maps of glaciated shield areas. The other informational layers have not been discussed in the paper.
