The Influence Of Map Scale On Engineering Geologic Mapping


Various engineering geologic maps ranging from statewide to local site studies have been developed during recent years in Missouri for land-use planning purposes. Because this work has been initiated at the request of and with the support of various regional planning agencies, the scope and content of these maps has varied greatly. Several engineering geologic maps, considered most representative of mapping procedures used in Missouri have been compared with respect to cost (man-hours of effort); scope, from the viewpoint of mapping detail, definable mapping units, and thoroughness of aerial coverage; and, application or potential use of the map by the non-geologist. Map scales vary from 1 : 24 000 to 1 : 250 000 and aerial coverages range from 163 square kilometers to 2 400 square kilometers. The potential application or usefulness of these maps have been evaluated in an attempt to determine a concept of cost to benefit ratios. No specific recommendations defining the "best" approach to this type of mapping can be made since each situation is unique. However, some guidelines and observations regarding the potential return for a given investment in engineering geologic mapping are presented. © 1976 International Association of Engineering Geology.
