1. Engineering geologic maps in the United States may be one map prepared as part of a larger study of environmental geology, individual areal geologic maps containing additional engineering geologic data, or engineering geologic maps of single construction sites.
2. No systematic methodology for engineering geologic or environmental geologic maps has been developed.
3. Environmental geology studies combine the efforts of workers in a number of geologic fields to produce many maps of basic data, as well as various interpretative maps, only one of which may be an engineering geologic or foundation conditions map. Maps of many scales may be prepared for a single study, depending upon the geologic conditions, the main problems of the area, and the principal needs.
4. New technology, including computers and various types of aerial photography, is constantly being developed, and its use is being encouraged to increase the speed and efficiency of map preparation.
5. The use of engineering geologic and environmental geologic maps in the United States is constantly growing; such maps will continue to be made in increasing numbers.
