Abstract: Topographic maps provide a vital inventory of man's physical environment. A vast effort is required to acquire this inventory and keep it up to date. To meet the burgeoning demand for maps, several approaches can be considered: increased expenditures for mapping, concentration on new mapping, concentration on map revision, or development of better techniques. The only feasible approach today is improvement of techniques. Several avenues for advancing map technology are cited, such as the use of airborne electronic systems for field surveys, the application of new photogrammetric systems for control extension and map compilation, the automation of various cartographic operations and the establishment of computer shortcuts. The orthophotomap is cited as a new kind of map presentation that gives a better inventory of certain environmental situations. To solve the mapping problem in rapidly changing areas, a new interim-revision system provides a means of updating maps at greatly reduced cost. Mapping science is dynamic and is producing new ways to maintain the inventory for a dynamic environment.
