planimetric map

planimetric map

(Data West Research Agency definition: see GIS glossary.) A map showing only the horizontal position of features on the Earth's surface which show geographic objects, natural and cultural physical features, and entities without topographic features such as roads, buildings, and water bodies that are visible and identifiable on aerial photographs, but which can be compiled into map features through photogrammetric or surveying procedures. A planimetrically accurate map showing planimetric detail and other general features shows accurate horizontal distances between features.

Map features show roadway feature details as roads, sidewalks, streets, highways and alleys including curb lines, edge of paved surfaces or edge of traveled way, and general feature details as building footprints, reservoirs, tanks, docks, piers, airports, bridges, overpasses, underpasses, railroads, parking lots, driveways, other impervious surfaces, streams, lakes, drainage courses, holding basins, shorelines, other watercourses, vegetation outlines, elevations, fence lines, drainage, and other similar construction or terrain features.
