Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the landforms and features themselves, or a description or depiction in maps.

Topographic maps became a signature product of the USGS because the public found them - then and now - to be a critical and versatile tool for viewing the nation's vast landscape. Current US Topos and historical topographic maps are available as digital files or printed to order.

The meaning of TOPOGRAPHY is the art or practice of graphic delineation in detail usually on maps or charts of natural and man-made features of a place or region especially in a way to show their relative positions and elevations.

Topography is the study of the land surface. In particular, it lays the underlying foundation of a landscape. For example, topography refers to mountains, valleys, rivers, or craters on the surface. The origin of topography comes from “topo” for “place” and “graphia” for “writing”.
