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

Landforms on topographic maps depict land-based structures such as hills, mountains, valleys, ridges and more. The most important information conveyed about landforms is the elevation and relief. The elevation represents the landform's height or distance from sea level. The relief shows the landform's relative shape.

Answer and Explanation: Because topographic maps show elevation changes an architect can use one to locate an ideal spot to place their planned construction. An example of this would be planning a parking lot. Ideally an architect would choose a location with no, or little change, in elevation.

Contour intervals reveal how much vertical distance there is between each contour line. Closely spaced contour lines indicate very steep slopes. Contour lines that are sharply tapered indicate an uphill direction. Rounded contour lines typically indicate a downhill direction.

What is the contour interval of the topographic? Explanation: A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A contour interval is the vertical distance or difference in elevation between contour lines.

Site topography can be defined as the study of the shape, landforms and other physical features of the site under consideration. This study is a part of the geotechnical investigation carried out prior to undertaking a trenchless pipeline installation project.

The five descriptors explained are elevation of the low and high stations, altitudinal amplitude, valley (low station), and hump (high station).
