These methods include satellite images, images taken from aeroplanes, helicopters, radar, and sonar (underwater). Topographic maps show the three-dimensional surface of the earth in two dimensions using elevation-contour lines.

Direct survey –Ī direct survey is when a topographer on ground, uses surveying equipment, to measure the location and elevation of the land. There are mainly two primary methods of surveying the landforms – direct survey and indirect survey.

The entire series is available as a free individual map download as GeoPDF. Topographic maps use a particular type of line, known as a contour line, to depict different elevations on a map. DCS Spatial Services have released an updated GeoPDF Topographic Map series, which are available from the Spatial Collaboration Portal. There are some maps that show different physical features of the Earth.

Mapping is a crucial part of earth science and are wonderful tools that help us find our way in a street, in a city, in a country, in fact, anywhere on the Earth. Topography is a combination of two Greek words ‘topos’ meaning ‘place’ and ‘graphein’ meaning ‘to write.’ It is extremely important to chart and predict weathers, lay roads and plan other transportation means, to plan architectural constructions, study geology, farming, water body management etc. Every point on a particular contour line is at the same elevation. This page shows the elevation/altitude information of United States, including elevation map, topographic map, narometric pressure, longitude and latitude. Where does the word topography originate from? The topography is represented by contour lines, which are imaginary lines. This tool allows you to look up elevation data by searching address or clicking on a live google map. Manmade features such as roads, dams, and cities may also be included. These features typically include natural formations such as mountains, rivers, lakes, and valleys, forests, glaciers etc. Topography is the study of shape and features on the surface of the Earth.
