A topographic survey is normally performed by a small group of geologists together with the goal of producing two-dimensional charts which stand for three-dimensional elements of the landscape. The functions commonly included are both natural and man-created things, including mountains, lakes, trees and shrubs, dams, properties and streets. These diagrams are also known as relief charts.

The cartographers use contour lines, emblems and colors as representations for various land factors, such as elevation and depressions. The line, polygon and level would be the three primary symbols included in topographical diagrams. Small buildings including properties are displayed by dots. Straight, curved and dotted collections are used to depict linear products including highways, railways and rivers. Broad expanses of water are usually mentioned by blues, thick jungles with green veggies.
Contoured facial lines spaced apart at specific time intervals may be used to demonstrate distinct ski slopes, serious trenches and tall mountain tops. The greater number of closely spaced lines signify large mountains, whilst widely spaced facial lines denote delicate ski slopes.
There are several methods used during the roll-out of relief diagrams. The primary inspection of the site has been a steady practice ever since the very first identified topographical chart came to be by america Geological Service in 1876. Browsing sites can offer the map-making crews with important confirmable data factors.
Ever since the 1940s, aerial reports have also presented beneficial resources to cartographic crews. The development of the ability to take photographs from airplanes and copters helps develop the detail and accuracy and reliability of relief charts.
