A topographic survey is usually performed by a group of geologists together with the goal of generating two-dimensional maps which represent three-dimensional components on the landscape. The capabilities usually integrated are each all-natural and man-made objects, such as mountains, lakes, trees, dams, buildings and roads. These diagrams are also referred to as relief maps.

The cartographers use contour lines, symbols and colors as representations for distinctive land elements, including elevation and depressions. The line, polygon and point are the 3 main symbols incorporated into topographical diagrams. Modest structures including buildings are represented by dots. Straight, curved and dotted lines are used to depict linear items which include roads, railways and rivers. Wide expanses of water are generally indicated by blues, dense forests with greens.
Contoured lines spaced apart at precise intervals is often utilized to illustrate sharp slopes, deep trenches and tall mountains. The far more closely spaced lines symbolize steep hills, when extensively spaced lines denote gentle slopes.
There are several solutions used through the creation of relief diagrams. The direct inspection of a site has been a consistent practice because the earliest recognized topographical map was created by the United states of america Geological Service in 1876. Visiting sites can supply the map-making teams with significant confirmable information points.
Since the 1940s, aerial studies have also offered beneficial resources to cartographic teams. The development of the potential to take photographs from airplanes and helicopters has helped expand the detail and accuracy of relief charts.
An effective topographic survey can result in the creation of incredibly beneficial pamphlets. Campers, engineers, hikers, students and other people can have the advantage of exploring the natural and artificial land attributes of regions devoid of getting essential to pay a visit to the sites in individual. Among other uses, access to landscape particulars could be valuable when planning vacations, analyzing climate patterns or thinking of building projects.
