A topographic survey is usually performed by a team of geologists with all the goal of producing two-dimensional maps which stand for three-dimensional elements of the landscape. The functions commonly provided both are natural and guy-made items, for example mountains, ponds, bushes, dams, complexes and roads. These diagrams are also called relief charts.

The cartographers use shape facial lines, icons and colors as representations for many different land components, such as height and depressions. The fishing line, polygon and point are the three main signs integrated into topographical diagrams. Small components such as properties are displayed by dots. Straight, curved and dotted outlines are used to reflect linear products including streets, railways and estuaries and rivers. Large expanses of water are usually suggested by blues, packed forests with vegetables.
Contoured lines spread out apart at specific durations may be used to demonstrate well-defined slopes, deeply trenches and large mountains. The greater number of closely spaced outlines symbolize high hillsides, while widely spread out facial lines denote gentle ski slopes.
There are numerous methods applied during the creation of relief diagrams. The direct inspection of any site is a huge consistent process since the earliest acknowledged topographical map was developed by america Geological Service in 1876. Visiting sites offers the guide-making squads with crucial confirmable data details.
Considering that the 1940s, aerial research has also supplied important assets to cartographic crews. The development of the capability to get photos from planes and helis helps increase the details and accuracy of relief charts.
