The Functions Of A Topographic Survey

A topographic survey is normally performed by a band of geologists with the purpose of producing two-dimensional maps which represent three-dimensional the different parts of the landscape. The features commonly included are both natural and man-made objects, such as for example mountains, lakes, trees, dams, buildings and roads. These diagrams are also known as relief maps.

The cartographers use contour lines, symbols and colors as representations for different land elements, including elevation and depressions. The line, polygon and point are the three main symbols incorporated into topographical diagrams. Small structures such as buildings are represented by dots. Straight, curved and dotted lines are accustomed to depict linear items such as for example roads, railways and rivers.  Topographic Surveyors Henley-in-Arden  of water are often indicated by blues, dense forests with greens.

Contoured lines spaced apart at specific intervals can be utilized to illustrate sharp slopes, deep trenches and tall mountains. The more closely spaced lines symbolize steep hills, while widely spaced lines denote gentle slopes.

There are lots of methods used during the creation of relief diagrams. The direct inspection of a site is a consistent practice since the earliest recognised topographical map was created by america Geological Service in 1876.

Since the 1940s, aerial studies also have provided valuable resources to cartographic teams. The development of the opportunity to take photographs from airplanes and helicopters has helped expand the detail and accuracy of relief charts.

Campers, engineers, hikers, students and others can have the advantage of exploring the natural and artificial land features of areas without being necessary to visit the sites personally. Among other uses, usage of landscape details can be helpful when planning vacations, analyzing weather patterns or considering construction projects.
