Types of Topographical Surveys
There are more than one type of topographical survey, depending on the purpose of the survey and the desired output. These are; general land survey, boundary survey, and construction surveys.
General Land Surveys
Land surveys are for determining distances and angles between points on the land, and is essential for civil engineering and construction projects. Land surveys determine the three-dimensional positions of points and the distances and angles between them.
Boundary surveys are used to identify a property’s boundary lines and are used as a means of formally defining the limits of properties. This is an essential part of property ownership. If boundary lines are contradictory, landowners may need to carry out a boundary survey.
Boundary surveys are usually carried out prior to the purchase of land, and include the measurements of the land.
A construction survey is much like a land survey and involves looking at the natural habitat of the area. This survey is concerned with the layout of the project and involve markers and reference points on the site that instruct contractors where to start building a new structure.
