Information about the geographical condition of a land is important when identifying the map and contours of the land. A topographic survey is necessary to identify the map and contours of the land, and it is conducted at the planning stage of construction and developmental projects. The results of a topographic survey will serve as the project’s base map regardless of the type of structure that will be built. Hence, the survey is a versatile service that can be ordered for a residential project, bridge or road construction, commercial structure, and other types of developmental structures.
The topographic survey typically begins by establishing the vertical and horizontal control, which will be the framework. From there, the elevation and horizontal location of ground points are determined to ensure that there is enough data for plotting when preparing the map. The survey will then pinpoint the man-made and natural features before distances, volumes, elevations, and volumes of earthwork are computed. The final step to a topographic survey is the creation of the topographic maps.
Every aspect of the land that is found in a topographic survey will contribute to the contours of the land, and the information will be used in determining the cultural and natural features of the land. Hence, topographic surveys are useful to land promoters, geologists, engineers, architects, foresters, and government agencies.
A topographic survey is conducted below and above ground level. It examines areas and every single element or material found in the land, such as walkways, trees, manholes, walls, wells, utility poles, and soil density. In a topographic survey, every material found on the land contributes to the outcome and the results. That way, you can be sure that all important details about the land can be collected to analyze its value, life, and strength. Measurements on the dimensions, breadth, length, elevation, curves, and height of the land must be accurate.
