Land surveyors typically conduct a topographic survey starting with the establishment of vertical and horizontal controls, which will become the survey’s framework. From there, they will determine ample horizontal location and the elevation of ground points for data plotting as the map is being prepared. Part of determining a land’s geographic condition is locating man-made and natural features in the land, but this aspect can be optional, depending on the survey’s purpose. The computation of angles, distances, elevations, and volumes of earthwork are critical aspects of the topographic survey before the topographic maps are drawn.
The outcome of a topographic survey can reveal many different details about the land. The information will be collated and analyzed to determine the value, life, and strength of the land. The survey will provide accurate measurements on the breadth, dimensions, and length of the land, as well as its curves, elevations, and height. All surveyed aspects will contribute to the contouring and mapping of the land, making the topographic survey useful when examining the configuration of the cultural and natural features of the property and the land.
