Topographic Survey
A Topographic Survey is a survey that gathers data about the elevation of points on a piece of land and presents them as contour lines on a plot. The purpose of a topographic survey is to collect survey data about the natural and man-made features of the land, as well as its elevations. Topographic maps are used to show elevations and grading features for architects, engineers, and building contractors.
KRISH ENTERPRISES professional land surveying team is well-versed in the nuances of topographic surveying. Utilizing the latest surveying technology, KRISH ENTERPRISES land surveyors produce accurate, consistently reliable topographic surveys, saving you both time and money during the construction process.
Topographic surveys utilize three main methods, and are often a mix of all three as each method has a different strength:
- UAV Photogrammetry and LIDAR are used to determine the surface contours of large areas, but may not map features.
- GPS: GPS allows for quick mapping of open areas that are not large enough to justify Aerial methods.
Total Stations: A field crew is on site and directly maps each feature. Utilized when tree cover prevents other technologies, or when the highest levels of accuracy are required.
