Topographic Surveys are used to identify and map the contours of the ground along existing features of the earth’s surface. For example, trees, buildings, streets, walkways, manholes, utility poles, retaining walls. In case that the purpose of the survey is to serve as a base map for the design of a residence or building of some type, or design a road or driveway, it may be necessary to show perimeter boundary lines and the lines of easements on or crossing the property being surveyed, in order for a designer to accurately show zoning and other agency required setbacks.
These surveys require “benchmarks” to which ground contours are related, information regarding surface and underground utilities, determination of required setbacks, etc.
- Produce topographic maps
- Construct topographic (cross-sectional) profiles
- Establish vertical and horizontal control for accurately defining locations
- Create topographic surface files to do cut and fill data
The first stage of surveying is always to establish horizontal and vertical control. Such as the distance, direction and difference in elevation between key fixed points. Then, you establish a survey plan that includes checks on accuracy. Some of these checks are: redundant points, pacing of measured distances, surveying between fixed positions among many others.
Topographic surveys depict contours of a property along with the location of all known features on, above and below the ground.
Topographic surveys are generally used as base maps for the designing of buildings, roads and new subdivisions.
Reliable horizontal and vertical control is established in a safe location near the project area. We use modern up-to-date RTK GPS and Robotic Total Station equipment in order to ensure reliable data capture.
