Traditional property surveys only show two-dimensional aspects of the land. While this may be useful for certain aspects of construction projects, others demand a more in-depth look at a property. Topographic surveys are required when additional attributes of the land need to be considered. Find out more about what these unique renderings entail below.

What Is a Topographic Survey?

Topographic surveys are representations of both natural and manmade structures on a property.

Traditional surveys typically include buildings, fences, and similar features, but topographic drawings incorporate streams, trees, and other elements of the land which could impact the course of a project.

Vegetation and other attributes such as brushy or wooded areas are identified and recorded on these renderings. They may also show utility features, such as pipeline markers, electric boxes, and street lights. In addition, topographic renderings can incorporate contour lines. These features show the elevation of the land, including its peaks and valleys.

The surveyors usually use Electronic Distance Metering (EDM), Global Positioning System (GPS), and magnetic compasses. There are different methods, from traverse to radiating; which one is best will depend on the characteristics of the area in question. 

What Is It Used For?

Oftentimes, topographic surveys are consulted by builders, utility workers, and land owners before making major changes to a property. They are referenced before new construction can begin and prior to grading or drainage products being installed.

Enhancements to existing structures may also call for topographic assessments. For both residential and commercial projects, the surveys are often used before utility design, such as sewer installations. Engineers also use them before designing roads and bridges.
