A topographic survey is a detailed map of the natural and manmade features on a piece of land. It shows elevation changes, structures, drainage paths, utilities, trees, and other site characteristics. H&M Surveying uses high-precision GPS, UAS based Lidar and Photogrammetry, as well as cutting edge robotic total stations to create accurate topographic maps used for site planning, engineering, and permitting.

You typically need a topographic survey when planning new construction, grading or drainage improvements, utility installations, roadways, or site development. It’s often required by engineers, architects, and local permitting agencies to ensure your design fits the terrain and avoids costly surprises.
