Land surveying is an old discipline — the ancient Egyptian’s squared off the Pyramids with mathematics, triangulation was developed in the 1600s and several early American presidents, including Washington, were surveyors before they led the free world. The U.S. Air Force created Global Positioning System in 1978, and Dungan Engineering began trueing Mississippi in 1992.
Since then, we’ve gathered information for NASA’s John C. Stennis Space Center, the Mississippi Department of Transportation, numerous electric power associations, counties and municipalities, contractors, developers and private citizens, producing every method of surveying product, including boundary, topographic, lidar, right-of-way plats, ALTA surveys, as-built surveys, construction layouts, orthomosaic imagery, GPS and GIS systems.
Dungan still follows the ancient principles of land surveying, but our gear is more on the Air Force side of things. Our surveyors deploy state-of-the-art software and technology, integrating the time-proven methods of data collection with the highest-level equipment in order to achieve pinpoint accuracy in mapping and data collection. Our specialists use Trimble dual frequency RTK units, so our projects have connectivity with the National Spatial Reference Framework using the NGS Online Positioning User Servicer (OPUS) and Local NGS Control, allowing real-time positioning in the field. The company operates an Unmanned Air System to create high-quality Orthomosaic aerial photos and digital terrain models. Additionally, our usage of Second Order Topcon digital levels assures quality elevation control on every project.
