Survey + Geospatial

Beyond measure…

The expertise to capture the information you need

CEC’s surveyors and geospatial specialists collaborate with engineering and environmental professionals to streamline the design, permitting, and construction processes by capturing data via land, water, and air. (And we still use tape measures, too!) Our experienced licensed Professional Land Surveyors, FAA-licensed and certified unmanned aerial vehicle (UAV) pilots, terrestrial and mobile LiDAR specialists, and bathymetric/hydrographic surveyors can provide topographic, boundary, construction, hydrographic, scanning, and aerial surveys in 3D and 2D formats. Our full complement of technology includes ultra-high-resolution and 360-degree digital cameras, survey-grade GPS units, and watercraft equipped with sonar equipment.
