Service
Precision elevation data and contour mapping that forms the foundation of every engineering, drainage, and site development project. We capture ground truth — exact elevations, terrain features, and surface geometry — so your engineers can design with confidence from the first submission.
A topographic survey measures and maps the elevation and physical features of a site — including terrain contours, drainage patterns, existing structures, trees, utilities, and other surface improvements. The result is a highly accurate 2D or 3D representation of the land that engineers, architects, and contractors use to plan, design, and permit development projects.
EA Mapping performs topographic surveys using high-precision GNSS receivers, robotic total stations, and UAV-based photogrammetry, delivering data in formats ready for Civil 3D, Bentley, and GIS platforms.
LiDAR-derived DTM with contour overlay — typical deliverable for drainage and grading design.
