Since our inception in 1954, Surdex has played a key role in supplying engineering and architectural firms with superior imagery and highly accurate mapping products. These firms perform work for the private sector as well as local, county, state and federal government, primarily for construction and development projects. Projects often include image acquisition, digital orthoimagery, planimetric mapping, topographic mapping, LiDAR and volumetric inventory services.The prime contractors use our products to develop facilities, manage infrastructure, landfills, water and wastewater systems, as well as roadways, airports and railroads (see Transportation projects); and pipelines and utility lines (see Energy / Utility projects).
