Serving State DOTs

Surdex has provided mapping services to state Departments of Transportation (DOTs) and other state transportation entities since 1954. The datasets requested by DOTs have evolved, from film imagery (which is very rarely used) to high-resolution orthoimagery and lidar derivatives in various digital formats. Planimetric mapping data formats have drastically changed as well. This data facilitates more precise planning for roadway repairs and improvements, including bridge and interchange projects. Many states maintain lists of prequalified contractors, which enables them to request geospatial data as needed rather than losing valuable time to the Request for Proposal or Request for Qualifications (RFP/RFQ) processes for each project. Surdex is prequalified in several states, and we have completed recent projects for many of them, including numerous task orders for the Illinois, Iowa and North Carolina DOTs.
