The Surveys Division uses highly technical field survey instruments, Global Positioning System (GPS), aerial photography, aerial mapping, photo scanners, computers and Computer-Aided Drafting and Design Systems (CADD) workstations to obtain and compile physical land features. Digital Terrain Modeling (DTM) computer software is then used to provide information for location and design of roadways and bridges. Land surveys are performed for preparation of legal descriptions and survey plats on land acquired by the AHTD.
