Height Modernization and Continuous Operating Reference Stations in Pennsylvania

The Pennsylvania Department of Transportation (PennDOT) has advanced its height modernization initiatives, enhancing survey accuracy and efficiency. With over 130 Continuous Operating Reference Stations (CORS) and extensive aerial photography since 1968, the program supports various applications, such as floodplain mapping, urban planning, and transportation mapping. By reducing field survey costs and standardizing height data, PennDOT ensures better reliability and accessibility for regional needs. Join us in exploring the significance of height modernization in improving Pennsylvania's survey infrastructure.
