Author Description

In recent years, Lidar technology has improved. Additionally, the experiences of state departments of transportation (DOTs) with Lidar have grown, and documentation of existing practices, business uses, and needs would now benefit state DOTs' efforts. NCHRP Synthesis 642: Practices for Collecting, Managing, and Using Light Detection and Ranging Data, from TRB's National Cooperative Highway Research Program, documents state DOTs' practices related to technical, administrative, policy, and other aspects of collecting, managing, and using Lidar data to support current and future practices.
