About the research

Conventional photogrammetric methods are frequently used to create surface terrain models for roadway planning and design. An advanced remote sensing technology LIDAR (Light Detecting and Ranging) has become a feasible, commercially available alternative for collection of coordinates for creation of surface terrain models. This project intends to compare surface elevation data from LIDAR to that obtained from traditional photogrammetry for use in highway location and design. The study location is a 10 mile stretch of Iowa 1. The project will compare spatial accuracy, data quality, and cost for the two data collection methods.
