TransportationEngineers face several challenges in accessing highly accurate features needed for use in transportation infrastructure design calculations such as volumes, offsets, etc. While these features are normally accessed through an extensive ground survey and/or through photogrammetry, these methods introduce challenges in terms of time, cost, access limitations and traffic, as well as in the level of detail and accuracy, especially in areas covered by vegetation canopies. Terra has developed a suite of comprehensive solutions to these challenges, specifically designed for transportation engineering applications.
