Airborne lidar technology is widely accepted among transportation companies as an efficient tool for acquiring geo-referenced spatial data for various applications essential to transportation route design, expanding of current design.
New route design can take the fundamental advantages of the lidar workflow which is all-digital format of its data collection, processing, analysis, delivery, and storage steps. By integrating high accuracy point cloud data and imageries with transportation GIS software workflow, it optimizes the route selection, cross section, data transfer, it realizes a seamless work flow from survey , designing, construction to transfer the asset to operation management. This maximizes the efficiency of the entire workflow, effectively avoiding duplication, saving investment. Furthermore, digital data acquired during an initial lidar survey can be archived and used to form the foundation of a permanently searchable and editable database, allowing subsequent time-based studies such as change detection.
