Geospatial extraction of bridge data from USGS Entwine point clouds

tx-bridge logo

Description: From entwine point cloud data served by the USGS 3DEP service, extract geospatial data from points classified as bridges over a requested goegraphical area. These scripts were developed to get bridge limits such that they can be used to build a terrain that is a composite of the 'bare-earth' and the bridge deck data (healed terrain). As a flood mapping surface, this 'healed surface would be used to determine when bridges are overtopped during a flood.
