Description:

LIDAR is the latest in field data collection technology. Instead of holding a prism at every point, LIDAR sensors spray light beams to all objects in its field of view to collect point data at a desired interval (as little as every few millimeters). This creates a "point cloud" with xyz measurements on every point in the cloud. The point clouds are reconciled with digital photos, and the result is a color 3D model of the project site. We can then choose from a variety of renderings and choose which points and linework will be added to CAD drawings and DTM's. GdB utilizes a variety of LIDAR techniques. GdB technicians extract the desired data from the point clouds to address your specific project requirements. Stationary LIDAR - The laser scanner is set up on a fixed point tripod that does not move during data collection. GdB uses Stationary LiDAR in high traffic areas where we wouldn't want to send a crew member, for surveying details of structures such as bridges and building faces, and indoors to capture piping, structure, tunnels, walls, etc. Aerial LIDAR - The scanner is mounted on the bottom of an aircraft. GdB utilized Aerial LIDAR to collect topographic data of Rockaway Beach for the reconstruction of the boardwalk that was destroyed by Superstorm Sandy. Mobile LIDAR - The scanner is mounted on top of a vehicle and collects data as it drives at speeds up to 60mph. The sensor collects up to 1.2 million points per second. GdB utilizes Mobile LIDAR on a variety of roadway projects for New York City and other municipalities.
