Use of Lidar for Surveying and Mapping Applications

Cosponsored by the New Hampshire Land Surveyors Association

1.5 CEUs for Surveyors

Lidar in surveying can have static, mobile (vehicle), or airborne applications. Integrated primarily with GPS-IMU, it can provide survey-quality, 3-D coordinate results, along with an intensity return that is often converted to a conventional image via integrated photography. Current technology enables the capture of an outstanding 1.5 million measurements per second. This seminar will discuss data capture, freeware office viewing, limited processing of 3-D models, and cost effective software strategies for some forms of feature extraction based on elevation change. Integration of lidar data with other raster and vector-based formats will be presented. The use and quality assurance of the available free lidar data in New England will be presented.
