Course Description

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.
