Using USGS/ASPRS Data Quality Measure (DM) Software for V...
This workshop provides an in-depth look at the USGS/ASPRS Data Quality Measure (DQM) software. DQM provides an ability to determine the relative accuracy, or geometric quality, of overlapping swaths of lidar point clouds using a point-to-plane measurement technique. DQM calculates vertical and horizontal differences between swaths in a point cloud tile, which allows better analysis of the quality of a lidar project. Attendees will see a demonstration on how to use the tool and interpret the results with several real-world examples. The workshop will also show how to obtain the software, which is a government-furnished freeware for public use.
