Short Description of your Research or Creative Project (700 characters or less)

In this project, GSP 330 (Mobile Mapping) students evaluated 3 methods of collecting three dimensional (3D) data at Ma-le'l Dunes Park in Arcata, CA. Data was collecting using 1) Autolevels, 2) Total Stations, and 3) Unmanned Aerial Vehicle (UAV). The XYZ data collected by the first two methods were converted to GIS data and then modeled into a Digital Elevation Model (DEM). Aerial images from the UAV were processed with Photoscan's Structure from Motion (SfM) algorithm to generate a point cloud and DEM. The point clouds from all methods were then processed into cut-fill rasters and Triangulated Irregular Networks (TINs) for visualization and comparison.
