Structure From Motion Elevation Model For Adding Topographic Correction To Ground Penetrating Radar, Leslie A. Mowbray
Student Research Symposium
High resolution elevation models have become a standard tool in environmental, geological and archaeological investigations, however; the cost of acquiring Lidar in remote areas, on small project sites or over repeated time intervals remains prohibitively expensive. Here, open-source software and GIS are used to create a digital elevation model (DEM) from aerial photos in a process known as Structure from Motion (SfM). This process is a fraction of the cost of Lidar acquisition, and is shown to produce a model with comparable resolution. The photos used here were taken from a camera hung from a balloon flown at Mickey Springs …
