Managers, engineers and researchers require up-to-date snow information such as coverage, depth and water content. These elements can be quite difficult to accurately measure. A stepwise approach is recommend, focusing on snow surface, and monitoring of snow melt. For the last few years, Unmanned Aerial Vehicles (UAV-drone) can be used for multi-temporal aerial surveys of snow cover. To generate accurate geographically located UAV-derived products, a high precision GPS survey of the field site is required prior to UAV data collection. Precise geographically known reference points (ground control points) are marked in the field and located in the UAV imagery during geo-correction processing. A case study was completed in a test site located in the Acadia forest near Fredericton, NB. This document describes in detail the method and results of the GPS survey used for the geographic rectification of numerous photographs acquired by the UAV within the scope of this project”--Summary provided by publisher. |
