| Description |
The U.S. Geological Survey (USGS) Remote Sensing Coastal Change (RSCC) project collects aerial imagery along coastal swaths with optimized endlap/sidelap and precise position information to create high-resolution orthomosaics, three-dimensional (3D) point clouds, and digital elevation/surface models (DEMs/DSMs) using Structure-from-Motion (SfM) photogrammetry methods. These products are valuable for measuring topographic and landscape change, and for understanding coastal vulnerability and response to disturbance events. This is an ongoing collection of nadir (vertical) aerial imagery surveys of coastal environments. Low-altitude digital aerial imagery is acquired with a manned, fixed-wing aircraft using the "Precision Airborne Camera (PAC)" system. The system is operated by C.W. Wright and consists of a mounted digital camera fitted with a prime lens, along with a custom integrated survey-grade Global Navigation Satellite System (GNSS) receiver. [More]
