Summary

Imagery acquired with unmanned aerial systems (UAS) and coupled with structure-from-motion (SfM) photogrammetry can produce high-resolution topographic and visual reflectance datasets that rival or exceed lidar and orthoimagery. These new techniques are particularly useful for data collection of coastal systems, which requires high temporal and spatial resolution datasets. The U.S. Geological Survey worked in collaboration with members of the Marine Biological Laboratory and Woods Hole Analytics at Black Beach, in Falmouth, Massachusetts to explore scientific research demands on UAS technology for topographic and habitat mapping applications. This project explored the application of consumer-grade UAS platforms as a cost-effective [...]

Purpose

The orthomosaic image provides the optical surface reflectance of the land surface at a mid-day low-tide on 18 March, 2016. It was one of three products created to demonstrate the use of structure-from-motion for coastal research and to provide a means to test land cover classification from high-resolution imagery. An orthomosaic is distinct from an orthophoto mosaic in that it corrects for camera lens distortion and preserves distances. Thus, an orthomosaic simulates a photo in which every pixel in the scene was captured at nadir.
