Summary

An unmanned aerial system (UAS) was used to acquire high-resolution imagery of the intertidal zone at West Whidbey Island, Washington on June 4, 2019. This imagery was processed using structure-from-motion (SfM) photogrammetric techniques to derive a high-resolution digital surface model (DSM), orthomosaic imagery, and topographic point clouds. In order to maximize the extent of the subaerially exposed area, the survey was timed to coincide with a spring low tide occurring at approximately 18:02 Universal Coordinated Time (UTC) (11:02 Pacific Daylight Time (PDT)), with a predicted water level of -0.74 meters below mean lower-low water (MLLW) at the Sunset Beach NOAA subordinate tide station (station ID 9447951). A total of eleven [...]

Purpose

These data sets are intended to be used to characterize the morphology, substrate composition and roughness of intertidal areas to support modeling of coastal storm and wave impacts with sea-level rise as part of the USGS Puget Sound Coastal Storm Modeling System (PS-CoSMoS). The data are also intended to be used to model and evaluate sediment transport and its effects on coastal habitats, which is a focus of the USGS Coastal Habitats in Puget Sound Project (CHIPS) and its partners to help inform resource management and adaptive planning for our Nation's coasts.
