Summary

This portion of the data release presents digital surface models (DSMs) and hillshade images of the intertidal zone at Post Point, Bellingham Bay, WA. The DSMs were derived from structure-from-motion (SfM) processing of aerial imagery collected with an unmanned aerial system (UAS) on 2019-06-06. Unlike a digital elevation model (DEM), the DSMs represent the elevation of the highest object within the bounds of a cell. Vegetation, buildings and other objects have not been removed from the data. In addition, data artifacts resulting from noise in the original imagery have not been removed. The DSMs are presented with two resolutions: one DSM, covering the entire survey area, has a resolution of 4 centimeters per pixel; the other DSM which [...]

Purpose

These data were collected 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, a focus of the USGS Coastal Habitats in Puget Sound Project (CHIPS) and its partners to inform resource management and adaptive planning for our Nation's coasts. The DSM can be used with geographic information systems (GIS) software for research purposes.
