Since 2000, the Estuary has produced a number of land cover classifications and related products for the region, using various technologies.
2009 Lower Columbia River High Resolution Land Cover Data
This 1-meter resolution land cover classification data is our latest regional land cover product and was funded by the Bonneville Power Administration in 2010, as part of the Columbia River Estuary Ecosystem Classification. The data set was created by Sanborn, in collaboration with the NOAA Coastal Change Analysis Program (C-CAP). The classification scheme is based on existing standard classifications, with additional detail provided for estuarine and tidal freshwater habitats.
