2010 Land Cover Project Final Report


The Lower Columbia River Estuary Partnership recently completed a high resolution land cover classification map for the Lower Columbia River and Estuary. The classification was done by the Sanborn Map Company, and incorporated recent (2009) aerial imagery, LiDAR, LandSAT and other supporting data sets. Additional support for this project was provided by the NOAA Coastal Services Center Coastal Change Analysis Program (C-CAP). Image classification utilized an innovative high resolution, image segmentation and object based approach that has been refined by Sanborn. The chosen classification scheme was based on existing, standard classifications, with additional focus placed on identifying estuarine and tidal freshwater habitats.
