These raster-based land cover products are developed through entirely automated methods. Initial mapping was conducted at 1-meter resolution using aerial imagery, lidar elevation, and ancillary information. The result was a six-category land cover that was resampled to 10 meters and combined with wetland information from the National Wetland Inventory (NWI) to produce this BETA-level product, with up to 15 categories of land cover. Three file types are available: a 10-meter resolution land cover, a 30-meter percent man-made impervious layer, and a 30-meter percent canopy layer.
While produced as part of the Coastal Change Analysis Program (C-CAP), these products should not be compared directly to past dates of 30-meter C-CAP to identify change, as there will be vast differences caused by the different methods and the classes mapped.
Please provide feedback on the quality of these beta products. Tell us what you think about the usefulness (or shortcomings) of these products, especially compared to our Regional or High-Resolution C-CAP land cover data.
