Understanding current conditions and past change is essential to improving natural resource management in the future. Through its Coastal Change Analysis Program (C-CAP), NOAA’s Office for Coastal Management produces standardized land cover and change information for the coastal U.S. Current products include both regionally focused, moderate resolution (30 m) data that is updated every 5 years and high resolution (1-4 m) maps that provide more detail in areas experiencing high rates of land cover change, bringing this national framework to the local level. In the past, high resolution data acquisition has been expensive and deriving data products can be labor intensive, but recent increases in imagery and LiDAR data availability combined with improvements in processing techniques are enabling more cost-effective production of high resolution land cover products. This presentation will describe techniques NOAA and its partners are using, as part of the 2016 update cycle, to develop such detailed land cover information across broadening geographies and how these efforts can be leveraged to better meet management needs at a lower cost.
