The 2010 LCRE classified land cover data set, with an emphasis on estuarine and tidal freshwater vegetation types, was derived using a high resolution image segmentation and object based classification process. The primary data sources include the following: a) 2009 4 band, 1 meter resolution airborne imagery acquired by the USDA National Agriculture Inventory Program (NAIP); b) archived 30m LandSAT TM5 imagery from various dates ranging from 2007-2009; c) 2009-2010 LiDAR elevation data aquired by the US Army Corps of Engineers. The minimum mapping unit, defined as the smallest specified area for mapping an individual landform, is 0.25 acres.
