Earth Systems Research Center (CSRC), under contract to the NH Office of State Planning (OSP), and in consultation with cooperating agencies, maintains a continuing program to identify and correct errors in these data. OSP, CSRC, and the cooperating agencies make no claim as to the validity or reliability or to any implied uses of these data. Polygon topology exists. Data are complete for the study area. Forest polygons from CCAP were selected and used in the eCognition software (version 10.1, Trimble, Inc.) as the basis to generate image objects to classify forested areas into several forest types. Reflectance values from Landsat 1, Landsat 2, and Landsat 3 were used as inputs to the eCognition multiresolution segmentation algorithm which generated the the image objects. The resulting image objects were subsequently classified using the Random Tree classification method (also from eCognotion). The classified forest polygons were then combined with the non-forest features from CCAP to produce the final landcover data set. This data included the original C_CAP, non-forest polygons and the reclassified forest polygons. 2024-02-01 Beginning landcover data from which forested classes were further classified.
