We developed a completely new free geospatial dataset and substituted all Spearfish (SD) examples in the previous editions with this new, much richer North Carolina (NC, USA) data set. This data set is a comprehensive collection of raster, vector and imagery data covering parts of North Carolina (NC), USA, prepared from public data sources provided by the North Carolina state and local government agencies and Global Land Cover Facility (GLCF).
