2008 Land Cover Data Set
Last Updated 10/14/2010
H-GAC unveils the 2008 land cover data set which maps the 15 counties that encompass the Clean Rivers Program’s (CRP) assessment basins. The 2008 land cover data set updates the 2002 land cover map and is available in three formats: an original 10 category classification and two reprocessed classifications which slightly modify the original map. The 10 category classification used in this land cover delineation follows the hierarchical classification scheme utilized by the National Land Cover Data (NLCD). Due to accuracy limitations the land cover data is not to be used for regulatory, jurisdictional or local planning decision making without thorough field verification.
