This dataset represents the cumulative result of multi-season classification of land cover in the GCPO LCC geography to NatureServe Ecological Systems based on 2011 seasonal Landsat Satellite Imagery. The approach used a Random Forest algorithm and several dozen input data layers to classify land cover at a 30 m pixel resolution. The description below is taken directly from the report titled “Update of the Eastern GCPO Land Cover Database to 2011 Using a LS2SRC Approach”, by Dr. Qingmin Meng, Department of Geosciences, Mississippi State University.Random Forest classifier is based on the general decision tree approach, which has been a popular approach to multilevel and multistage decision making. Its basic idea...

This dataset compiles land ownership and management data from state and federal agencies to create a map showing ownership, management, and conservation status of all land in Alaska. State, federal, and private lands, including Native corporations and Native allotments, are included. Conservation status describes the degree to which land, particularly public land, is legally designated and explicitly managed for biodiversity conservation. The most common classification, developed by the USGS GAP Program (www.gap.uidaho.edu), classifies land management types into four conservation status categories according to the degree to which the land is explicitly managed for conservation. In general, conservation status 1...

The Protected Areas Database of the United States (PAD-US) is a GIS database hosted by the USGS Gap Analysis Program (GAP) that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. Version 1.2 of this data set was released by GAP in April, 2011 and can be downloaded from the USGS PAD-US web site (data available in geodatabase and shape file formats). The web site includes an online map viewer for the data as well as information on PAD-US standards, core attribute schema and a summary of commonly requested statistics. GAP compiled the Protected Areas Database of the United States (PAD-US) version 1.1 with significant...

GAP species range data show a coarse representation of the total areal extent of a species or the geographic limits within which a species can be found (Morrison and Hall 2002). To represent these geographic limits, GAP compiled existing GAP data, where available, and NatureServe data (Patterson et al. 2003, Ridgely et al. 2007, NatureServe 2010) IUCN data (IUCN 2004), where needed. Data provided by GAP in collaboration with the Northwest Gap Analysis Project (NWGAP), the Southwest Regional Gap Analysis Project (SWReGAP), the Southeast Gap Analysis Project (SEGAP), the Alaska Gap Analysis Project (AKGAP), the Hawaii Gap Analysis Project (HIGAP), the Puerto Rico Gap Analysis Project (PRGAP), and the U.S. Virgin Islands...

This layer represents State Habitat and Species Mangement Areas in Wyoming from the Protected Areas Database of the US (PADUS). Part of the GAP Analysis, PADUS is a geodatabase that illustrates and describes public land ownership, managment and consercationlands nationally. The lands included are assigned conservation measures that qualify thier intent to mangae lands for the presercation of biological diversity and to other natural, recreational, and cultural uses.
