Several layers were uset to create this version (v 3.4). The original HabQual layer was developed by Jon Price and Jim Jacobi based on the mapped land cover units from the Hawaii GAP analysis program (Gon et al. 2006). This map was revised by combining data on land use and the \u201cBare\u201d category from the NOAA C-CAP 2005 map (NOAA National Ocean Service Coastal Services Center 2012), and adding road corridors to the heavily disturbed category based on the Tiger Roads layer (United States Census Bureau 2014). Additionally, corrections were made to this version of the map by visually inspecting previously mapped units and comparing them to recent high-resolution imagery including WorldView 2 multi-spectral imagery and to very-high resolution RGB imagery obtained from Pictometry Online (Pictometery International 2014). Changes were made to the map using the program GRID Editor developed by ARIS B.V. (2014) by Jim Jacobi. Latest edits made in September 2014.The starting raster \"Habqual\" was developed by Jim Jacobi, USGS PIERC. The bare earth category came from NOAA's CCAP dataset and was used to overwrite the original Habqual dataset for categories 2 & 3 (native and mixed). If Habqual was already distrubed (category = 1), then it was NEVER overwritten as bare earth; instead it remained classified as disturbed. Lastly, the TIGER roads layer was buffered and converted into a raster of category 1 (disturbed). The roads raster was then mosaic'ed on top of Habqual to expand the distrubed class to include roads & adjacent disturbed areas.This layer has four mapped values: 1 = heavily disturbed areas including agriculture and urban developments; 2 = mixed native-alien dominated plant communities; 3 = native dominated vegetation; and 4 = bare lands or <5% plant cover.ReferencesARIS B.V. 2014, GRID Editor for ArcMap.

The CAH General Map units were used to calculate current carbon stocks and the CAH Biome units were used as a starting point for projecting future distribution of the major plant communities from which potential future carbon stocks were calculated. While there have been many maps produced that depict vegetation for the state of Hawai\u2018i only a few of these display land cover for all of the main Hawaiian Islands, and most of those that were created before the year 2000 have very generalized units or are somewhat inaccurate as a result of more recent land use changes or due to poor resolution (both spatial and spectral) in the imagery that was used to produce the map. Some of the more detailed and accurate maps include the Hawai\u2018i GAP Analysis (HI-GAP) Land Cover map (Gon et al. 2006), the NOAA C-CAP Land Cover map (NOAA National Ocean Service Coastal Services Center 2012), and the more recently released Hawai\u2018i LANDFIRE EVT Land Cover map (U.S. Geological Survey 2009). However, all of these maps as originally produced were not considered to be detailed enough, current enough, or had other classification issues that would not allow them to be used as the primary base for the Hawai\u2018i Carbon Assessment.\nFor the Hawai\u2018i Carbon Assessment we integrated components from several of these previously mentioned land cover and land use mapping efforts and combined them into a single new land cover map (CAH Land Cover) that was further updated using very-high-resolution imagery. The hierarchical classification system of the CAH Land Cover map allows for grouping the mapped units into different configurations, ranging from very detailed plant communities reflecting current conditions to very generalized major land cover units and biomes that represent land use and potential vegetation zones, respectively. \nThe CAH Land Cover classification is hierarchical with forty-eight CAH Detailed Land Cover units which can be grouped into twenty-seven CAH General Land Cover units, thirteen CAH Biome units, and seven CAH Major Land Cover units (Appendix 1). The CAH Detailed Land Cover units generally correspond to the rUSNVC Association level, the CAH General Land Cover units are related to the rUSNVC Group level, and the CAH Biome units connect to the rUSNVC Subclass level.
