Land cover is defined using the EnviroAtlas merged version of the Coastal Change Analysis Program's (C-CAP) 2005 - 2010 layer for Hawaii. Steams were derived from the NHDPlus Version 2 dataset. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets). This dataset is useful for evaluating the potential value of ecosystem services provided by vegetation communities, and the impacts of developed land cover. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation. completed EnviroAtlas Coordinator U.S. Environmental Protection Agency, Office of Research and Development - Center for Public Health and Environmental Assessment (CPHEA), EnviroAtlas Geospatial Data Owner (919) 541-3832 109 T.W.

The land cover input is the EnviroAtlas merged version of the Coastal Change Analysis Program's (C-CAP) 2005 - 2010 layers for Hawaii (https://coast.noaa.gov/digitalcoast/tools/lca). The stream inputs were derived from the NHDFlowline, NHDWaterbody, and NHDArea shapefiles in the NHDPlus Version 2 datasets (http://www.horizon-systems.com/NHDPlus/NHDPlusV2_home.php). For more information on the metric calculation, please see the ATtILA User's Manual included with the toolbox. A comprehensive list of metric creation steps is included in the Processing Steps.

The strmLine tool selects line segments from the NHDPlus NHDFlowline layer that are defined as FTYPE = Stream/River or Connector or Artificial Path. 2017-08-28T00:00:00 Processed NHDArea and NHDWaterbody layers in the NHD with the strmAreal Tool in the AtlasAnalyses Toolbox (a self-created toolbox for the purpose of standardizing analyses for the EnviroAtlas). The strmAreal tool extracts Reservoir, LakePond, and Ice Mass waterbodies that intersect the previously processed NHD flowlines and merges them with any NHDArea wash, rapids, streamriver, or lock chambers that also intersect the processed NHDFlowlines. 2017-08-28T00:00:00 Calculations were done using the Riparian Land Cover Proportions tool in the Riparian Characteristics toolset of the ATtILA for ArcGIS toolbox (ATtILA 10_0.tbx, 5/26/2016 version) in ArcGIS. Calculated rNI45, rfor45, and rfor9045. Used NHDPlusV2_WBDSnapshot_EnviroAtlas_HI as the reporting unit feature, HI_CCAP_Land_Cover_2005_2010_EnviroAtlasVersion as the land cover grid, and strmLineHI20 and strmArealHI20 as the stream features. Used a user-defined land cover scheme for the C-CAP dataset named, EnviroAtlas C-CAP LAND.xml. 2016-08-30T00:00:00 Renamed fields rNI45, rfor45, and rfor9045 to RNAT45, RFOR45, and RFOR9045, respectively. 2017-09-20T00:00:00 unknown 2029-07-23 This metadata was automatically generated from the FGDC Content Standard for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2024-02-09T11:11:00 version of the FGDC CSDGM to ISO 19139 transform.
