Alan Rea Kenneth D. Skinner 2012 raster and vector digital data Reston, VA U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?ds680_statewidelayers Alan Rea Kenneth D. Skinner 2012 raster and vector digital data U.S. Geological Survey Data Series 680 Reston, Virginia U.S. Geological Survey http://pubs.usgs.gov/ds/680/ This dataset consists of a workspace (folder) containing 41 gridded datasets and a personal geodatabase. The gridded datasets consist of 28 precipitation-frequency grids, a mean annual precipitation grid, eight land cover grids, two soil permeability grids, a synthetic stream grid, and a region grid used in the Hawaii StreamStats application for peak flow estimates. The personal geodatabase contains a polygon feature class of exclusion polygons, which identify areas in which use the StreamStats application is restricted. These datasets were produced to support the StreamStats application for Hawaii. The precipitation, land cover, and soil permeability grids are used to compute those characteristics for basins that have been edited by the user within the StreamStats web application. The same grids were used to compute continuous parameter grids. The continuous parameter grids are distributed with the ArcHydroHUC data sets for each 8-digit HUC, and are used in characteristic computations for unedited basins. The region grid is used to identify which regional regression equations to apply for estimating streamflow statistics in Hawaii. The exclusion polygons are used to restrict or prevent use of the StreamStats application in areas where results may be invalid, or where its use is to be prevented for various reasons. Each compressed download file (with a “.zip” extension) contains the version information in the filename in the form of “Vnn,” where “nn” is the data version number. In this manner, each data component may be versioned and distributed independently. The data is distributed in ”.zip” files, one per 8-digit HUC, plus one ”.zip” file for the ArcHydro Global dataset, one for the statewide layers, and one for the original data. For example, the file “DS680_20020000_V01.zip” would contain the entire folder for HUC 20020000 (Maui). A file named “DS680_20020000_V02.zip” would indicate that data have been updated, and that version 02 data should be used. If a change to one dataset results in the need to change others, all affected datasets will be updated, and the data distribution site will be maintained so it includes a complete set of compatible dataset versions. Each ”.zip” file includes a text file (like this one) that indicates the version of the accompanying data component. For example, the “DS680_20020000_V02.zip” file would contain a file named “DS680_20020000_V02.txt,” which will extract into the archydro\20020000 folder. The name of this file will indicate the version of the data in the folder. The file itself contains an explanation of the versioning system, and a summary of edits made since the first version of the dataset was released. To replace an old version with a newer version, the old version of the data component should be deleted, following the example below, before the new version is extracted into its place. Example instructions for updating data components from geospatial datasets: --------------------------------------------------------------------------- Component Delete prior to extracting new version of ".zip" file --------------------------------------------------------------------------- ArcHydroGlobal D:\data\hi_ss\archydro\global.mdb StatewideLayers D:\data\hi_ss\statewide\ (delete entire folder) Huc# D:\data\hi_ss\archydro\Huc# (delete entire folder) --------------------------------------------------------------------------- where HUC# is the 8-digit Hydrologic Unit Code and D:\data\hi_ss\ is the disk location where ZIP file archives were extracted. 2012 publication date Complete None planned -159.789288 -154.732099 22.233206 18.893342 None inlandWaters streamflow statistics streamstats forest land cover slope elevation aspect precipitation GCMD Location Keywords NORTH AMERICA UNITED STATES UNITED STATES OF AMERICA Hawaii None None U.S. Geological Survey Alan Rea mailing address
