Alan Rea Kenneth D. Skinner 2012 vector digital data http://water.usgs.gov/lookup/getspatial?ds680_originaldata Alan Rea Kenneth D. Skinner 2012 raster and vector digital data U.S. Geological Survey Data Series 680 Reston, VA U.S. Geological Survey These datasets each consist of a folder containing a personal geodatabase of the NHD, and shapefiles used in the HydroDEM process. These files are provided as a means to document exactly which lines were used to develop the HydroDEMs. Each folder contains a line shapefile named for the 8-digit HUC code, containing the NHD flowlines that comprise the coastline for that island. The “hydrolines.shp” shapefile contains the lines that were burned into the DEM. These lines were selected from the NHD flowlines, with some minor editing in places. The “wbpolys.shp” shapefile contains the water-body polygons that were selected from the NHD and used in the bathymetric gradient process. The folders for HUCs 20010000 (Hawaii) and 20020000 (Maui) also contain a “walls.shp” shapefile, which contains the lines that were superimposed on the surface as “walls.” These datasets were produced to support the StreamStats application for Hawaii. See USGS Data Series Report DS680 for complete information. 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) orig_data D:\data\hi_ss\orig_data\ (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
