GCIP Reference Data Set (GREDS) CD-ROM, U.S. Geological Survey Open-File Report 94-388
The data sets on this compact disc are a compilation of several geographic reference data sets of interest to the global-change research community. The data sets were chosen with input from the Global Energy and Water Cycle Experiment (GEWEX) Continental-Scale International Project (GCIP) Data Committee and the GCIP Hydrometeorology and Atmospheric Subpanels. The data sets include: locations and periods of record for stream gages, reservoir gages, and meteorological stations; a 500-meter-resolution digital elevation model; grid-node locations for the Eta numerical weather-prediction model; and digital map data sets of geology, land use, streams, large reservoirs, average annual runoff, average annual precipitation, average annual temperature, average annual heating and cooling degree days, hydrologic units, and state and county boundaries. Also included are digital index maps for LANDSAT scenes, and for the U.S. Geological Survey 1:250,000, 1:100,000, and 1:24,000-scale map series. Most of the data sets cover the conterminous United States; the digital elevation model also includes part of southern Canada. The stream and reservoir gage and meteorological station files cover all states having area within the Mississippi River Basin plus that part of the Mississippi River Basin lying within Canada. Several data-base retrievals were processed by state, therefore many sites outside the Mississippi River Basin are included.
This is a compilation of geospatial data sets formatted for use in geographic information systems (GIS). The data sets, sources scales, and projection were chosen to support the global change research community; specifically the Global Energy and Water Cycle Experiment (GEWEX) Continental-Scale International Project (GCIP).
This metadata is for a compilation of data sets published on CD-ROM. The README file contains complete information on the contents of the CD-ROM. Metadata are available for the individual data sets.
DISC ORGANIZATION
This disc complies with the ISO 9660 standard for CD-ROM discs. It is
intended for use with personal computers using the MS-DOS operating
system. The disc is compatible with UNIX, Macintosh, and VAX
computers equipped with the appropriate CD-ROM reader and software.
All ASCII files, including Digital Line Graph (DLG) files and ARC/INFO
export files, use MS-DOS record delimiters (carriage-return,
line-feed). Conversion of record delimiters in these files may be
necessary for operating systems other than MS-DOS. The overall layout
of the disc is:

Users are warned that several of the data sets are very large, and downloading times are likely to be significant.
Several users have reported problems importing the ARC/INFO export files on UNIX workstations. The files have MS-DOS record delimiters (carriage-return line-feed) rather than UNIX newline delimiters. The "dos2unix" utility found on many UNIX platforms can be used to replace the record delimiters for use with Workstation ARC/INFO. If "dos2unix" is not available, the following Perl program will accomplish the same task:
#! /usr/bin/perl -pi.dosbak
s/\r\n$/\n/
The "uscandem" DEM data set in the "xportarc" subdirectory is stored in ARC/INFO Grid format. To retrieve this data set, the entire "uscandem" and "info" subdirectories (under "xportarc",) should be downloaded with all files named identically and stored in the same directory paths relative to each other.
