THE GLOBAL LAND INFORMATION SYSTEM Public Geographic Database

The Global Land Information System (GLIS) is an interactive computer system developed by the U.S. Geological Survey (USGS). GLIS contains descriptive information about data sets (keyword searchable); user guides with detailed information about sensor specifications, extent of coverage, processing history, data quality, and product availability; and inventories which contain detailed information about individual data set entities such as a Landsat scene or an Advanced Very High Resolution Radiometer (AVHRR) pass (temporal, spatial, and parameter-oriented queries of inventories are possible). In addition to the text-based directories, user guides, and inventories, GLIS graphic services are available through graphic interfaces such as a PC-GLIS package for IBM- compatible PCs or the X Windows environment.

GLIS is available from Internet via TELNET glis.cr.usgs.gov or TELNET 152.61.192.54. Modem dial-in is available at 1+605+594-6888 or FTS (federal telephone system) 753-7888, which is undoubtedly long distance to practically everyone and is not PC-Pursuitable since the system is located in Sioux Falls, South Dakota. Email can be sent to glis@glis.cr.usgs.gov.

Some user assistance and information can be received from 1+800+252-4547 or FTS 753-7099 or commercial 1+605+594-6099.

No access to GLIS is available for those of us who have FTP/email/news only. None of the Freenets have any teleport connectability to GLIS. There is no listserv function (automated email response) available at GLIS. Unless you have Telnet (or a goodly long distance budget) you are among us who are out of luck with respect to GLIS information. All of this information is as of the last time I tried to contact GLIS in May 1993.
