the GIS Data Depot

Sites listed here are key lists of geo-data sources sponsored and compiled by others.
The original sites referenced here were the topic of an article I wrote in 1997.
It appears that the FGDC is no longer maintaining (or making available) their lists of other geodata sites which the article referenced, and do not appear here.
