We’ve all heard and repeated the quote that 80% of all data contains some reference to geography. It’s one of those easy to remember, and quite believable statistics that has been passed down since the early 1990s. I’ve often wondered where that quote came from, have asked several people in the past, and get asked the question myself. I received a reference for the quote from Beniamino Murgante, lecturer of Spatial Analysis and Planning at the Universit of Basilicata and editor of Geocomputation and Urban Planning, a volume from Springer Verlag.
The reference is: Franklin, Carl and Paula Hane, “An introduction to GIS: linking maps to databases,” Database. 15 (2) April, 1992, 17-22.
The periodical Database was published from 1978 through 1999 as, “the magazine of database reference and review.” I haven’t had a chance to get to a library yet to view the full article, but here’s the abstract:
Discusses the impact of computerization of maps on access to business and government information that may be geographically referenced and the emergence of a new field, Geographic Information Management (GIM). Applications of hypertext/hypermedia in Geographic Information Systems (GIS) are described, and software available for workstations and microcomputers are reviewed.
If anyone has a copy of the magazine or access to the online archive via your education account, I’d love to see the full quote in context.
