You are reading this page because you are thinking about learning
to do your own Business Geographics...
...so here is a 30-second
overview on a fairly complicated topic.
First, you need to have a general understanding of statistics
and/or business finances. Also you need some understanding of
mapping (cartographic) principles. If you are a novice to
mapping, the single best book I recommend you read is How to Lie
with Maps by Mark Monmonier (University of Chicago Press, 1991
ISBN 0-226-53415-4) In particular the 20 pages of Chapter 9
cover the basic issues of data maps better than some tomes.
This has been a rapidly growing area, and I need to update this page
with current information to make it useful.
