Tactical Technology Collective has put together a great book Maps for Advocacy: An Introduction to Geographical Mapping Techniques (http://www.tacticaltech.org/mapsforadvocacy). Use of maps in the political and activism space is growing and very successful. —GregElin, Sunlight Foundation.Summary blurb from the Tactical Technology Collective website:
"The booklet is an effective guide to using maps in advocacy. The mapping process for advocacy is explained vividly through case studies, descriptions of procedures and methods, a review of data sources as well as a glossary of mapping terminology. Scattered through the booklet are links to websites which afford a glance at a few prolific mapping efforts. "
Indeed, in 44 pages the booklet provides coverage of the majority of the web based mapping technologies available today that don't require purchasing a license. One of the best parts of the book is the roadmap to the technologies based upon what a user wants to do.
