[OSGeo-Discuss] offline maps

[Peter Batty]

The terms of service prohibit offline caching of Google Maps tiles. This is
one major advantage of OpenStreetMap, which does permit you to do this.

The terms are at http://code.google.com/apis/maps/terms.html

Relevant items are:

You must not ...


   10.3 pre-fetch, cache, or store any Content, except that you may store
   limited amounts of Content for the purpose of improving the performance of
   your Maps API Implementation if you do so temporarily, securely, and in a
   manner that does not permit use of the Content outside of the Service;

   10.6 use the Service in a manner that gives you or any other person
   access to mass downloads or bulk feeds of any Content, including but not
   limited to numerical latitude or longitude coordinates, imagery, and visible
   map data;
