Gmap/location design question
I don't know the relative merits of Node locations vs Location CCK for this scenario, but the CCK option's worked for me. Edit: With GMap enabled, you can select a Google Map as the field's formatter by going to Content management -> Content types -> Edit [content type] -> Display fields. If GMap's enabled, you should see an option Map only. CCK will handle storing the data. See my comment on this Q for how to get the table details. Edit2: Actually, if memory serves, Location doesn't store the CCK data as you might first expect. location.module stores locations in its own table, and the CCK field just stores an ID into that table.
