The location depends on the precision you need. I did this with lat/long to six decimal places because the client needed rooftop-level precision. If using town names is an acceptable level of precision, you will still need to do a lookup first in order to determine the lat/long coordinates for actual icon placement. My information stems from experience with Google Maps API v2 and v3 so YMMV. -Jay On Thu, Oct 25, 2012 at 11:15 AM, Bob Meetin <bobm at dottedi.biz> wrote: > Maps: > > I have a project in hand that involves displaying a google map or similar > and positioning entities onto the map.
