Hi Pamela, We are using the geocoding service to convert addresses, download the tiles for a DL sized spacial region, centering on the returned placemark, finally saving a copy of the image for use in a marketing campaign.
We have a premier account and have been granted permission to do this. Please contact me privately if you need further details. Do you think that if we used flash player in the browser instead of AIR, we could get around this issue? If not would we be better off using the AJAX API? regards Ben On Aug 31, 11:43 am, "pamela (Google Employee)" <[email protected]> wrote: > Hi Ben- > > There are various reports of memory issues with AIR, but I'm a bit > concerned about your application's purpose.
