The current S60 3rd FP1 onward phones (Nokia N-series) do have that feature built in. So whenever you shoot a picture and have a position, this position is entered into the image and recognized by public services, like panoramio. If you upload the image to panoramio, it will appear a couple of weeks(!!) later on a Google map, using the panoramio overlay.
But of course, you are free to provide a map by yourself and position the image yourself. You have to take the photo, gain the GPS position or the MNC/MCC/CID/LAC from the phone (the cell info), or any other info of networks around (e.g. WiFi), resolve this to a Lat/Lon using public services (like sykhookwireless or Google Gears or whatever), patch the position into the JPG and send it up, either by MMS or by web access. At least for Symbian S60 Python for S60 gives you all the power to do this with a snip. Pretty easy. If you need more info, please contact me directly. There are some issues with legal aspects and the accuracy, which have to take into account. Regards At least for Symbian S60 (e.git would be rather simple to do this. You would have to ad the positioning information as EXIF tag to the JPG image. > If so, does anyone have any idea of the locational accuracy we might > get or potential legal problems we might run in to? > > Any help would be much appreciated! > > Nick > > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
