A new App, that I would like to see.....

[mikg02]

My official job title is "Scout" and I do a lot of scouting and exploring. I am a heavy GPS and digital camera user. I spend a lot of time sorting and organizing the photos. I often forget to note the photo number for a particular location. I would love to be able to take a picture and have the GPS coordinates recorded either in the photo data base or displayed in the photo. I do not yet have a 3G, and probably will not for a while, so can someone tell me.....can you choose which positioning system coordinates and displays to use, or are you stuck with WGS84 in Lat/Long? I think "Scout" would be a good name for the app.

The OS 2.0, not the 3G in particular, geotags your pictures when you take them (if you tap okay to let it use your position). The SDK provides the lat/long in degrees such as 40.7506, -111.4590. I don't know if the camera app translates that to anything else before storing it in the photo, but I would doubt it.

OK, we are making real progress here. It appears that we have some very strong tools to work with...1) an actual GPS receiver that already has dialogue with the operating system, 2) A camera that already allows stamping date and location coordinates in some system, 3) real interest in an application that could make work and leisure time a lot easier. I'll give you an example: I believe that Google Earth now allows for some kind of photo sharing of geographical points of interest. Hiking clubs or other wilderness adventurers could share trails with others, who could use the photos to decide where to plan their next excursion. For this type of activity you only need to ensure that the data coordinates are presented in WGS84 datum using the appropriate location format. Here is where a geodetic engineer with a hankering to write programs would be extremely helpful. A simple test would be to take one of your GPS photo's coordinates and plot them in Google Earth...then see where it is located, see if Google accepts the coordinates as given. If not, a Geodicist could come up with a routine to convert them to WGS84 and apply other magic that I am not competent to advise. Now, to make the app more helpful for people like me that do not normally work in WGS84 (the world standard) it must be able to transform the data into about 110 different datums and about 40 different location formats. But just getting it into WGS84 will be a major advance. Please remember that GPS is used world wide and iPhones are also being sold, or taken, world wide.

I'm not sure if it's WGS84, but you can take it and plot it in Google Maps (in fact, the location service is used by the Google Maps app) and also Google Earth.

Great news....I think I'm beginning to see a 3G in my near future.........

So how do you access that location information on the photos? I don't see any options in the camera roll on the iphone.

Sign me up for this class too!

I don't think you can on the iPhone. However, iPhoto got an update about two years ago to support geotagging. You can view it in there.
If you get the info of a photo, it is under Exposure.
