what I want to achieve is to have a section that you can add a photo from a device such as an iPhone, which will automatically fill in the field that is labeled something like 'location_description' with the location the photo was taken.
I can then use this field to display a google map showing the location.
So my question is can filemaker pro read the geotagged data from the photo? If yes please help.
I don't think there's a way to do this with just FileMaker Pro and FileMaker Go.
There might be a third party app that can extract the GeoTag so that you can add this to a field in your database. You'd have to search the web and see what's out there.
