Answer 1

The MetadataExtractor library has been available for Java since 2002 and is now fully supported for .NET. It supports Exif GPS data from JPEG files, along with a tonne of other metadata types and file types.

Here are examples of the output from an iPhone 4, iPhone 5 and an iPhone 6.

It's available via NuGet:

PM> Install-Package MetadataExtractor

Then, to access the GPS location, use the following code:

var directories = ImageMetadataReader.ReadMetadata(jpegFilePath);

var gps = directories.OfType().FirstOrDefault();

var location = gps?.GetGeoLocation();

if (location != null)
    Console.WriteLine("Lat {0} Lng {1}", location.Latitude, location.Longitude);

Or to print out every single discovered value:

var lines = from directory in directories
            from tag in directory.Tags
            select $"{directory.Name}: {tag.TagName} = {tag.Description}";

foreach (var line in lines)
    Console.WriteLine(line);
