Get GPS data from an image Java code

There's no easy way to do it with the Java Core API. You'd have to parse the image's metadata tree, and interpret the proper EXIF tags. Instead, you can pick up the required code from an existing library with EXIF-parsing capabilities, and use it in yours. For example, I have used the Image class of javaxt, which provides a very useful method to extract GPS metadata from an image. It is as simple as:

javaxt.io.Image image = new javaxt.io.Image("D:\\codeTest\\arun.jpg");
double[] gps = image.getGPSCoordinate();

Plus, javaxt.io.Image has no external dependencies, so you can just use that particular class if you don't want to add a dependency on the entire library.

I suggest you read the EXIF header of the image and then parse the tags for finding the GPS information. In Java there is a great library (called metadata-extractor) for extracting and parsing the EXIF header. Please see the getting started for this library here.

Once you do the first 2 steps in the tutorial, look for the tags starting with [GPS] ([GPS] GPS Longitude, [GPS] GPS Latitude, ...).
