EXIF GPS extraction

[saltydog73]

I need to write a simple program that will extract GPS data from a tagged photo and place it in a csv file. I am having issues getting the GPS data from the jpeg's EXIF. I can get all the simple photo attribute data but I cannot seem to locate the GPS data. If I use image.getpropertyitem, I am returned with ID, Len, Type, and Value; Value gives me an array of integers. Can anyone help me with the location of the GPS data in EXIF and how to extract it? My IDE is VS 2008 Pro and I am trying to write this in VB .NET. Thanks
