Zoner Photo Studio lets you work with longitude, latitude, and altitude. You can assign coordinates to pictures here, and display their coordinates on a map as well. You can have the program batch-assign coordinates from a GPS device's tracklog, or assign them by hand using an online map.
The coordinates are recorded to both EXIF and XMP picture information, so that you can process them and work with them in many other programs, not just Zoner Photo Studio. Some of the Web galleries you can make in the program can also show pictures' GPS coordinates on a map.
