MassGeotagger lets you select a photo, a photo folder or a folder tree and update the latitude and longitude coordinates in the EXIF data of the selected photos. To get the GPS coordinates, the method of choice is to select one or several GPX files and set the difference of time between APN time saved in EXIF data and GPS time. However other strategies to match JPG and GPS coordinates are available : by selecting one of the GPX waypoint, by selecting a point on the map or by user input.
