Digital watermarking technology is used to convey location data for images or objects depicted in video. A digital watermark may associate geovector information with the video or object and areas depicted in the video. A geovector may include location coordinates such as longitude, latitude, altitude, etc. In one implementation, geovector information is embedded within a video frame so as to correspond with an area depicted in the video frame's center or off-center location. In a second implementation, a geovector includes an identifier or indexing protocol for use in a video management system.
