Transect Video Replay Software

Since all the recorded video is georeferenced using the ship's onboard DGPS system, it is possible to view the video in spatial relationship to a chart of the study site. Using transect video replay software, a specific position on a particular transect can be selected, and the video footage corresponding to that location can be viewed. The position marker on the map will move synchronously with the video replay, thus showing the exact location of each video frame on the map.

Ocean Ecology uses several versions of transect video replay software, depending on the project and data viewing requirements.

Ocean Ecology has written its own in-house java-based software for viewing transect video data. This viewer is portable and can be used on a DVD or USB flash drive. It is standalone, and does not require an internet connection for data download.

Alternately, Ocean Ecology uses ActionCam, a GPS video viewer which can overlay GPS data on a variety of background maps provided by internet servers. Therefore, this system requires an internet connection. A portable version of MapServer is used to serve local project data to ActionCam.
