Aerial Signal Cables are multi-conductor 600 or 2000-volt signal cables designed for aerial installation. They consist of ethylene propylene rubber insulated conductors, a moisture-resistant binder tape and a tough neoprene outer jacket. They are used in railroad signal circuits where continuity of service and long life are required in all vital circuit & safety related applications. They are designed for aerial applications and all wet or dry locations.
Aerial Triangulation is the process of collecting intersecting points of the same feature on different images and placing points of known coordinates in order to establish the position & orientation of the images at the moment of the camera exposure. Aerial Triangulation is a complex mathematical process that allows the formation of a photogrammetric block of stereomodels. This process allows the detection of faulty control points prior to data collection. The purpose of triangulation is to supplement the ground surveyed points with additional control points that are used to strengthen the solution.
