  1. Values are calculated from platform angles, sensor angles, sensor position, frame center position, and slant range that are supplied by SLASetMetadataValues_t and SLASetMetadataFrameValues_t.
  2. Values are calculated from values supplied by SLASetMetadataValues_t and SLASetMetadataFrameValues_t, and by internal tracking position and box size. Target elevation is assumed to be the same as frame center elevation, and target latitude and longitude are calculated in a manner similar to the four corners. Track gate width and height are in pixels, derived directly from target box size.
  3. Values are calculated from internal tracking information. Multiple targets (either user-designated or automatically-generated) are indicated. Pixel coordinates are in `display' coordinates suitable for directly rendering over streamed digital video.

4-11enablesSet rate bit mask. Update the rate for the corresponding data element when bit value = 1
12frameStepFrame step at which to send the specified data values; 0 = disable sending KLV metadata, 1 = send each frame, etc. Per MISB STD 0601, version identifier fields for the UAS Local Data Set, Security Metadata Local Set, and Motion Imagery Track Metadata Local Set are emitted with elements of each local set. See also MISB ST 0902 for guidelines on setting the frame step for different fields.
