Figure 4 shows the elevation profile over the deck of the SdC Bridge from the tri-stereo DSM, with the positions of the main features called out. The expected slope asymmetry on either side of the Seaway navigation channel is observed in the DSM, and the main span tower is a prominent pinnacle above the highest part of the bridge deck.
