Emerald Bay Barge 3D Model
This is one of two barges now lying adjacent together near the southern shore of Emerald Bay State Park, Lake Tahoe. Historically, the barges were lashed to the sides of a lake steamer, and used to transport construction materials and other bulky commodities. Both barges likely sank at their moorings some time after construction of the Lake Tahoe highway in 1913.
The model documents an area of 507 square meters and is composed of 2636 aligned images collected from an average distance to target of 1.93 m during a single dive on 27 July 2016. Estimated scalar error is 0.003472 m. According to photogrammetric measurements, the vessel dimensions are 9.5 m x 59.3 m.
This model was created out of a collaborative project between the Indiana University Center for Underwater Science and California State Parks. Images collected by Matthew Maus and Sam Haskell, Indiana University, during the Lake Tahoe Underwater Photogrammetry Workshop in July 2016.
