The model

Lock 21 at Dickinson's Landing, under the St. Lawrence since 1958, surveyed zone by zone with underwater photogrammetry. Every zone is assembled into a single model; the zones not yet digitised are added dive after dive. The ground around is modelled, not surveyed.

Detail loads as you get closer: from afar, a lighter version; up close, the zones' full texture.
