The model
Lock 21 at Dickinson 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 (up to 16,384 px).
