Lapstrake Motorboat, Emerald Bay

This lapstrake motorboat (CA EB MF5) is lying under 42 feet of water on the sloped bottom of Lake Tahoe in Emerald Bay State Park. This vessel is part of the Emerald Bay Minifleet, which dates from between the late 19th century until the 1950s and is associated with the Emerald Bay Resort. The model documents an area of 16.7 square meters and is composed of 363 aligned images collected during a single 33 minute dive on 26 July 2016. Estimated error is 0.000979 m. This model was created out of a collaborative project between the Indiana University Center for Underwater Science and California State Parks. Images, photogrammetry, and virtual tour by M. Maus, Indiana University. Source: Objaverse 1.0 / Sketchfab

该搭接式摩托艇（lapstrake motorboat，CA EB MF5）沉没于塔霍湖翡翠湾州立公园的斜坡湖底，所处水深达42英尺。该艇隶属于翡翠湾微型船队（Emerald Bay Minifleet），该船队的建造年代介于19世纪末至20世纪50年代之间，与翡翠湾度假村（Emerald Bay Resort）存在关联。本数据集模型覆盖区域面积为16.7平方米，由2016年7月26日单次33分钟水下勘测作业中采集的363张配准图像构成。本次建模的估算误差为0.000979米。本模型源自印第安纳大学水下科学中心与加州州立公园管理局的合作项目。图像采集、摄影测量学（photogrammetry）与虚拟漫游制作均由印第安纳大学的M. Maus完成。来源：Objaverse 1.0 / Sketchfab
