This map shows coastal features such as lighthouses, buoys, beacons, rocks, channels, points, coves, islands, bottom soil types, wharves, and more. Includes also selected land features such as roads, railroads, drainage, land cover, selected buildings, towns, and more. Relief shown by hachures and spot heights; depths by sounding, shading, and contours. Includes inset map: Sub-sketch of entrance to San Francisco Bay (Scale 1:400,000), and inset views: View of the entrance to San Francisco Bay, Alcatraz N.E. by E. 1/2 (by compass 10 miles) -- View of the entrance to San Francisco Bay from Yerba Buena Id. -- View of the entrance to San Pablo Bay from near Angel Id. Also includes text and tables. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.

Boston Bay (1886), Massachusetts 15 Minute Digital Raster Graphic

This layer is a digital raster graphic of the historic 15-minute USGS topographic map of the Boston Bay, Massachusetts quadrangle. The survey dates (ground condition) dates for this map are 1886 and 1887. This map includes coverage of Cohasset, Hull, Quincy, Marblehead, Lynn, Swampscott and, in general, the coastal areas encompassing Boston Harbor and the larger area of the Bay. The Boston Harbor Islands are also depicted. A digital raster graphic (DRG) is a scanned image of a U.S. Geological Survey (USGS) standard series topographic map, including all map collar information. The image inside the map neatline is geo-referenced to the surface of the earth and fit to the Universal Transverse Mercator projection. The horizontal positional accuracy and datum of the DRG matches the accuracy and datum of the source map. The names of quadrangles which border this one appear on the map collar in their respective positions (N,S,E,W) in relation to this map.
