    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Aquifer protection study, town of Sharon : subsurface data points / IEP Inc. It was published by IEP Inc. in 1987. Scale [ca. 1:25,000]. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Massachusetts State Plane Coordinate System, Mainland Zone (in Feet) (Fipszone 2001). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, railroads, drainage, cities and other human settlements, territorial boundaries, shoreline features, and more. Includes also watershed labels, subsurface data points and legend, and topographic distinctions. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features.
