Maine Coast, Gouldsboro Bay to Moose Cove, Nautical Chart, 1776 (Image 2 of 3) (Raster Image)

This layer is a georeferenced raster image of the untitled, historic nautical chart: [A chart of Mechios, Pleasant Bay, Naraguagus River, Pigeonhill Bay, Goldsborough &c.] (sheet originally published in 1776). The map is [sheet 45] from the Atlantic Neptune atlas Vol. 3 : Charts of the coast and harbors of New England, from surveys taken by Samuel Holland and published by J.F.W. Des Barres, 1781. Scale [ca. 1:50,000]. This layer is image 2 of 3 total images of the three sheet source map, representing the central portion of the map. Covers the coast of Maine from South Addison to Machias Bay. The image is georeferenced to the surface of the earth and fit to the 'World Mercator' (WGS 84) projected coordinate system. All map collar information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, or other information associated with the principal map. This map shows coastal features such as harbors, inlets, rocks, channels, points, coves, shoals, islands, and more. Includes also selected land features such as cities and towns, and buildings. Relief is shown by hachures; depths by soundings. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection. The entire Atlantic Neptune atlas Vol. 3 : Charts of the coast and harbors of New England has been scanned and georeferenced as part of this selection.

Chicago and vicinity, Illinois, 1953 (Image 2 of 3) (Raster Image)

This layer is a georeferenced raster image of the historic, topographic paper map entitled: Chicago and vicinity, Ill.-Ind. : sheet no. 2 of 3 (Chicago Loop), 1953, mapped, edited, and published by the Geological Survey. It was published in 1957. Scale 1:24,000. The source map was compiled from 1:24,000 scale maps of Chicago Loop, River Forest, Elmhurst, Hinsdale, Berwyn, Englewood, Jackson Park, Calumet Lake, Blue Island, Palos Park, and Sag Bridge, 1953 7.5 minute quadrangles. Hydrography from U.S. Lake Survey Charts 75 (1:120,000), 751 (1:60,000), 752 (1:15,000), and 755 (1:15,000). This layer is image 2 of 3 total images of the three sheet source map. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Illinois East State Plane Coordinate System NAD27 (in Feet) (Fipszone 1201). 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 is a typical topographic map portraying both natural and manmade features. It shows and names works of nature, such as mountains, valleys, lakes, rivers, vegetation, etc. It also identify the principal works of humans, such as roads, railroads, boundaries, transmission lines, major buildings, etc. Relief is shown with standard contour intervals of 5 feet. Depths shown by isolines and soundings. 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, Massachusetts Region 1:5,000 Color Ortho Imagery (1/2-meter Resolution), 2001

1/2-meter resolution 1:5,000 orthophoto image of the Boston region from April 2001. This datalayer is a subset (covering only the Boston region) of the Massachusetts statewide orthophoto image series available from MassGIS. It consists of 23 orthophoto quads mosaicked together (MassGIS orthophoto quad ID: 229890, 229894, 229898, 229902, 233886, 233890, 233894, 233898, 233902, 233906, 233910, 237890, 237894, 237898, 237902, 237906, 237910, 241890, 241894, 241898, 241902, 245898, 245902). These medium resolution true color images are considered the new "basemap" for the Commonwealth by MassGIS and the Executive Office of Environmental Affairs (EOEA). MassGIS/EOEA and the Massachusetts Highway Department jointly funded the project. The photography for the mainland was captured in April 2001 when deciduous trees were mostly bare and the ground was generally free of snow. The geographic extent of this dataset is the same as that of the MassGIS dataset: Boston, Massachusetts Region LIDAR First Return Elevation Data, 2002 [see cross references].
