  1. Title: San Francisco, California, Earthquake and Fire, 1906 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: [San Francisco, California, showing the area destroyed by fire, April 18-21, 1906]. It was published by R.J. Waters & Co. in 1906. Scale [ca. 1:21,000]. Covers the northeastern portion of the city showing burnt district in red. The image inside the map neatline is georeferenced to the surface of the earth and fit to the California Zone III State Plane Coordinate System NAD83 (in Feet) (Fipszone 0403). 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 the burnt district, roads, drainage, selected public buildings, wharves, and more. Relief shown by contours. 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.

  4. Title: The environs of London. Drawn & engraved by H. Waters. Published by Baldwin & Cradock, Paternoster Row, under the superintendence of the Society for the Diffusion of Useful Knowledge, February 1st, 1832. (London: Chapman & Hall, 1844) (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced image of a map of London and the surrounding area. The original map appears in in 'Maps of the Society for the Diffusion of Useful Knowledge. London: Chapman and Hall, 186, Strand. 1844'The historic map layers in the Google Earth Rumsey Map Collection have been selected by David Rumsey from his large collection of historical maps, as well as some from other collections with which he collaborates. All the maps contain rich information about the past and represent a sampling of time periods, scales, and cartographic art, resulting in visual history stories that only old maps can tell. Each map has been georeferenced by Rumsey, thus creating unique digital map images that allow the old maps to appear in their correct places on the modern globe. Some of the maps fit perfectly in their modern spaces, while othersgenerally earlier period mapsreveal interesting geographical misconceptions of their time. Cultural features on the maps can be compared to the modern satellite views using the slider bars to adjust transparency. The result is an exploration of time as well as space, a marriage of historic cartographic masterpieces with innovative contemporary software tools.
