  1. Title: A Map of Lewis and Clark's Track, Across the Western Portion of North America From the Mississippi to the Pacific Ocean; By Order of the Executive of the United States, in 1804, 5 & 6. Copied by Samuel Lewis from the Original Drawing of Wm. Clark. Smal. Harrison fct (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced image of a map of the track of Lewis and Clark in the western United States, created in 1804. The original map appears in 'History Of The Expedition Under The Command Of Captains Lewis And Clark, To The Sources Of The Missouri, Thence Across The Rocky Mountains And Down The River Columbia To The Pacific Ocean. Performed During The Years 1804-5-6. By order of the Government Of The United States. Prepared For The Press By Paul Allen, Esquire. In Two Volumes. Vol. I. Philadelphia: Published By Bradford And Inskeep, New York. J. Maxwell, Printer. 1814 ... Vol. II.'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.

  2. Title: Zambian 2006 to 2010 Constituency and Ward Boundaries

    Contributors:

    Summary: This polygon shapefile represents best estimates of ward and constituency boundaries in Zambia based on available sources. The primary source for this layer is a set of printed maps of 2006-2010 ward and constituency boundaries provided by the Election Commission of Zambia (ECZ) to the author. However, these printed maps had three issues: (1) The packet was incomplete (maps for some constituencies and districts showed planned post-2010 ward boundaries rather than 2006-2010 actual wards); (2) The different layers in the file -- boundary edges, geographic features, and city locations -- had misalignments in many places, making it impossible to use geographic features for geo-referencing; (3) Some (small) wards could not be distinguished from one another in the printed maps. As a result: (1) Not all wards are included (see ward names and codes in the attribute definitions); (2) Georeferencing was primarily accomplished by matching stretches of constituency boundaries in the 2006-2010 maps with those in a Zambian Central Statistics Office-provided map of constituency and ward boundaries from the 2001-2005 period that had clearly not been changed between 2005 and 2006. Some additional inferences were made using of satellite maps of rivers and cities where boundaries were clearly drawn to follow rivers or large roads; (3) some wards have been merged into single polyons. This dataset is intended for researchers, students, policy makers and the general public, for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analysis with other spatial data.

  3. Title: (Composite Map) (Facsimile) Rocque's Map of London. 1746 (Raster Image)

    Contributors:

    Summary: This raster layer is a georeferenced image of a map titled "Composite Map: (Facsimile) Rocque's Map of London. 1746." Published in 1919, this composite map is considered one of the best facsimiles of the original Rocque Map ("A plan of the cities of London and Westminster, and borough of Southwark"), created by John Rocque and first published in 1746. A scanned version of this map available from The David Rumsey Map Collection was georeferenced by the Kindred London mapping project. The broad goal of the Kindred London project is to create four digitized road networks from four historic maps of London that will be used for an online, interactive web platform that will allow users to experience what it would have been like to travel the streets of London.

  4. Title: Impervious Areas, Cayuga Lake watershed, 2003

    Contributors:

    Summary: This dataset delineates impervious surfaces within the Cayuga Lake Watershed. However, the current dataset is limited to Cayuga County. These polygons were digitized from aerial imagery from 2003, using a combination of automatic and manual methods. This geographic dataset was developed by the Cayuga Lake Watershed Network as part of a larger project, in conjunction with Dr. Douglas Haith and Cornell University, to model nutrient loading in the Cayuga Lake watershed. The model used is the Generalized Watershed Loading Function (Haith and Shoemaker, 1987). Haith, D.A. and L.L. Shoemaker, 1987. Generalized Watershed Loading Functions for Stream Flow Nutrients. Water Resources Bulletin, 23(3), pp. 471-478.

  5. Title: Philadelphia, Pennsylvania, 1750 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: A map of Philadelphia and parts adjacent : with a perspective view of the State-House, by N. Scull and G. Heap. Facsimile of a 1750 map republished by Benj. R. Boggs in 1893. Scale [ca. 1:65,000]. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Pennsylvania South State Plane Coordinate System NAD83 (in Feet) (Fipszone 3702). 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, drainage, selected rural buildings with occupants' names, and more. Relief is shown pictorially. Includes text, distance table, ill., and ground-level view of the Statehouse (later Independence Hall). Facsimile of state showing estate of Wm. Allen near Germantown with his name added to the 'Table of distances'. 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.

  8. Title: Land Use and Land Cover, Cayuga Lake watershed, 2004

    Contributors:

    Summary: The dataset depicts land use/cover in the Cayuga Lake Watershed. This geographic dataset was constructed using a multi-resource approach. To map small scale land uses, high resolution aerial imagery available from the New York State Digital OrthoimageryProgram (NYSDOP) was interpreted by a trained GIS analyst according to a multi-tiered classification scheme similar to that used by Tompkins County, New York to map land use in 1995. To map large scale land uses and land cover types, two sets of Landsat Thematic Mapper images were analyzed. One set was analyzed by the USDA National Agricultural Statistics Service Research and Development Division, and published as the Cropland Data Layer for the state of New York. To distinguish between different forest cover types, Landsat-5 TM images were radiometrically and geographically corrected, and analyzed using a supervised classification procedure. These separate layers were overlayed to produce the final vector layer. This geographic dataset was developed by the Cayuga Lake Watershed Network as part of a larger project, in conjunction with Dr. Douglas Haith and Cornell University, to model nutrient loading in the Cayuga Lake watershed. The model used is the Generalized Watershed Loading Function (Haith and Shoemaker, 1987). Haith, D.A. and L.L. Shoemaker, 1987. Generalized Watershed Loading Functions for Stream Flow Nutrients. Water Resources Bulletin, 23(3), pp. 471-478.
