  1. Title: London, England, 1880 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Indicator map of London : with the recent improvements, 1880. It was published by C. Smith & Son in 1880. Scale [ca. 1:18,300]. The image inside the map neatline is georeferenced to the surface of the earth and fit to the British National Grid coordinate system (British National Grid, Airy Spheroid OSGB (1936) Datum). 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, built-up areas, selected buildings, Borough boundaries, parks, docks, and more. Relief is shown by hachures. Includes location tape. 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.

  6. Title: Global GIS : Gazetteer of populated places, Eastern Hemisphere

    Contributors:

    Summary: This datalayer is a point coverage representing a gazetteer of populated place features located between the Greenwich meridian (0 degrees) and 180 degrees east of the Greenwich meridian, encompassing the Eastern Hemisphere, excluding Antarctica. Features and attributes were derived from the GNS (GEOnet Names Server) and include populated place names. The GEOnet Names Server provides access to the National Geospatial-Intelligence Agency's (NGA) (formerly the National Imagery and Mapping Agency (NIMA)) database of foreign geographic feature names. Approximately 20,000 of the database's 3.5 million features are updated monthly with names information approved by the U.S. Board on Geographic Names (US BGN). The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.

  9. Title: Global GIS : Drainage Basins

    Contributors:

    Summary: This datalayer is a polygon coverage representing hydrologic drainage basins located worldwide. The data displayed here is derived from the HYDRO 1K Elevation Derivative Database. The drainage basins distributed with the HYDRO1k data set suite are derived using the vector stream networks along with the flow direction data set. Each polygon in the basin data set has been tagged with a Pfafstetter code uniquely identifying each sub-basin. HYDRO1k, developed at the U.S. Geological Survey's (USGS) EROS Data Center, is a geographic database providing comprehensive and consistent global coverage of topographically derived data sets. Developed from the USGS' recently released 30 arc-second digital elevation model (DEM) of the world (GTOPO30), HYDRO1k provides a standard suite of geo-referenced data sets (at a resolution of 1 km) that will be of value for all users who need to organize, evaluate, or process hydrologic information on a continental scale.

  11. Title: Global GIS : Geologic map (excluding the United States)

    Contributors:

    Summary: This datalayer is a polygon coverage showing U.S. Geological Survey defined geologic provinces of the World, excluding the United States. It was published as part of the USGS Global GIS : global coverage database (2003). The World Energy Assessment created geologic maps of 7 regions. These regions were joined with minimum edge matching or checking for feature description by the Global GIS team. The user is warned there will be discrepancies on bordering features. The regions are described in the Geologic Provinces of the World full metadata files. Canada, Mexico and Central America, and the Europe tiles were screen digitized by the Global GIS team. These were approximately located and should be used as a geologic guide. The US and Alaskan Geologic Maps were kept as separate layers to allow the use the apply their original legends. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million.

  18. Title: Global GIS : United States gazetteer, populated places

    Contributors:

    Summary: This datalayer is point coverage gazetteer representing populated places in the United States and its territories. It contains official names and locations of populated places (PPL) as defined by the U.S. Board on Geographic Names. It is derived from the Geographic Names Information System (GNIS) and was published as part of the USGS Global GIS : global coverage database (2003). The Geographic Names Information System (GNIS), developed by the U.S. Geological Survey in cooperation with the U.S. Board on Geographic Names (BGN), contains information about physical and cultural geographic features in the United States and associated areas, both current and historical, but not including roads and highways. The database also contains geographic names in Antarctica. The database holds the Federally recognized name of each feature and defines the location of the feature by state, county, USGS topographic map, and geographic coordinates. Other feature attributes include names or spellings other than the official name, feature designations, feature class, historical and descriptive information, and for some categories of features the geometric boundaries. The database assigns a unique feature identifier, a random number, that is a key for accessing, integrating, or reconciling GNIS data with other data sets. The GNIS is our Nation's official repository of domestic geographic feature names information. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.
