Summary: This layer is a georeferenced raster image of the historic paper map entitled: Plan kral. hlav. mesta Prahy a obci sousednich, sestavil a nakreslil Josef Bro ; ryl a tiskl V. Neubert. It was published by nakladem A. torcha Syna in 1900. Scale 1:12,000. Covers Prague, Czech Republic. Map in Czech.The image inside the map neatline is georeferenced to the surface of the earth and fit to the 'European Datum 1950 UTM Zone 33N' coordinate system. 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 and stations, street-railroads, drainage, built-up areas and selected buildings, ground cover parks, city districts and boundaries, and more. Includes inset: Prehledna mapa Velike Prahy.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.

Title: World (Ore deposits, 2003)
Contributors:- Point data
- 2003
Summary: Ore deposits.MRDS contains variable-length records of metallic andnonmetallic mineral resources of the world. A recordcontains descriptive information about mineral deposits andmineral commodities. The types of information in the database include deposit name, location, commodity, depositdescription, geologic characteristics, production,reserves, potential resources, and references. The MineralResource Data System master database is not accessible viathe WWW. The large number of multi-valued fields make itdifficult to import all the fields into a data format thatcan be utilized by the ArcView Internet Map ServerSoftware. This dataset contains all MRDS locations, butonly 44 of the possible 226 fields. A data structure wascreated in Access 97. Data was imported into the filestructure and then processed into Arc View, where it wastransformed into shape files that are used by the IMSsoftware to serve the MRDS data and permit access via the www.

Title: Geologic Units (Polygons): Generalized Geologic Map of Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands, 2005
Contributors:- Polygon data
- 2005
Summary: This polygon shapefile contains polygon boundaries, tags and labels for major geologic units in Alaska, Hawaii, Puerto Rico and the U.S. Virgin Islands. In addition to the polygons representing the areal extent of geologic units, it identifies major faults and continental glaciation in Alaska. The data depict the geology of the bedrock that lies at or near the land surface, but not the distribution of surficial materials such as soils, alluvium, and glacial deposits. This map complements the Generalized Geologic Map of the Conterminous United States by Reed and Bush. The data are generalized from a compilation prepared for use in the Geologic Map of North America, published as a paper map by the Geological Society of America and to be released as a digital file by the U.S. Geological Survey. This layer is part of the 1997-2014 edition National Atlas of the United States. These data have been prepared with a degree of detail appropriate for viewing at a scale of 1:7,500,000. Because of the degree of generalization required (generalization based on compilation scale), the data are intended primarily for display and for regional and national analysis, rather than for more detailed analysis in specific areas.

Title: Map of South Africa illustrating Dr. Livingstone's Discoveries (Raster Image)
Contributors:- Raster data
- 2013
Summary: This layer is a georeferenced image of an historic regional map of Southern Africa originally created by W. Pepper in 1858. The map illustratates the exploration routes of Dr. David Livingstone's journeys throughout Southern Africa. 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, or other information associated with the principal map. This map was scanned and georeferenced by the Stanford University Geospatial Center. This map is part of a selection of digitally scanned and georeferenced historic maps of Africa held at Stanford University Libraries. This historic paper map provides an historical perspective of the cultural and physical landscape during this time period. The wide range of information provided on these maps make them useful in the study of historic geography. As this map has been georeferenced, it also can be used as a background layer in conjunction with other GIS data. The horizontal positional accuracy of a raster image is approximately the same as the accuracy of the published source map. The lack of a greater accuracy is largely the result of the inaccuracies with the original measurements and possible distortions in the original paper map document. There may also be errors introduced during the digitizing and georeferencing process. In most cases, however, errors in the raster image are small compared with sources of error in the original map graphic. The RMS error for this map is 1059.81 meters. This value describes how consistent the transformation is between the different control points (links). The RMS error is only an assessment of the accuracy of the transformation.

Summary: This layer is a georeferenced raster image of the historic paper map entitled: Central Africa : on a scale of 1:10,000,000, By Dr. F. Boas. It was published by Hart & Von Arx in 1887. Scale 1:10,000,000 The image inside the map neatline is georeferenced to the surface of the earth and fit to the Africa Sinusoidal projected coordinate system. 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 drainage, cities and other human settlements, shoreline features, and more. Relief shown by shading. 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.
