  1. Title: International Bathymetric Chart of the Arctic Ocean, 500-Meter Resolution GeoTIFF (Version 3.0)

    Contributors:

    Summary: This layer is a georeferenced image (GeoTIFF) of a digital bathymetric model (DBM) compiled with all multibeam, dense single beam and land data added at 500 x 500 meters resolution. The original (DBM) was compiled with all multibeam, dense single beam and land data added at 500 x 500 m resolution in a final step using the remove-restore method. Data were compiled from several multibeam cruises in the region dating from 1994 to 2011. The goal of this initiative is to develop a digital data base that contains all available bathymetric data north of 64° North, for use by mapmakers, researchers, institutions, and others whose work requires a detailed and accurate knowledge of the depth and the shape of the Arctic seabed.

  2. Title: International Bathymetric Chart of the Arctic Ocean, 30 Arc-Second Resolution GeoTIFF (Version 3.0)

    Contributors:

    Summary: This layer is a georeferenced raster image (GeoTIFF) of a digital bathymetric model (DBM) of the Arctic Ocean compiled with all multibeam, dense single beam, and land data added at a resolution of 30 x 30 arc seconds. This is a reprojected version (WGS84) of the 500 meter resolution data layer. The original (DBM) was compiled with all multibeam, dense single beam and land data added at 500 x 500 m resolution in a final step using the remove-restore method. Data were compiled from several multibeam cruises in the region dating from 1994 to 2011.

  4. Title: Spain/Portugal, 1828 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Spain and Portugal, by Sidney Hall. It was published by Longman, Rees, Orme, Brown & Green in 1828. Scale ca. 1:2,350,000. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Europe Lambert Conformal Conic 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, drainage, cities and other human settlements, territorial boundaries, shoreline features, and more. Relief shown by hachures. 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. The selection represents a range of originators, ground condition dates, scales, and map purposes.

  5. Title: Egypt (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of an historic regional map of Egypt originally engraved by Sidney Hall in the 19th century. 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 using a Transverse Mercator projection. 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 176.03 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.
