Paris, France, 1855 (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: Nouveau plan complet de Paris avec ses fortifications : divisé en 12 arrondissements & 48 sections avec les principaux monuments en elévation, donnant la distance légale en mètres des forts détachés aux murs d'enceinte & aux murs d'octroi indiquant la population & les fêtes patronales des environs de Paris, gravé sur acier par J.N. Henriot. It was published by chez A. Bes et F. Dubreuil in 1855. Scale [ca. 1:16,700]. Map in French. Covers Paris, France.The image inside the map neatline is georeferenced to the surface of the earth and fit to the European Datum 1950, Universal Transverse Mercator (UTM) Zone 31N 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 roads, railroads, railroad stations, drainage, selected buildings and built-up areas, ground cover, district boundaries, fortification, parks, gardens, cemeteries, and more. Relief and some buildings shown pictorially. Includes also indices, notes, and inset: Environs de Paris indiquant tous les Forts.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.

Historic paper maps can provide an excellent view of the changes that have occurred in the cultural and physical landscape. The wide range of information provided on these maps make them useful in the study of historic geography, and urban and rural land use change. As this map has been georeferenced, it can be used in a GIS as a source or background layer in conjunction with other GIS data.

The georeferenced raster is a faithfully reproduced digital image of the original source map. Some differences may be detected between the source graphic used and the raster image due to the RGB values assigned that particular color. The intent is to recreate those colors as near as possible. Data completeness for raster digital image files reflect content of the source graphic. Features may have been eliminated or generalized on the source graphic due to scale and legibility constraints 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 18.52104 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.
