Peterburga, 1834]. It was published in 1834. Scale [ca. 1:76,000]. Covers Saint Petersburg Region, Russia. Map in Russian and Swedish.The image inside the map neatline is georeferenced to the surface of the earth and fit to the 'Pulkovo 1995 Gauss Kruger Zone 6N' 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, built-up areas and selected buildings, ground cover, and more. Relief is shown by hachures. Depths shown by soundings. Includes insets: [Retusari island] -- [Sluselberg]. 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. 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. 1834 source map publication date Complete None planned 30.013108 30.875309 60.041712 59.669749 LCSH Maps Human settlements Cities and towns Land use Landforms Infrastructure (Economics) Transportation Bodies of water ISO 19115 Topic Category imageryBaseMapsEarthCover GNS (NIMA) Russia Saint Petersburg None For educational, non-commercial use only.

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. For instance, this raster image was georeferenced to another georeferenced image, which may have its own positional inaccuracies (see "Process Steps"). 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 211.03295 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. 1834 map S.l. s.n. 1 map ; 44 x 50 cm. 76000 paper 1834 publication date Paper Map Source map for raster image Production of this raster image began with the scanning of the paper map on a high-resolution scanner: (Betterlight, Super8K2 scanning back camera and ViewFinder 5.x capture software). Maps were photographed at a copy stand. A vacuum easel was used to keep the maps flat during photography. The imaging specification was designed to produce detailed "Archival Master" images that, to the extent possible, are faithful reproductions of the originals, and that allow for highly detailed screen reproduction and print reproduction at up 1:1. Images in this collection were processed using Adobe Photoshop. Color and tonal corrections were made using Adobe Photoshop. Image files were viewed on a calibrated monitor. Editing was performed in an ISO 3664 compliant proofing environment. Master Image files were corrected and archived as TIFF files in the sRGB IEC611966-2.1 color-space. When possible files were batch processed using an "action" script derived from edits applied to match a representative sample.

Cambridge MA 02138 USA 617-495-2030 Using ArcMap 9.2 software, the digital TIFF image was georeferenced to common points located on the following scanned, georeferenced paper map: Leningrad (1:35,000) published by the U.S. Central Intelligence Agency in 1956. This map was scanned at 300 dpi and then georeferenced to four sets of UTM coordinates (closest to the corners) in the 'European Datum 1950 UTM Zone 36N' coordinate system with an RMS error of 10.49738 meters. The digital TIFF image was georeferenced to the above-listed map using the 'Pulkovo 1995 Gauss Kruger Zone 6N' coordinate system. In addition to the above-listed map, this TIFF image was also georeferenced to points located on the following digital vector file: ESRI Data and Maps 2006 Europe Major Rivers (1:25,000), and to the following previously georeferenced digital image: "Plan Kronshtatsko bukhty s S. Peterburgom" published in 1855 (georeferenced by the Harvard Map Collection with a resulting RMS error of 175.44826. A world file (.tfwx) and an .aux.xml file were automatically generated and saved in association with the digital TIFF image. See 'Horizontal Accuracy' for the RMS error of this TIFF image. Please note that the projection will need to be defined by the user in order to display the image with other projected data and the world file will need to be stored in the same root directory as the image.

The colors on that sheet can represent relief, drainage, vegetation, populated places, cultural features, coastal hydrography, transportation features (roads, railroads, tracks and trails), spot elevations and boundaries. The colors are sometimes explained in a legend that is incorporated into the map inset or collar. Not applicable. Harvard University Library Harvard Geospatial Library mailing and physical address
