Abstract
This layer is a georeferenced raster image of the historic paper map entitled: Plan of the city of Charlestown, by Felton Parker [and] Ebenr. Barker. It was published by J.H. Bufford's Lithogy. in 1848. Scale [1:4,800]. Covers the populated place Charlestown (Boston, Massachusetts) and also parts of Somerville, Cambridge, Boston, and East Boston. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Massachusetts State Plane Coordinate System, Mainland Zone (in Feet) (Fipszone 2001). 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 shows features such as roads, railroads, drainage, wharves, public buildings, schools, churches, cemeteries, city ward boundaries and more. It also includes an index to points of interest. This layer is part of a selection of digitally scanned and georeferenced historic maps of Massachusetts from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of regions, originators, ground condition dates (1755-1922), scales, and purposes. The digitized selection includes maps of: the state, Massachusetts counties, town surveys, coastal features, real property, parks, cemeteries, railroads, roads, public works projects, etc.
Purpose
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.

Data Quality Information
Attribute Accuracy Report
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.
Completeness Report
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
Horizontal Positional Accuracy Report
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, but in most cases, these are small compared with sources of error in the original map graphic. One source of error could be associated with the fact that this image is referenced to the Massachusetts State Plane (Feet) coordinate system, which is inconsistent with the original projection of the paper map, and may lead to discrepancies in the horizontal accuracy of the raster image. The RMS error for this map is 18.91572 feet. 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.

Entity and Attribute Information
Entity and Attribute Overview
The indexes reference a color palette of RGB values from 0 through 255, representing the color value from the original paper sheet map. 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.
