Service Description: 1855 Map of the city of Pittsburgh with some of the surrounding communities. This map service includes a mosaic of several volumes of plat maps that were originally bound atlases. The mosaic was created using ArcGIS software from the scanned JPEG images, varying from 300-600 dpi. These images were obtained from the Historic Pittsburgh website (http://historicpittsburgh.org/maps-hopkins) The images were georeferenced to WGS84 Web Mercator and the borders were clipped to create a contiguous map.

This product is to be used for reference purposes only. The original historical paper maps were sometimes damaged or distorted to varying degrees due to age and use. There are spatial inaccuracies and some places where the footprints do not lineup perfectly or in some cases overlap.
