The purpose of this project was to develop a web based index of historical railroad valuation maps for the Erie Lackawanna Historical Society (ELHS). The ELHS was in possession of a complete collection of over 3600 scanned 1918 railroad valuation map for the Erie Railroad, however these scanned maps lacked spatial reference. The first step in making these maps usable in modern GIS was to georeference them using Esri’s ArcGIS. Once the maps were georeferenced, they were organized into a geodatabase, along with additional supporting layers, as well as geotagged historical photos relating to the railroads. In order to make these maps and data available to a wider audience, an interactive web application was developed using HTML, CSS, and Esri’s ArcGIS API for JavaScript, which allows users to view the georeferenced maps as a fully mosaicked map layer, or access the original maps and photographs individually or in bulk.
