A historical overview of Allentown and the Lehigh Valley, using Sanborn Maps. For example, the land where Building 21 now sits was previously occupied by tanneries and silk mills, and the Little Lehigh was used for waste disposal, carrying away effluents from these businesses and the surrounding residences. We will assemble layers of historical maps as a kml file to be displayed in Google Earth or other viewer. These maps will be organized both chronologically (illustrating different eras) and thematically, noting changes in the economy, demography, and ecology. Accompanying materials will also note changes in civic leadership during each era.

A dataset on the fragmentation of ASD. Contemporary maps of school districts in the Lehigh Valley hint at the dissolution of urban districts, as suburban areas have broken away. This trend is especially visible with ASD, which lost its entire western half to Parkland and parts of its southern end to Salisbury. (See image at right.) The completed dataset will show the devolution of ASD from the 1960s to the present day, with accompanying demographic data. The final result will be presented as a set of layers in Lehigh’s institutional account at ArcGIS.com
