Abstract:
A scope of work was developed in response to a request by the U. S. Army Corps
of Engineers, Philadelphia District. The request was to perform a topographic
change grid analysis for the Frankford 7.5-minute quadrangle, 1:24,000-scale
topographic map, which includes the Wissinoming neighborhood, and the Germantown 7.5-minute quadrangle, which includes the Logan and Feltonville neighborhoods of the City of Philadelphia. The following tasks were performed under this scope of work: A GPS-corrected GIS grid analysis for each quadrangle was completed and is accompanied by documentation that describes procedures and provides metadata of the informational content of the GIS. A high-resolution global positioning system (GPS) survey was conducted for each topographic quadrangle in order to evaluate and correct systematic discrepancies in elevation between the modern and historic surveys. Prior to release, the fully documented GPS-corrected GIS grid analysis for each quadrangle was reviewed for (1) com-pleteness of documentation and for (2) appropriate analysis and discussion of uncertainties.
The following report is in fulfillment of the tasks outlined in this scope of work and was performed by the U. S. Geological Survey for the U. S. Army Corps of Engineers, Philadelphia District under MIPR agreement number: W25PHS93358288.
Purpose:
The U.S. Geological Survey (USGS), working in cooperation with the U. S. Army Corps of Engineers (ACOE), Philadelphia District, has conducted a study of topographic change throughout the Frankford and Germantown 7.5 minute USGS quadrangles, Philadelphia and Montgomery Counties, Pennsylvania and Burlington County, New Jersey. The purpose of this study is to determine the spatial extent of human-induced topographic change during the past 100 years. The USGS has conducted this study in response to severe structural damage and subsequent condemnation of houses within the Philadelphia city limits, due to differential subsidence of fill material within buried stream valleys.
