One of the smallest physiographic provinces in the state is confined to Philadelphia, Delaware, and Bucks counties along the Delaware River.Local relief is less than 200 feet (61 m) and much of the bedrock is buried under recent alluvial deposits. This is an artifact of the digital processing. The Pennsylvania Geological Survey’s most popular group of datasets -- Bedrock Geology of Pennsylvania (ZIP) -- consists of 1:250,000-scale ArcGIS shapefiles for geologic units, geologic contacts, dikes, and faults that were created and slightly modified from the materials used to produce the 1980 printed Geologic Map of Pennsylvania (ZIP). 7.

This computer file lists all the soil map units by soil series or land type and their acreage in the state. The map was compiled and published in a transverse mercator projection at 1:250,000 scale. The 1980 Pennsylvania state geologic map (Berg and others, 1980) shows the areal distribution of 194 bedrock geologic units. The GPR investigations were made stepwise, with a first interpretation without any other input data, to give a quick overview of the area. Menu & Reservations Make Reservations .

Kriging works by developing statistical measures of spatial autocorrelation of the variable to be mapped (the variate). As can be seen in the map and in the legend in Figure 4, some of the output values were 0 or a negative value, meaning that the modeled bedrock elevations were higher than DEM elevations.
