The effective topographic mapping of the Commonwealth began in the late 1800s, shortly after the establishment of the US Geological Survey. The spatial-temporal pattern of expansion for the state's topographic coverage reflects the replacement of plane table surveying by modern photogrammetric mapping as well as Pennsylvania's internal priorities and its support of base mapping through a fifty-fifty federal-state cost-sharing program. -from Author
