Pennsylvania Spatial Data Access (PASDA) is the official public access geospatial information clearinghouse for the Commonwealth of Pennsylvania and has served for twelve years as Pennsylvania's node on the National Spatial Data Infrastructure, Geospatial One-Stop, and the National Biological Information Infrastructure.
PASDA was developed by the Pennsylvania State University as a service to the citizens, governments, and businesses of the Commonwealth. PASDA is a cooperative project of the Governor's Office of Administration, Office for Information Technology, Geospatial Technologies Office and the Penn State Institutes of Energy and the Environment of the Pennsylvania State University. Funding and support is provided by the Pennsylvania Office for Information Technology, Geospatial Technologies Office. In addition, PASDA also receives substantial support from the Pennsylvania State University.

The Pennsylvania Imagery Navigator was developed to provide easier access to imagery and raster data such as topographic maps.The Navigator still
maintains all the functions of the Imagery Viewer and Download Utility. Note: To access the previous Imagery Viewer and Download Utility, click here. However, the enhanced Navigator allows users to print the map image, identify and download
multiple tiles for an area of interest, and new options for specifying area of interest.
