What is PASDA

Pennsylvania Spatial Data Access (PASDA) is Pennsylvania's official public access geospatial information clearinghouse. PASDA was developed in 1996 by the Pennsylvania State University and has served as the clearinghouse for Pennsylvania for over twenty years.

PASDA is a cooperative project of the Governor's Office of Administration, Office for Information Technology, and 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.

Penn State contributions include system administration support and infrastructure from the Institute for CyberScience, and the College of Earth and Mineral Sciences.

Our Purpose

The purpose of PASDA is to serve as the Commonwealth's comprehensive and coordinated open geospatial data portal that provides free public access to geospatial data and information by, for, and about the Commonwealth of Pennsylvania.

PASDA is Pennsylvania's node on the National Spatial Data Infrastructure,Geospatial One-Stop, and is integrated with the National States Geographic Information Council GIS Inventory.

The Keystones of PASDA

PASDA is based on a long term vision that incorporates the ideas of free access to data, outreach, and service to our users and data providers in order to maximize the benefits to the citizens of the Commonwealth.

The keystones in the success of the program are:

PASDA will continue to provide free storage of geospatial data, as well as build partnerships that enhance ease of access and benefit the data provider, and to develop data access resources and innovative tools to enhance the use and benefits of geospatial data for all citizens of the Commonwealth and geospatial community.

The data made available through PASDA is provided by our data partners to encourage the widespread sharing of geospatial data, eliminate the creation of redundant data sets, and to further build an inventory (through the development and hosting of metadata) of available data relevant to the Commonwealth. PASDA serves as a resource for locating data throughout the Commonwealth through its data storage, interactive mapping applications, and metadata/documentation efforts.

PASDA services are provided free of charge to all users and data stakeholders. The data on PASDA is provided by federal, state, local and regional government agencies, non-profit organizations, and academic institutions throughout the region.

THANK YOU to our Data Partners and Sponsors!

PASDA would like to thank its many data partners and the geospatial community in Pennsylvania for helping to build one of the largest and most comprehensive geospatial data clearinghouses in the country and for supporting free access to data.

PASDA would not be possible without the participation of the data providers as well as the long term support of the Commonwealth, Office for Information Technology, and the Pennsylvania State University.
