The New Jersey Office of Information Technology recently unveiled the NJ Image Warehouse, a new Internet application that allows users to download statewide ortho photography.

"Ortho imagery combines the image characteristics of an aerial photograph with the geometric qualities of a map," said Bruce Harrison, state geographic information officer. "We built the NJ Image Warehouse so that this essential statewide mapping resource could be available to anyone with Internet access."

Visitors to the Image Warehouse can find and download individual 2002 ortho photo tiles and 1995 USGS quarter quads for anywhere in the state in several file formats. Using the set of mapping tools or the links provided in the application, users can highlight, zoom to, and then download imagery by geographic area -- street address, municipality or county -- or by actual tile or quarter quad number.

"As an essential element of New Jersey's spatial data infrastructure, up-to-date orthophotography is critical for homeland security and emergency response initiatives," said New Jersey Chief Technology Officer Charles S. Dawson.

This application also allows users to toggle between 2002 and 1995 imagery to see how one relates to the other.
