Orthoimagery from the New York Statewide Digital Orthoimagery Program (NYSDOP), and the USGS National Aerial Photography Program (NAPP), which covered New York between 1994 and 1999, is available through this site. Orthoimagery is presented by year flown. As a default, the most recent NYSDOP imagery is displayed. Users can turn layers off and on to see different vintages of imagery. More information on the programs creating the imagery can be obtained from the orthoimagery pages on the NYS GIS Clearinghouse site.
