High Resolution Digital Orthoimagery 2000 - 2012
The purpose of the Statewide Digital Orthoimagery Program (DOP) is to produce high-resolution digital orthoimagery for the State of New York on an ongoing annual basis. It is anticipated that the entire state will be covered every 3-5 years. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. The DOP will include data collection, data processing, and quality assurance/quality control. The specific goals of the Program are:
- Cover 25-33% of the State with new digital orthoimagery every year
- Produce accurate natural color1 digital orthoimagery for urban areas at a resolution of one (1) square foot on the ground
- Produce accurate natural color1 digital orthoimagery for non-urban areas at aresolution of two (2) square feet on the ground.
- Allow for upgrades of the requirements for the orthoimagery in consideration of county and local government needs (e.g., sub-1 foot resolution and 1 foot resolution in non-urban areas)
- Serve up both the new and historical digital orthoimagery for free public access through the New York State GIS Clearinghouse.
The DOP produces data being used extensively by State agencies, counties, local governments, federal agencies, the private sector, the academic sector, and by ordinary citizens. Applications include economic development (web site features, site evaluations, etc.), real property inventory and assessment, infrastructure planning, natural resource inventory and planning, and general visual "backdrop" reference for other GIS layers of information. It is also used for the creation and updating of mapping features easily identifiable from the orthoimagery. The DOP is also producing a historical record that will be available for many years to come.
1 NOTE: Beginning in 2008, ALL imagery will be 4-band orthoimagery capable of both natural color and color infrared display. The base product is still 1 ft resolution in urban areas and 2 ft resolution in non-urban areas.
