NJ Orthophoto High Resolution Mosaics
Flight Dates: 2002 Resolution: 1ft Projection: UTM NAD 83 Color: CIR General Description: Digital color infrared (CIR) orthophotography of New Jersey in UTM NAD83 Coordinates, U.S. Survey Feet. The digital orthophotography was produced at a scale of 1:2400 (1"=200') with a 1 foot pixel resolution. Digital orthophotography combines the image characteristics of a photograph with the geometric qualities of a map. Digital orthophotography is a process which converts aerial photography from an original photo negative to a digital product that has been positionally corrected for camera lens distortion, vertical displacement and variations in aircraft altitude and orientation. Aerial photography of the entire State of New Jersey was captured during February-April, 2002. The ortho-rectification process achieved a +/-4.0 ft. horizontal accuracy at a 95% confidence level, National Standard for Spatial Data Accuracy (NSSDA). This dataset consists of 5000' x 5000' files in MrSID format with a 15:1 compresssion ratio. The files were produced utilizing MrSID Geospatial Edition 1.4 and are approximately 5 MB in size. |
