  Abstract:  Digital orthophotography of New Jersey in State Plane Coordinate System NAD83 Coordinates, U.S. Survey Feet. Multi-spectral digital orthophotography was produced at a scale of 1:2400 (1"=200') with a 1 foot pixel resolution for The State of New Jersey totaling approximately 8,162 square miles. A redelivery of major urban areas in 2009 incorporates off-axis-flight images captured in 2007 and 2008. See process step for details, and browse graphic for map of areas.Digital orthophotography combines the image characteristics of a photograph with the geometric qualities of a map. Digital orthophotography is a process which converts a digitized perspective aerial photograph or other remotely sensed image data to a digital product that has been rectified for camera lens distortion, vertical displacement caused by terrain relief and variations in aircraft altitude and orientation. Aerial photography of the entire State of New Jersey was captured during March-May, 2007. Two flight dates (4-30-07 and 5-3-07) were rejected from the original 2007 flight due to excessive leaf conditions. Spring 2008 re-flights were planned and acquired in three missions dating: April 3rd, 10th and 15th of 2008. The final orthophotos for parts of Warren, Hunterdon, Sussex, Passaic, Essex, Union and all of Bergen and Hudson Counties were created utilizing both years of imagery. The DMC large format digital camera captures four band (RGB and NIR) imagery at 12 bits per pixel. For software compatibility a linear stretch was applied to expand the bit depth from 12 to 16 in order to facilitate the display of the imagery in ArcGIS. 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 was derived from 16-bit, 4-band (RGB and NIR), uncompressed, GeoTIFF images and consists of ortho photo tiles adhering to the State of New Jersey's 5,000 x 5,000' ortho photo tile index formatted as compressed, 8-bit, 4-band (RGB and NIR), orthophoto image tiles in lossy JPEG2000 (at 10:1 compression).
  Purpose:  Aerial survey of the State of New Jersey. Orthophotos serve a variety of purposes, from interim maps to field references for earth science investigations and analysis. The digital orthophoto is useful as a layer of a geographic information system and as a tool for revision of digital line graphs and topographic maps.
  Supplemental Information:  Reprocessed tiles of limited parts of the state were delivered in two batches in spring of 2009, and several batches in fall of 2009. The reprocessing was done using imagery collected in 2007 and 2008. See Process Steps and Browse Graphics for details.
