Image pixel size is one-half-foot (0.5') ground sample distance (GSD). Image horizontal accuracy is within two feet (2') at the 95% confidence level (NSSDA). This image was compiled from individual image tiles covering 2000 ft. by 3000 ft. on the ground. This digital Ortho-imagery can serve a variety of purposes, from general planning to field reference for spatial analysis to a tool for revision of vector maps. It can also serve as a reference layer for GIS.

The file naming convention was supplied by New York State. When the ortho tiles were created the file names were restricted to a numeric value representing the lower left corner of the ortho tile. These tiles were then all renamed using a batch script so that they reflected the N.Y. state standard (i.e. "c_10470162_12_09600_4bd_2009.tif"). Consistency of file naming was ensured by using a batch process. The file naming convention consists of the first letter for Central, East, West or Long Island for New York State Plane Coordinate Systems (NYSPCS). The following four numeric characters represent the first four characters of the "X" coordinate value for the tile's lower left corner coordinate in NYSPCS and the next four characters represent the first four characters of the "Y" coordinate value for the tile's lower left corner coordinate in NYSPCS. The next two numeric characters represent the tile's Ground Sampling Distance (GSD) value in ft. The following five numeric characters represent the Above Mean Terrain (AMT) nominal height at which the DMC sensor recorded or collected the original imagery for the corresponding area. The next three characters are "4bd" for 4-band ortho-photos. Lastly, the last four numeric digits represent the year in which the particular ortho was created. The project consisted of 2506 final tiles. The Digital Natural Color aerial imagery was acquired in Spring 2009 using a DMC sensor flown at a nominal height of 9,600' AMT (Above Mean Terrain). ABGPS data was also collected and processed using POSPac (version 5.1) Mobile Mapping Suite . The Ground Control used to support the 4-band ortho-imagery production was collected by identifying strategic points on previous aerial photography and supplemented by selecting new points or photo identifiable points (PID) in areas where needed due to a lack or minimal existence of points from previous ortho-imagery production projects and then determining the precise location coordinates of the entire ground control network by using ground survey techniques. The new Ground Control Network was also supplemented by targeting existing New York State HARN stations data. The Digital Aerial Triangulation (DAT) was performed, primarily, using softcopy workstations and Intergraph's ISAT. DAT solutions were independently reviewed and checked using independent blind control points. Digital Elevation Models (DEM) (mass-points and break-lines) used to support ortho imagery production were supplied by the state and updated using standard photogrammetric collection techniques on Intergraph soft copy workstations, and/or collected as LiDAR during spring 2009. The images were then ortho-rectified using Sanborn's proprietary APS orthophoto software modules. Color balancing, seamless mosaicking was performed by automatic and manual seam line creation steps, final color balancing and final extractions were also accomplished using this software. A final tile by tile quality control was performed using Adobe PhotoShop software. The imagery product deliverables are GeoTIFF images with embedded header information describing the required projection, pixel size, tile size and other related data and corresponding world files (.tfw). Derivative compressed imagery is also available in JP2000 format. Shawn Benham Sanborn Map Company Inc.
