The Digital Natural Color aerial imagery was acquired in spring 2007 using a DMC sensor flown at a nominal height of 4500 feet AMT (Above Mean Terrain). ABGPS data was also collected to supplement New York State CORS data. High level photography was collected at a nominal height of 20,000 ft AMT, to tie the disjoining smaller islands on the low level photography with the main land. The Ground Control used to support the Digital Natural Color 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 ISPM / ISAT software or BINGO where applicable. 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 updated from the existing terrain data from year 2004 using standard pothogrammetric collection techniques on Intergraph's SSK soft copy workstations. The images were then ortho-rectified using Intergraph's OrthoPro software. Radiometric adjustment for the ortho rectified images was performed using both Intergraph's OrthoPro software and Orthovista. Seamless mosaicking was performed by automatic and manual seam line creation using Intergraph's Orthopro & IRASC software and then importing them into OrthoPro for mosaicking. Images were then color balanced again in order to match adjacent counties projects and quality controlled using Intergraph's IRASC, OrthoPro and Adobe PhotoShop software. The seamless mosaic was clipped into tiles using OrthoPro 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). Final files were then compressed to JPG2000 files (.jp2) with corresponding world files (.j2w) at a compression ratio of 20:1 using Lizard Techs GeoExpress v6.0 software. All .jp2's require MapInfo .tab files.
