The digital natural color aerial imagery was acquired in spring 2006 using a DMC sensor flown at a nominal height of 9,600 feet AMT (Above Mean Terrain). ABGPS data was also collected supplemented by New York State CORS data. Digital imagery was reviewed for completeness and, after any adjustments, approved by CSCIC. The Ground Control used to support the digital natural color ortho imagery production was collected by identifying strategic points on previous aerial photography then determining the coordinates by ground survey techniques. The new Ground Control was supplemented by targeting of existing control monuments from previous years orthoimagery production and by existing HARN station data. The Digital Aerial Triangulation (DAT) was performed, primarily, using softcopy workstations and Intergraph's ISPM software. DAT solutions were independently reviewed and checked using blind control points. Digital Elevation Models (DEM) (masspoints and breaklines) used to support ortho imagery production were created using standard photogrammetric collection techniques on Intergraph's SSK soft copy workstations. A combination of new DEM and densified DEM from previous years work were produced.The images were then ortho rectified using Intergraph's OrthoPro software. Color balancing was performed using both Intergraph's OrthoPro software and Orthovista. Seamless mosaicing was performed by automatic and manual seamline creation using Intergraph's IRASC software and then importing them into OrthoPro for mosaicing. Images were then color balanced and quality controlled using Intergraph's IRASC, OrthoPro and Adobe PhotoShop software. Mosaics are color and tone balanced over the entire county and between counties. 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. 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 v8.0 software. All j2ps required MapInfo TAB files and ESRI AUX files.
