display:none"> <I>Process description: </I>The Digital Natural Color aerial imagery was acquired in February 2009 using a DMC sensor flown at a nominal height of 4800 feet AMT (Above Mean Terrain). Raw imagery post-processed as 24 bit color RGB using Intergraph's DMC PPS software. ABGPS data was also collected, supplemented by Client Ground Control using existing photo identifiable points (PID). The Digital Aerial Triangulation (DAT) was performed using softcopy workstations and Intergraph's ISPM software. Digital Elevation Models (DEM) (mass-points and break-lines) used to support ortho imagery production were supplied by Client and updated as needed by MJH and created using standard photogrammetric collection techniques on Intergraph's soft copy workstations. The images were then ortho-rectified and using Intergraph's OrthoPro software. Color balancing was performed using both Intergraph's OrthoPro software and Orthovista. Seamless mosaicking was performed by automatic and manual seam line creation using Intergraph's 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). Control Surveys: Control planned and Surveyed by: Client (supplying existing control frm1997 &amp; 2006). Control supplemented with Airborne GPS IMU and data from two base stations.
