{ "currentVersion": 10.71, "serviceDescription": "Under contract with the State of Michigan, Vexcel was contracted to produce and deliver natural Color (RGB) orthophotos for numerous areas of interest in support of Michigan's Statewide Partnership Program. Areas of interest were defined by the State. All aerial imagery was acquired using ADS direct digital sensors at an altitude sufficient for the production of digital orthophotos with a 1.0-foot or .5-foot pixel resolution as requested. Following acquisition of imagery data, survey ground control coordinates were used in-conjunction with Airborne GPS and Inertial Measurement Unit (IMU) information to establish precise spatial positioning of the image data through the process of Analytical Aero-Triangulation (AT). Upon completion of AT, the imagery was rectified to the best available digital elevation model (DEM), whether from the USGS, other high quality DEM provided by the participating government in GeoTIFF or other compatible format, or new ADS stereo imagery compiled and edited surface model using Pictovera software. The resultant rectified imagery was analyzed and radiometrically adjusted to provide the state with optimal color and tonal appearance. Manually-placed seamlines were generated to mosaic imagery from adjacent flightlines. Following mosaicking and color-balancing, multiple QA/QC processes were performed to insure optimal data quality was achieved prior to tiling the data to 5,000 by 5,000 pixel extents. All ortho tiles were clipped to an AOI shapefile (buffered to 400-meters) boundaries, as supplied by the State of Michigan. Final ortho tiles were delivered in the requested projection/units and in GeoTIFF format.", "name": "ImageServices/EnterpriseOrthoTC2012ImageService", "description": "Under contract with the State of Michigan, Vexcel was contracted to produce and deliver natural Color (RGB) orthophotos for numerous areas of interest in support of Michigan's Statewide Partnership Program.
