The position and orientation of the aircraft was recorded at each exposure with the on-board global positioning system (GPS) and inertial measuring unit (IMU).2011-05-24Flight PlanAerial PhotographyIMU Orientation DataGPS Position DataMosaic Process: Inpho OrthoVista software was used to color-balance, automatically generate seamlines, and mosaic the individual orthophotos into user defined mosaic tiles.2011-11-21Digital Orthorectified Aerial PhotographyInitial Orthorectified Mosaic TilesOrthorectification Process: Inpho OrthoMaster software was used to process the imagery to remove systematic and terrain distortions while also georeferencing it.
