PCI Geomatica 2016 SP2 he Air Photo Ortho Suite and ADS Ortho Suite both include rigorous models used to correct the geometry of analogue and digital cameras and to produce orthorectified air photos. These models compensate for the effects of varying terrain and for the distortions inherent to a camera , such as the curvature of the lens, focal length, perspective effects, and the camera’s position and orientation. The computed math model calculates the camera’s position and orientation when an image is taken. Module Prerequisites The Air Photo Ortho Suite and ADS Ortho Suite are add -on packages to Geomatica. They require Geomatica Core or Geomatica Prime as a pre -requi site. Supported Air Photo Formats Geomatica supports the following aerial image formats in Air Photo Ortho Suite (Standard and Digital/Video) and ADS Ortho Suite (ADS): Standard These are images scanned from film or prints. These images often measure 9 inches by 9 inches in size and usually contain calibration (fiducial) marks. Normally, a camera calibration report is supplied with the images. The camera calibration report provides data about the camera; such as the focal length, fiducial coordinates and radial distortion parameters. Digital/Video These are images generated from CCD arrays (Charged Coupled Devices) in digital cameras. A camera calibration report may not be supplied with the images. Most companies that provide calibration services for standard aerial cameras can provide camera calibration services for digital and video cameras. The minimum required parameters are focal length (determined when the lens is set) and chip size (which can be obtained from the camera manufacturer). Oblique imager y is not supported. Leica Airborne Digital Sensor ( ADS ) The Leica airborne digital sensor (ADS) is a line- scanning sensor that collects images in l ong strips up to 24,000 pixels wide. This camera can simultaneously collect panchromatic, color, infrared and stereo imagery. All multispectral bands are collected simultaneously providing five- band, co- registered imagery at a common, high resolution
