Photogrammetry I

After the completion of this course, students should have the ability to: 1. identify types of photogrammetry and relationship between photogrammetry and land surveying; 2. explain working principles, uses and properties of photogrammetry instruments; 3. use photogrammetry camera and process data collected therefrom; and 4. interpret photogrammetry products.

General introduction to photogrammetry. Relationship of photogrammetry to land surveying, Remote sensing and GIS. Aerial and terrestrial photogrammetry. Classical and digital photogrammetry. Application areas of photogrammetry. Components of photogrammetric camera, photographic processes, distortions and resolution of film-based camera. Working principles and properties of digital cameras. Aerial Photography: classification according to camera axis inclination, angular coverage and photographic materials. Geometry of photographs. Image and object space and coordinate systems, photo scale, tilt, relief displacement and ground coverage. Photographs as perspective projections and difference from maps. Uses of stereoscopes, stereo-plotters (analogue, analytical and digital), comparators and ortho- projectors. Introduction to Photo Interpretation.
