Lecture On Photogrammetry Geometric Elements Ground Length Relief The course introduces the student to a globally applied tool known as photogeology or geo photography; a technique first structured by the united states in late 19th century and later incorporated in united state geological survey. the weekly modules will demonstrate the concept and principles of photogeology and its applications in real life. Lecture 7: photogrammetry and its significance; loading please wait, while we are loading the content aerospace engineering agriculture architecture. Pointing devices include handwheels, footdisk, mouse, trackball, cursor. a typical configuration consists of a special cursor with an additional button to simulate z movement (see fig. 6.6). handwheels and footdisk are usually offered as an option to provide the familiar environment of a stereoplotter. A ground coordinate system (or sometimes is called object space) is usually defined as a 3d coordinate system that utilizes a known geographic map projection. ground coordinates (x, y, z) are usually expressed in feet or meters. the z value is elevation above mean sea level for a given vertical datum. interior orientation.

Lecture – 07 photogrammetry and its significance hello everybody welcome back. so, when previous lectures we talked about the brief introduction of remote sensing, importance of photo geology and some part of photogrammetry also. but we would like to have a little more information on the. Photogrammetry uses the basic principle of triangulation, whereby intersecting lines in space are used to compute the location of a point in all three dimensions. to triangulate a set of points one must also know the camera position and aiming angles (together called the orientation) for all the pictures in the set.
