Nikon India Private Limited Large Scale The concept of large scale in aerial photography refers to the images that usually cover smaller areas but in greater details. Greater details imply that, the objects and features of the ground appear larger and detailed in view. Whereas, the area that is covered by ground is smaller in scale. Small Scale The concept of small scale aerial photography however, is just the opposite of large scale. The smaller scale covers larger areas without much focusing on the details. The other features and objects of the ground are kept at a less focused and detailed size. The area that is covered by the ground is greater in small scale as compared to the large.
Fiducial Marks The Fiducial marks are small marks of registration that are exposed on the boundaries of an aerial image. The calibration of the camera measures the distance between each of the fiducial marks. A cartographer makes use of the information of the distance between each fiducial marks after the compilation of a topographic map. Stereoscopic Coverage The stereoscopic coverage refers to the three-dimensional view that takes place when the two images that are overlapping known as Stereo Pair is viewed with the help of a stereoscope. The interesting part of the stereo pair being the view of the same area in different photographs appearing different, which is later interpreted and combined as a 3-D view by the brain.
