The use of aerial photography to assess and map landscape change is a crucial element of ecosystem management.Aerial photographs are ideal for mapping small ecosystems and fine-scale landscape features, such as riparian areas or individual trees (Fensham and Fairfax 2002, Tuominen and Pekkarinen 2005), because they often possess a high level of spatial and radiometric (tonal) detail.

TRANSPORT AND COMMUNICATION Vertical photographs present approximately uniform scale throughout the photo but not oblique photos. The first images from space were taken on sub-orbital flights.The U.S-launched V-2 flight on October 24, 1946, took one image every 1.5 seconds. Landsat-7, for example, maintains 8-bit resolution for its bands and can therefore record values for each pixel that range from 0 to 255. Multispectral and hyperspectral sensors are those sensors that can resolve a multitude of wavelengths intervals within the spectrum. The scale of the photograph is inconsistent, i.e. They record exactly what a person would Remotely sensed satellite imagery is becoming increasingly common as satellites equipped with technologically advanced sensors are continually being sent into space by public agencies and private companies around the globe. from above. called horizontal photographs.

By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships. Example: It permanently preserves the existing ground conditions at a particular time. It describes the different types of photographs used, such as archival photographs and photographs taken by the researcher, and it focuses especially on photographs taken by participants.

SPACE DYNAMICS AND CLIMATOLOGY Digital photography has progressively increased the resolution of its cameras and images, but they're still based on single-unit pixels. The stereoscopic study is also more effective on vertical than on oblique photographs. history notes mathematics past papers Oblique photographs (also known as oblique aerial photographs or oblique air photographs) are taken from a high point, which is at an angle neither horizontal (ground level photograph) nor perpendicular (vertical aerial photograph) to the area being photographed. On the other hand, it is noteworthy from an examination of the previous . Temporal resolution is the amount of time between each image collection period and is determined by the repeat cycle of the satellites orbit. Vertical photographs present approximately uniform scale throughout the photo but not oblique photos. Videos are easier to be accepted by students. that is all objects found in the face of the camera are recorded even if they are not needed. A high oblique photograph features The spatial resolution of a satellite image, as described previously in the raster data model section (Section 4.1), is a direct representation of the ground coverage for each pixel shown in the image.
