Abstract

Photography is one of the main means of transmission of information and collection of geographic data with wide applications, and aerial photography and remote sensing are the most common ways of quick access to geographic information remotely.
- Better understanding of land by viewing and interpreting aerial and space images;
- Identification of natural and artificial phenomena and features and their geometric measurement;
- Introduction of geographic factors of the formation, development and expansion of cities;
- and the production of aerial photos and their conversion into topographic and thematic maps are among the applications of aerial photography in the earth sciences, especially surveying and geography. Aerial photography is the most economical way to access geographic information remotely. Aerial photography, due to its many advantages, is one of the most efficient methods of collecting geographic information that has certain advantages compared to terrestrial observations (terrestrial surveying). The most important of such features are addressed here.
