As a rule, vertical aerial photographs are easier to interpret than oblique photographs because of the standardised ways in which they are taken - with set scales and at a single non-arbitrary angle (10).

Air photos record all visible features on the earth's surface from an overhead perspective. Although the features are visible, they are not always easily identifiable. The process of studying and gathering the information required to identify the various cultural and natural features is called photo interpretation.
Evaluating aerial images characteristics of aerial imagery that relate to the presence/absence of wetland hydrology are collectively referred to as “signatures” and those signatures that are correlated to the presence of wetland hydrology are generally referred to as “wetland signatures.

Another useful tool in interpreting aerial photographs is the ability to view photos stereoscopically. Stereo viewing is very similar to the way you perceive things in terms of depth or the distance to objects. For nearby objects, you can tell if something is close or farther away.
Aerial photographs are an invaluable source of information for the study of the nature and characteristics of the coastal and terrestrial environment.
Aerial and satellite images, known as remotely sensed images, permit accurate mapping of land cover and make landscape features understandable on regional, continental, and even global scales. Transient phenomena, such as seasonal vegetation vigor and contaminant discharges, can be studied by comparing images acquired at different times.
The term aerial photography refers to taking photographs from an elevated position, often using an airborne craft, including such equipment as rockets, airplanes, hot air balloons, and more recently, drones. To be considered an aerial photograph, you have to take the image with equipment that is not based on the ground.
To meaningfully interpret aerial photographic imagery, simultaneously consider both the age and quality of available imagery.
Archaeology has long benefited from the use of aerial photography, revealing sites that are often difficult or even impossible, to see on the ground.
For the mapping of terrestrial features, aerial photographs usually are taken in accessible with the use of satellite technology and expert interpretation.
In the previously mentioned manual of photographic interpretation,[1] the author attempts, with the aid of aerial photo examples, to demonstrate that these three.
Knowledge of map features, map symbology, and principles of interpretation is needed. • aerial photographs are used to construct topographic maps and to keep the map information up-to-date. The best conditions for evaluating and interpreting terrain will be obtained if the interpreter has both a good topographic map and recent aerial photographs.

Shape refers to the general form, configuration or outline of individual objects and is normally the first thing the eye sees in an aerial photograph. In many cases it provides immediate identification, however many objects have a similar shape. A circular object could be a gas holder, a chimney, a well or a roundabout, depending on its size.

Landslide inventory maps are commonly prepared through the visual interpretation of stereoscopic aerial photographs and field checks. Stereoscopic satellite images can also be interpreted visually.
Principles and techniques of extracting descriptive and metric information about the environment.
Color-infrared (cir) aerial photography--often called false color photography because it renders the scene in colors not normally seen by the human eye--is widely used for interpretation of natural resources. Atmospheric haze does not interfere with the acquisition of the image.

Description: aerial photographic interpretation is the process of examining objects on aerial photographs and determining their significance.
Photogrammetry (also called metric photogrammetry) is concerned with obtaining exceptionally precise quantitative measurements from aerial photographs, whereas photographic interpretation (or interpretive photogrammetry) focuses more on the recognition, identification, and significance of features on photographs (wolf and dewitt 2000, paine and kiser 2003).
