In image interpretation activities, there are some elements that are used as guidelines in the detection, identification to identify an object. These elements when arranged in a hierarchy according to the level of difficulty of interpretation will look like in the picture below:

Image interpretation is an activity of assessing, reviewing, identifying and recognizing objects in images, then assess the significance of the object. In image interpretation, there are two main activities, namely object recognition and utilization of information. The steps are usually done to acquire remote sensing data is detect and analyze objects in the images to be useful for a variety of images.
Object recognition is an important part of image interpretation. The principle of object recognition in images based on the investigation of the characteristics of the objects contained in the image. Various characteristics to recognize objects in images is called image interpretation elements, as follows:
Hue and color
Rona is the degree of darkness or brightness levels in the image of the object, while the color of the form is visible to the eye by using a narrow spectrum, narrower than the visible spectrum.

form                 Is a qualitative variable that provides the framework configuration or an object. We can be the object of a football stadium on the aerial photo of the rectangular shape. so we can recognize the shape of the volcano are convex. Schoolgirl shaped I, L, U, or box. Size Size is an object which, among other characteristics such as distance, area, slope height and volume. Size of the object in the image such as scale, therefore the use of size as image interpretation, should always keep in mind the scale .. Sample: Field sports football is characterized by the shape (rectangular) and a fixed size, which is about (80 m - 100 m). Texture is the frequency change of hue in the image. There are also those who say that the texture is repetition in hue group of objects that are too small to be distinguished individually. Texture is given by: coarse, fine, and medium. For example: Forests coarse textured, medium textured shrubs and bushes finely textured. Pattern Pattern or spatial arrangement is a characteristic that marks the many objects and human formation for some natural objects. Example: The pattern of the flow of the river marks the geological structure. Trelis flow patterns mark structural folds. Transmigration settlements identified with a regular pattern, the size of the home and away uniforms, and always facing the street. Rubber, palm oil, coffee plantations are easily distinguished from the forest or other vegetation with a regular pattern, namely the cropping pattern and spacing. Shadow Shadow detail is hidden or objects are in the dark. Nonetheless, the shadows can also be an introduction to the key importance to some objects precisely with the shadows become clearer. Example: steep slopes are more obvious in the presence of shadows, as well as chimneys and towers, appear more clearly in the presence of shadows. The site was the location of an object on other objects in the vicinity. For example, settlements are generally elongated in the coastal shelf edge, or natural levee along the way. Also rice, are common in the lowlands, and so on. Association Association is a relationship between objects with one object lainnya.Contoh: Train station in association with the railroad of more than one (branching), the airport associated with an airport.
