Photographic interpretation is “the act of examining photographic for the purpose of identifying objects and judging their significance” (Colwell, 1997). This mainly refers to its usage in military aerial survey using photographs taken from aircraft and satellites. The principles of image interpretation have been developed empirically for more than 150 years. The most basic are the elements of image interpretation: location, size, shape, shadow, tone/color, texture, pattern, height/depth and site/situation/association. They are routinely used when interpreting aerial photos and analyzing photo-like images. An experienced image interpreter uses many of these elements intuitively. However, a beginner may not only have to consciously evaluate an unknown object according to these elements, but also analyze each element's significance in relation to the image's other objects and phenomena.
