Množina: aerial photographies

Taking photographs from a high level (an aircraft or satellite). Aerial photography enables surface features to be detected, and is used by geologists, surveyors, engineers, meteorologists. In archeology, for example, aerial photography reveals surface features (such as crop marks, soil marks, shadow marks) that are not clearly visible from ground level and which indicate the presence of ancient features; crops will show differences in growth and color if they are growing over a buried wall foundation or other stone feature.
