Despite the advent of spectacular satellite images, aerial photography remains an important component of remote sensing. The application of aerial photography in the visible and near-infrared range of the electromagnetic spectrum generally relates to situations where high-resolution information is required. The resolution varies but is normally in the region of 0.5-1 m, which allows small individual targets to be identified. Aerial Photograph Collections can be viewed at: Suffolk
from the Air, U.K. Generally aerial photography is not useful in meteorological applications such as weather forecasting where an image covering a large area is required. However, it is applicable in monitoring the effects of severe weather such as flooding. This type of event may occur rapidly without warning but aerial surveying can be instigated equally as rapidly. View images of the 2002 and European Floods at CBC News, Canada, BBC News, U.K. and The Guardian, U.K. The fine detail displayed on aerial photographs makes them useful in a number of disciplines. Geologists use them for distinguishing different rock types. Although different rock types are difficult to distinguish on black and white photographs they are associated with different tones, drainage networks and types and density of vegetation, all of which may be observed on large-scale photographs.
