Photo Interpretation

Photo interpreters can read an aerial photograph like a book, and they employ many skills to help them analyze the terrain they are viewing.

Photomosaics

One method that aerial photo interpreters use to view large regions in one glance is called mosaicking. Several photos of adjacent areas are pieced together like a jigsaw puzzle to present the "big picture".

Stereo Photography

The Earth in Stereo

Natural and man-made features can be seen in three dimensions with the aid of a stereoscope and two overlapping scenes. With the addition of depth, aerial photos can provide the interpreter with more information on geologic boundaries, terrain characteristics, relative heights, and regional topography.

Anaglyphs

If you have a pair of red/blue glasses you can simulate the 3-D effect of using a stereoscope by viewing these anaglyphs made from aerial photos.
