Aerial PhotoAerial Photo Aerial photography is captured with our two (2) company owned Cessna 206 turbo aircraft, which are configured specifically for aerial mapping. E-TOPO also maintains a complete black and white photo lab. Since 1988 we have continued to expand our in-house film library of stock low altitude aerial photography suitable for accurate two foot (2') contour mapping. The library photography is exposed only during optimum spring conditions of full defoliation and high sun angle.
The flying height above ground determines the nominal scale of the photograph.
In this example the blue represents a larger scale image and the red
a smaller scale.
