What is Oblique Imagery?

Oblique imagery is aerial photography that is captured at approximately a 45 degree angle with the ground.  The angle which is inherent to oblique imagery allows viewers to see and measure not only the top of objects but the sides as well. Oblique Imagery more closely resembles how people normally view their landscape compared to traditional orthagonal (straight down) imagery.Click here for public access to the Johnson County oblique imagery.
