Q

How does flight altitude affect terrain interpretation? (4- 32-34)

A

High altitude - greater field of vision, reduced object size, reduced contrast

Low altitude - increased object size, increased contrast, reduced field of vision, ability to silhouette objects on skyline

Q

How does weather affect terrain interpretation? (4-38)

Q

How does season affect terrain interpretation? (4- 45-51)

A

Summer - reduced recognition of objects by contrast, increased cover due to foliage

Winter - improved contrast and recognition of terrain features (reduced foliage), often more cloudy (reduced ambient light), heavy snow may offer concealment of terrain/man-made objects
