Ground Based Aerial Photography

Areal photographs can be obtained in many different ways.

An airplane (e.g. the Cessna 172) can be used for heights between 500 feet (above sea) and 10.000 feet.

A Helicopter, ( HAP) especially for heights below 500 feet.

A remotely controlled helicopter ( RCAP) for heights up to 300 feet.

A blimp (or balloon, or zeppelin) ( BAP) for heights up to 500 feet.

A kite ( KAP ) (not recommended for professional use).

And finally, a rising trend, a Mast ( GBAP ) for heights up to 100 feet.
