Rick
Engineering Company provided topographic mapping
at a scale of 1"=40' with a two-foot contour interval was
required for this 2500 acre project. Over 70 control points
would have been required to control this photography using
conventional field based methods. Additionally, access
to much of the property was restricted due to access issues
as well as inaccessible terrain. It was determined that
airborne GPS methods could be used while still maintaining
necessary control accuracy requirements. Eight ground control
points were paneled. Two ground control stations were monitored
during the flight. I K. Curtis Services flew over 100 models
with their RC 30 camera coupled with a Novatel GPS receiver.
Crossed strips were flown across the North and South and
its of this rectangular block in order to provide the necessary
photo ties for the adjustment. The photo above shows the
flight patterns superimposed upon a digital ortho photo.
Mapping was completed under an aggressive timeline.
