It was modified to minimize the manual effort in the flight
planning process. The modified version of the computer program addressed
some specific aspects of aerial photogrammetry for surveying
applications in civil engineering, for example, overlapping of photo imagery
to guarantee the appropriate overlapping coverage. All that is left
for a pilot is to select the region of interest (survey area) on an interactivemap,
camera model, photo size and resolution, flight altitude above
ground, flight speed, and the longitudinal and traversal coverage area of
each photo (see Fig. 4).
