Problem: photogrammetry
Type A: If it takes 650 vertical photographs at a scale of 1:22,000 to completely cover a square-shaped study area, how many photographs would be required to cover the same area at a scale of 1:65,000?
Type B: A mapping camera has a focal length of 152mm. To obtain vertical airphotos at a scale of 1:40,000, the camera would have to be flown at an altitude of how many meters?
Type C: Suppose you wish to fly a photographic mission with a 350mm focal-length lens over a study area with an average elevation of 1,500m. If the airplane has a maximum operating ceiling of 13,700m above sea level, could vertical airphotos be obtained at a scale of 1:40,000?
