A photograph was taken from an altitude of 1700.0 m. above datum. If the average elevation of the project area is 250.0 m above datum, and the focal length of the camera is 208.90 mm.,

  1. What is the ground coverage if the format of the photograph is 23.0 cm x 23.0 cm?
  2. If the percentage end lap is 65%, what is the ground area (in sq. meters) of the end lap?
  3. What was the air base?
  4. If the aircraft flew and at a speed of 250 km/hr, what was the intervalometer setting?

Solutions

Expert Solution

This is problem based on photogrametry.

Air Base: The air base of a point is the total movements of a image of that point in a focal plane between two successive exposure.

As a body is projected to a high altitude above the earths surface, the variation of the acceleration of gravity with respect to altitude y must be taken into account. Neglecting air resistance, this acceleration is determined from the formula a=?g0[R2/(R+y)2], where g0 = 9.81 m/s2 is the constant gravitational acceleration at sea level, R = 6356 km is the radius of the earth, and the positive direction is measured upward. Part A With what velocity does the particle strike...

A satellite is launched into an orbit at an altitude 200 km above the surface. Onboard is an exquisitely sensitive atomic clock that is synchronized with an identical clock on Earth. After orbiting for one year, the satellite is captured, returned to Earth, and the clocks compared. What will be the shift in time between the two clocks?
