Aerial photography is to be taken of a tract of land that is 8 x 8 mi2. Flying height will be 6000 ft above terrain, and the camera has a focal length of 6 inches. If the focal plane opening is 9 x 9 inches, and minimum side overlap is 40%, how many flight lines will be needed to cover the tract for the given data?
a project requires counting the number of people on a beach by using aerial photography. Assuming a 2-ft-diameter circle as a reasonable size for a person when viewed from above, and assuming a film with 80 line pairs per millimeters resolution will be used, what photo scale will be required? If a 152-mm-focal-length camera will be used, what is the required flying height above the beach?
Aerial photographs at a scale of 1:6000 are required to cover an area of 6 x 6 mi2. The camera has a focal length of 6 inches and focal plane dimensions of 9 x 9 inches. If end overlap is 60% and side overlap is 30%, how many photos will be required to cover the area for the given data?
An aerial camera has a 9½-inch square film format and a 6-inch focal length lens. What must the flying height (in meter) be to obtain a scale of 1/2000? (Hint: 1 inch=2.54 cm)
Q1.) An aerial camera has a 9½-inch square film format and a 6-inch focal length lens. What must the flying height (in meter) be to obtain a scale of 1/2000?

2. What is the height above sea level at which an aircraft must fly in order to procure photography at an average scale of 1:12 000, if the average elevation of the area is 3000 m and the camera to be used has a focal length of 153 mm?
2 What is the height above sea level at which an aircraft must fly in order to procure photography at an average scale of 1:12 000, if the average elevation of the area is 3000 m and the camera to be used has a focal length of 153 mm? The length of a section line (1 mile) lying at an elevation of about 300 m scales 10.16 cm on a photo. The focal length of the carnera used is 153.26...

A housing development is being planned for a tract of land near the river. To prevent flood damage to the new homes that will be built on this low-laying land, an earthen embankment can be constructed. The height of the embankment will be determined by an economic analysis of the cost and benefits. The embankment can be expected to last 50 years and will require no maintenance. Whenever the flood water flows over...
