A camera at a 2000 m altitude captures a 60 m high building. If the image of the building displays a relief displacement of 30 mm, determine the flying height using the displacement formula.
💡 Hint: Start solving through the formula.
In a photography survey, the flying height can be shifted. If at 1800 m we have three terrain heights measured as 200 m, 500 m, and 350 m, determine the maximum visible scale using the plane's performance ratio.
💡 Hint: Remember how focusing on the tallest structure can affect the scale calculations.
