Find the length of a road if the ground coordinates at its beginning are ( 1000m, 2000m) and the coordinates at the end point measured on an aerial photo are ( 105 mm, 133 mm). knowing that the focal length of the applied camera is 14 cm, the flight height over the end point of the road in meters is equal to "2004" and the end point of the road lies at the same level of the sea.

1. Sometimes in leveling across topographic features such as rivers, it is difficult or may be utilized at such impossible to keep back sights and foresights short and equal. locations. 2. The most common method of determining difference in elevation, in this method a telescope with suitable magnification is used to read graduated rods held on fixed points. A horizontal line of sight within the telescope is established by means of a level vial or automatic compensator. 3. It is a leveling that consists in making rod readings on the upper, middle and lower crosshairs. 4. This leveling is useful in investigating and selecting the most economical grade, location, and depth for sewers, pipelines, tunnels, irrigation ditches, and other projects. 5. leveling is used where difficult terrain, such as mountainous areas, precludes the use of conventional differential leveling.
