- Direct method of contouring is
- The correction applied to the measured base of length ‘L’ is
- The shortest distance between two places measured along the surface of the earth, is
- Longitude of a place is the angular distance between the meridian of the place and
- If the altitudes of a star at its upper and lower transits are 60° 30' and 19° 30' respectively, the latitude of the place, is
- The altitudes of a circumpolar star at culminations are 70° and 10°, both culminations being north of zenith. The latitude of the place, is
- Triangulation surveys are carried out for locating
- For plane ground the scale of a vertical photograph will be same as that of a tiled photograph along the photo parallel through
- If the general ground level of any area is 10% of the flying height, the principal points may be used as the centers of radial directions for small scale mapping even in tilted photograph up to
