The longitudes of two places at latitude 60° N are 93° E and 97° W. Their departure is

5100 nautical miles 5700 nautical miles 120 nautical miles 500 nautical miles

The distance between the minor control point and the principal point should be equal to

Base line of the left photograph of stereo pair Base line of the right photograph of stereo pair Sum of the base lines of stereo pair Mean of the base lines of the stereo pair

The meridian of a place is

A great circle passing through the place and the poles A great circle whose plane is perpendicular to the axis of rotation and it also passes through the place A semi-circle which passes through the place and is terminated at the poles An arc of the great circle which passes through the place and is perpendicular to the equator

The coverage is least if photography is

High oblique Low oblique Vertical None of these

Rotation of the camera at exposure about horizontal axis normal to the line of flight, is known as

Swing Tilt Tip None of these

Select the correct statement among the following.

A contour is not necessarily a closed curve. A contour represents a ridge line if the concave side of lower value con¬tour lies towards the higher value contour. Two contours of different elevations do not cross each other except in case of an overhanging cliff. All of the above statements are correct.

Select the correct statement.

Contour interval on any map is kept constant. Direct method of contouring is cheap¬er than indirect method. Inter-visibility of points on a contour map cannot be ascertained. Slope of a hill cannot be determined with the help of contours.
