Project mapping for dam construction purposes is to be produced at a scale of 1/2500, with a contour interval of 2.0 m.
A stereoplotter is to be used in which co-ordinates can be measured with a precision of 0.01 mm and parallax with a precision of 0.015 mm, and enlargement ratio, 4:1.
Assume (i) Mean terrain height = h = 250 m
(ii) Camera principal distance = 150 mm
(iii) ‘C’ Factor = 900.
a. Determine the flying height?
