Solution

The survey of India was started over hundred years ago. First, our country is mapped on scales of 1, 2, 4 miles to the inch. But most important are 1: 1,000,000 scale maps. In the year 1909, the International Map Committee in London published 1/M sheets or one-in-million maps. Besides, some are published on 1: 2,000,000 or 2M scale by reducing one-in million maps to half the scale.
