Answer 1

Explanation:

In the mid-19th century the Survey of India organized a systematic program to measure correctly the heights of the Himalayan peaks. The Nepal and Uttarakhand peaks were observed and mapped between 1849 and 1855. Nanga Parbat, as well as the peaks of the Karakoram Range to the north, were surveyed between 1855 and 1859.
