Surveyors of History

As a surveyor myself, I am always interested in who did my job in the past, in other lands, etc. To map their travels, explorers needed to know the exact location of their starting point. In 1825 William Moorcroft went missing after five years in the Himalayas, though there is conjecture in his achievements, this was the launch pad that led to surveying India. They began with Great Trigonometrical Survey of India, with the measurement of the sub continent along with the 78th meridian, northward from the tip of India, this resulted in the first accurate height of the Himalayas.
