English: This is the reduced copy of the first survey map of the Kumaon region, created by Captain W. J. Webb (the original map: File:1819 Map of Province of Kumaon by Webb.jpg). Published in the Historical Records of the Survey of India, Vol. III, 1856 by By Col. R. H. Phillimore

Title: Sketch of Kumoan, Captain W. J. Webb surveyor 1819

Notes: Reduced from preliminary map drawn by Robert Tate, assistant surveyor, scale 12 miles to an inch, shewing progress of Webb's survey 1815—9 ; unsurveyed areas in dotted lines.

Webb's triangles were based on latitudes observed at Kumaon and other stations, with no measured base-line [44–5]. The heights which he deduced for the snow peaks created a sensation amongst European geographers [46–8].

Webb's peak XIV is Nanda Devi, modern height 25,645 feet [p. 48 n.6]
