A-K's Plan of Lhasa was drawn by an Indian surveyor Kishen Singh, also called Krishna, or AK, who visited Lhasa in 1878-1879. The plan was part of A-K's report published in 1880. It was reproduced in Sarat Chandra Das' "Journey to Lhasa and Central Tibet" (1902) that served as a source for this digital reproduction. Mongolian Buddhist lamas, G. Ts. Tsybikoff [Tsybikov] and Ovshe (O. M.) Norzunoff [Norzunov] were familiar with the plan and mentioned it in their notes (available in this digital collection at: http://collections.lib.uwm.edu/u?/tibet,106 ) that accompany a set of 50 photographs of Lhasa taken in 1900-1901.
