Survey of route between Yangi Hissar and Yarkand via Sarikol (1892)
This map can be found in an appendix to the second volume of Труды тибетской экспедиции 1889-1890 гг. подъ начальствомъ М. В. Певцова [Works of the Tibetan expeditions 1889–1890 under the leadership of M. V. Pevtsov] edited by M. V. Pevtsov and published by the Russian Geographical Society in 1892.
It is a route survey based on data gathered by the geologist and mining engineer K.I. Bogdanovich. The survey covers an area between Yarkand in the east, Yangi Hissar in the north and Sarikol (today Tashkurgan) in the west. Rivers and altitudes are sketched out giving an idea of the surrounding geographical features.
Seven other maps are appended to this volume: one large-scale overview of Eastern Turkestan and four additional small-scaled route surveys of areas to the south and west of the Takla Makan Desert, as well as two sketch-maps of areas with gold mines.
