The Himalayan mountain kingdom of Bhutan is poorly
mapped and smaller scale coverage from adjacent countries
and world series offers the most useful available coverage.
Official mapping is carried out by the Survey Department
(SB) in the Department of Trade and Industries, which has
inherited mapping systems from Survey of India. A 1:50,000
scale series is in progress, and sheet lines follow the Indian
hierarchical sheet division practice. This six-color map is
on a polyconic projection, Everest ellipsoid, and shows relief
with 40 m contours. It covers the country in 78 sheets, but
only the maps around the capital Thimpu have so far been
published. SB has also recently
published small scale administrative and physical maps of
Soviet military topographic mapping of Bhutan exists at the following scales: 1:1,000,000 (4 sheets, complete coverage, published in 1973);
1:500,000 (4 sheets, complete coverage, published 1970-1987); 1:200,000 (13 sheets, complete coverage, published 1977-1989) and 1:100,000 (22 sheets,
partial country coverage, published 1985-1986). These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
