Commemorates the Centenary of the Royal Thai Survey Department (1985).   Modern map surveying in Thailand began in the reign of King Chulalongkorn in 1875.  The Map Survey Division was established to build the roads in Bangkok and lay out the map for the telegraph linking Bangkok to Phra Tabong (Battambong) and also to map around the Thai Gulf.  He also ordered the establishment of Thai cartography school in 1882, which later became the Royal Thai Survey Department in 1885.
