A Survey Department, inaugurated about 1887, has completed the general survey of the whole country, and has made a cadastral survey of a large part of the thickly inhabited and highly cultivated districts of central Siam.
A cadastral survey seems also to have been instituted, and one of the documents relating to it states that a certain Uru-Malik, whose name appears to indicate his Canaanitish origin, was governor of the land of the Amorites, as Syria and Palestine were called by the Babylonians.
Finally, in 1854, a cadastral survey of the whole of the United Kingdom, only excepting uncultivated districts, was resolved upon, on a scale of 1: 2500, still larger scales (1: 500 or 1: 1000) being adopted for town plans.
The maps are based upon the cadastral plans (1: 1000), thoroughly revised and connected with the triangulation of France and furnished with contours at intervals of 5 m.
The Specialkarte of Austria-Hungary on a scale of r:75,000 (765 sheets), based upon a triangulation and cadastral surveys (1816-1867), was completed in 1889, and published in heliogravure.
