AbstractWith the advent of modern electronic distance measuring equipment, the possibility of carrying out long precise traverses economically has now become a reality and, at present, many remote areas, hitherto unsurveyed, are being controlled by this means. Recent accounts have described traversing by Tellurometer in Australia and Kenya where, because of the nature of the terrain, traverses have been run along existing roads, using towers in order to obtain a reasonable length of line in flat bush country. When one considers the amount of flat bush-covered and forested conntry in various parts of the world, the scope for this type of control would there is in various parts of the world, the scope for this type of control would seem to be very great indeed. It offers a means of providing accurate control quickly and cheaply, following on the opening up of an area by the first roads.
