  • Second order high accuracy leveling network is consisted of permanently marked and accessible fundamental and temporary benchmarks. Fundamental benchmarks represent the points approximately evenly distributed on the entire territory of the Republic of Serbia at the average distance of not less than 20 km, or not more than 50 km, which the complete precise levelling network relies on. Temporary benchmarks can be main and supporting. They represent the points distributed at the distance less than 1.5 km in the form of levelling lines between the fundamental benchmarks.
