Current analysis of geodetic security of the territory of the Dniester region of the Chernivets region. It is stated that until 1940 Bukovina was located near the warehouse of Romania, therefore all geodetic surveys that were located on its territory at that time were according to the normative documents of this region. After the establishment of the Chernivets region, the establishment of geodetic surveys began on its territory, first under the Regulations of 1939, and then under the Regulations of 1954–61. The current DGM was prompted by the Regulations of 1998, which in 2013 were replaced by the Procedure for the State Geodetic Survey. The number of DGM points (by class) that falls on the territory of the region is covered, as well as the average density of points per 1 km 2 . An assessment has been made of the feasibility of creating maps and plans for the territory of the Dniester region. A note has been issued about the need to thicken the DHM on the territory of the region.

As we have already noted, before the formation of Chernivtsi region, it was part of Romania. During this period, the 1st class triangulation was built in 1927–1962 by the Military Geographical Institute of Romania.

After the liberation of the Chernivtsi region, the state geodetic network on its territory and on the territory of the present Dniester district, in particular, was built in accordance with the Regulations of 1939, this is triangulation of II, III and IV classes in the Chernivtsi–Mogilev-Podilskyi–Rybnytsia area, laid in 1945. by units of the VTS, triangulation of classes II, III and IV in the Botoshany area, laid in 1944 by units of the VTS, triangulation of II, III and IV classes in the area of Northern Bukovyna, laid in 1941 by units of the VTS.

In 1954–61, new «Regulations on the construction of the state geodetic network of the USSR» were adopted. According to these Regulations, based on the existing network at that time, a new DGM was built on the territory of the present Dniester district. The following works were performed:

– 2nd and 3rd class triangulation, 3rd and 4th class optical and radio ranging polygonometry in the Chernivtsi - Yedintsi area , laid out in 1965 by parts of the VTS;
– 2nd, 3rd, 4th class triangulation, 3rd and 4th class light ranging and radio ranging polygonometry in the Khmelnytskyi – Vinnytsia – Kamianets-Podilskyi area , laid out in 1961 by the Parts of the VTS.

In 1998, the «Basic provisions for the creation of the State Geodetic Network of Ukraine» were adopted, which in 2013 were replaced by a new normative document «The Procedure for the Construction of the State Geodetic Network». According to these two normative documents, a modern DSM was created and modernized on the territory of the Dnistrovsky district.

Today, the total number of DGM points located on the territory of the Dnistrovskyi district is a total of 69 units of the corresponding class, of which:

– 1st class – 7 points;
– 2nd class – 13 points;
– 3rd grade – 29 points.

There are 20 units of 4th class points, which currently belong to digit geodetic networks.
