Appendix

to the Order of the acting minister of digital development, innovations and the aerospace industry of the Republic of Kazakhstan of January 11, 2024 No. 13/Tax Code

The instruction for geodetic works on geodynamic grounds

Chapter 1. General provisions

1. This Instruction for geodetic works on geodynamic grounds (further - the Instruction) is developed according to subitem 213-25) of Item 15 of the Regulations on the Ministry of the digital development, innovations and the aerospace industry of the Republic of Kazakhstan approved by the order of the Government of the Republic of Kazakhstan of July 12, 2019 No. 501 (further - the Provision of the Ministry).

2. This Instruction is intended for practice guidance under the organization and accomplishment of geodetic works on geodynamic grounds.

3. In this Instruction the following basic concepts are used:

1) the geodynamic ground (further - the ODS) - the territory in which geodetic, astronomical, gravimetric and geophysical observations, data which are used for determination of movement of Items of the land surface are carried out;

2) high-precision geodetic network (further - VGS) - satellite geodetic network with average distance between adjacent geodetic Items of 150-300 kilometers which spatial coordinates are determined concerning Items of fundamental astronomo-geodetic network;

3) the global navigation satellite systems (further - GNSS) - the space systems intended for determination of coordinate and time parameters (geographical coordinates and heights, speed and the direction of movement, time) land, water and air objects;

4) the state gravimetric network (further - GGRS) - the gravimetric networks used for the purpose of establishment and (or) distribution of unified gravimetric basis;

5) fundamental astronomo-geodetic network (further - FAGS) - satellite geodetic network with average distance between adjacent geodetic Items of 650-1000 kilometers which coordinates are determined in geocentric spatial system of coordinates.

4. Geodetic works on the ODS is part of complex of the scientific geodetic and geophysical surveys directed to receipt of quantity characteristics of stability of mutual provision of points of the land surface in time which measurements are carried out by several consecutive cycles, issues of high-precision measurements are also resolved, following the results of in each cycle observations which allow to determine the size of possible systematic and random errors of results of measurements are carried out.

5. The types of geodetic works which are carried out on the ODS:

1) organization and planning of project works;

2) leveling;

3) satellite measurements;

4) gravimetric measurements;

5) processing of results of measurements.

Chapter 2. Organization and planning of project works

6. The engineering design of geodetic works on the ODS is constituted based on geophysical surveys on this ground.

7. The engineering design for geodetic works on the ODS is constituted on the basis of the specification and developed taking into account the existing geodetic networks, geological features of the ground revealed on the basis of geophysical, geological and geomorphological surveys. Basis of the engineering design is results of the field reconnaissance which is carried out with participation of the geologist in the cities of the representative of the chief architect of the city, and also the representative of research institution or organization responsible for works on the ground.

8. Before creation of the engineering design the following materials gather:

1) the specification from territorial is scientific - research institute or the organization, containing the characteristic of geological structure and the tectonic phenomena near the projectible ground, complex of the planned geophysical observations (gravimetric, seismic) and solvable tasks, the scheduled plan of the main stages of researches and the scheme of Items of geophysical observations;

2) results of all geodetic works with characteristics of their quality and method of fixing of Items which are earlier performed near the ground;

3) materials of the analysis of all types of the observations allowing to reveal nature and size of possible deformations of the land surface near the ground and their connection with tectonic processes;

4) results of field inspection of safety of the existing geodetic networks and geomorphological conditions.

9. Materials of geodetic measurements and their processing on each cycle of observations are drawn up in report type, constituted according to requirements of third and chapter 4 of this Instruction.

Chapter 3. Leveling

10. Leveling on the ODS is carried out according to requirements of this Instruction and the Instruction for leveling approved by the order of the Minister of digital development, innovations and the aerospace industry of the Republic of Kazakhstan of March 16, 2023 No. 94/Tax Code (it is registered in the Register of state registration of regulatory legal acts for No. 32090) (further - the Instruction for leveling).

11. For studying of vertical earth movements the method of repeated leveling is used. In case of accomplishment of repeated leveling the speed of vertical movements is determined.

12. In case of accomplishment of repeated leveling of the route of the courses, design of transitional points, installation sites of the tool and transitional points in each cycle of measurement shall match the previous indicators.
