Topographic and geodetic works

Zhanazhol Munai Service LLP provides a wide range of services in the field of topography and geodesy. Our personnel have various modern methods of carrying out topographic and geodetic works by means of high-precision equipment. It provides high quality field surveys and desk work stages.

The basis of topographic and geodetic surveys is engineering measurements of structures and communication lines of ground, underground and aboveground type available on the territory.

Together, engineering surveys help to make a topographic plan in digital and graphical form. 

Topographic and geodetic works with GNSS equipment of the Trimble R7 series

One of the indispensable devices for the project of topographic and geodetic works is a high-precision dual-frequency GNSS receiver.

• allows to abandon the use of theodolite and leveling moves;
• allows to carry out a planned high-altitude geodetic reference;
• using it, it is possible create a reference justification along the trace.

GNSS equipment helps to carry out breakdown, field tracing with high accuracy and in real time. Consequently, the process accelerates, the quality and productivity of work increases.

Deformation monitoring by digital levels

Monitoring and keeping track of deformations of objects (subsidence, roll, shifts) is an important task, especially in the process of construction and operation of structures and buildings.

To solve the problems of deformation monitoring, Zhanazhol Munai Service personnel use digital Trimble DINI 03 and Leica DNA 03 levels. They allow timely detection and prevention of the development of negative and dangerous natural and man-made processes.

It should be distinguished:

geodetic monitoring of subsidence of the foundations of buildings is carried out by means of precision levels

observations of shifts and roll are performed by high-precision robotic electronic total stations

The results obtained allow us to predict the scenarios of events: how the deformation will behave, and what specialized measures can prevent negative and dangerous consequences.

Geodesic equipment is equipped with built-in software that allows carrying out the removal in kind, as well as the breakdown of the main and mounting axes, elevations, slopes. 

Zhanazhol Munai Service LLP uses modern software products for the production of processing of topographic and geodetic surveys of total stations, levels, GNSS surveys, laser scanning, as well as for drawing up drawings, maps of various scales, 3D maps.

We work with programs: Trimble Business Centre, Surfer, CREDO, MapInfo, 3D FieldPro, AutoCAD, QGIS, GPSurvey, OpendTect, Trimble Geomatic Office.

List of topographic and geodetic services

• obtaining coordinates and heights of geodetic points, as well as materials on previously conducted surveys;
• creation of a geodetic reference network (geo-base) and/or survey justification on the studied area;
• search, detection and topographic and geodetic survey of engineering communications underground;
• engineering and geodetic surveys for design;
• preparation/updating of a topographic plan/geo-base.

Received materials and information are processed: data of geodetic and topographic studies are applied to maps. Further, accuracy of these data is determined through desk work.

Topographic and geodetic surveys are a mandatory stage of preliminary study of the territory, preceding geophysical exploration (gravity exploration, magnetic exploration, etc.). The information obtained as a result of topogeodesis is used to obtain accurate terrain data for the removal of survey points from the project in kind. Subsequently, these data will be used for secondary processing of geophysical surveys.

• collection, analysis of information about natural, man-made conditions of the area;
• reconnaissance, study of the features of the topography of the relief;
• creation of planned high—altitude geodetic networks - this allows you to determine the coordinates;
• topographic survey of the area at various scales;
• taking out research points in nature, as well as binding, obtaining their exact heights, coordinates;
• search and detection of underground and ground communications;
• creating a set of topographic plans with different scales (1:100, 1:200, 1:500, 1:1000 or any other);
• preparation of a technical report in paper and electronic form.
• technical report with information about the methodology, technology of the conducted research;
• rough sketches of fixed points of the reference geodetic network;
• catalog with coordinates and heights of survey points.
