Conducting geodetic monitoring. Monitoring of displacements and deformations of the Earth's surface and buildings. Price

Land displacement monitoring (InSAR Ground Deformation Monitoring) is carried out through the implementation of interferometric processing of multi-pass radar images of the same area, acquired with the same technical parameters and imaging geometry.

Radar interferometry allows for the detection of surface displacement and objects located on it with centimeter-level accuracy (for the Earth's surface) and millimeter-level accuracy (for buildings and structures), using spaceborne radar images as input data.

Geodetic monitoring aims to detect deformational changes, determine the causes of their occurrence, and provide forecasts for their future development and changes.

The Purpose of Land displacement monitoring (InSAR Ground Deformation Monitoring)

To detect and assess ground displacements above areas of underground mining, map the deformation of quarry walls and benches, or identify deformations of structures, expensive GPS monitoring is not necessary. Radar interferometry allows achieving millimeter-accuracy measurements over large areas, comparable to the precision of GPS monitoring, without the need for costly field infrastructure.

Radar interferometry is indispensable for:

Timely detection of ground displacements above areas of underground mining;
Mapping deformations of quarry walls and benches;
Monitoring natural and man-made displacements and deformations of buildings and structures;
Monitoring critical industrial facilities, pipelines, roads, railways, and other objects.

FAQ

Difference between Land displacement monitoring (InSAR Ground Deformation Monitoring) and space monitoring?

Seismic monitoring provides information that is a short-term precursor to the oncoming deformation of rocks at local sites. Space monitoring provides information in the long term about the processes occurring both in local observation sites and over a large area. Thus, these methods do not exclude, but complement each other.

What are the advantages of interferometry over GLONASS/GPS/NavlC/BeiDou/Galileo monitoring and ground leveling?

The main advantage is that space monitoring can cover large areas. At medium and large fields, there are long geodetic lines with thousands of reference points. As a rule, they are surveyed once or twice a year at each point where a reference is laid. Thus, information on displacements is available at intervals of once a year or once in a week. During this time, deformation may develop outside of the Customer's control. Space radar monitoring allows the site to be evaluated on a monthly basis.

What is the essence of the radar interferometry method?

The main data extracted from a radar survey are amplitude and phase. Repeated radar survey allows to determine phase differences caused, for example, by shifts of the earth's surface. Such shifts can be identified when processing radar survey data in specialized software products using various methods. The principal advantage of radar interferometry over other methods of monitoring vertical and lateral deformations is the direct measurement of differences in relief that occurred between two (three, five) surveys. The resulting interferometric displacement file usually shows an integral picture of displacements.

With the use of satellite radar interferometry is it possible to prevent catastrophically rapid subsidence of large areas of technogenically loaded territories, for example, settlements near underground mining sites?

On the present day, there is no method that can guarantee the prediction of ground surface collapse. There are criteria for the occurrence of such catastrophes, some of which (such as ground surface displacement rate, its spatial gradient, displacement acceleration) can be assessed using data from spaceborne radar imaging. In combination with other methods (repeated leveling, satellite geodesy, seismic monitoring), radar imaging allows for obtaining comprehensive and systematic information about ground surface displacements, evaluating the mentioned criteria, and spatially identifying hazardous areas.

What changes has space radar sensing undergone in recent years?

The number of satellites, the quality and variety of the data received are increasing, the technical characteristics of imaging systems and methods of processing the data received are being improved, and new software for processing data from remote sensing radar satellites is constantly being updated and developed.

Geodetic monitoring

Geodetic monitoring is a system of permanent and/or continuous observations, analysis and forecasting of the current geodynamic state of the geological environment, carried out within the specified regulations within the considered natural-technical system.

When is geodetic monitoring needed?

Geodetic monitoring is required in the following cases:

During the construction, reconstruction, and restoration of buildings and structures;
When using industrial, hydro, or energy technical facilities;
When intervening in the geological or hydrological conditions of a site.

Geodetic monitoring is conducted during the construction of new structures or the restoration of existing ones to monitor settlement, deformation, and tilt. Permissible limits for these parameters are specified in construction codes, standards, regulations, and building rules. These limits should not be exceeded. The goal of geodetic monitoring is to track these values and prevent their exceedance.

Geodetic monitoring is performed throughout the year following the completion of construction or reconstruction works. During the observations, the following processes are monitored:

Settlement - vertical displacement;
Shifts - horizontal displacement;
Tilts - deviations from the vertical.

This helps to prevent deformations, collapses, and other adverse events. If the changes do not stabilize, monitoring is extended and continued beyond the initial year.

How often should geodetic monitoring of building deformations be performed?

The frequency depends on the construction and erection cycles. After completion of construction works on the site, monitoring is usually carried out until the settlement stabilizes. Geodetic monitoring cycles are usually conducted once per calendar month, in case of intensive growth of settlement the frequency of cycles can be increased up to 3 times per month (and more).

Purpose of geodetic monitoring

The purpose of geodetic monitoring is to obtain data on critical deviations of buildings and structures from those specified in the project, with the determination of the time interval of occurrence of these changes. Geodetic monitoring of buildings is a periodic check for deformations, which is carried out by geodetic methods, through inspection and calculations, during the construction of buildings and structures.

Objectives of geodynamic monitoring

Regular monitoring of the current natural and man-made geodynamic state of the subsurface within the territory of deposits using modern high-tech equipment and efficient measurement techniques.
Identification of patterns of occurrence and spatial-temporal development of various manifestations of natural and man-made subsurface geodynamics, including establishing the nature and mechanism of relationships between these manifestations and spatial-temporal changes in the parameters of deposit development. Conduct and systematically update the geodynamic zoning of the deposit territory (with necessary revisions as new geodynamic information is obtained), identifying potential areas of increased geodynamic risk within the deposit territory.
Providing recommendations for optimizing the prospective placement of systems and facilities on the deposit territory to avoid potential emergency situations related to geodynamic factors.
Systematically compile information and annual comprehensive reports with necessary attachments, recommendations, and programs for subsequent monitoring cycles.

Methods of remote sensing of the deposit territory from space (InSAR) allow for:

Quantitative assessment of the degree of modern activity of faults within the developed hydrocarbon deposit territory and adjacent areas, as well as the temporal changes in fault activity.
Monitoring possible ground subsidence associated with deposit development (fluid extraction, reservoir pressure depletion) in the early stages of their development.
Detection of local variations in gravity reflecting deformation processes and fluid dynamics within the geological environment occurring in the geological intervals, including potential compaction of reservoir rocks due to hydrocarbon extraction, temporal changes in reservoir pressure, and fluid withdrawal/injection balance.
Identification of local areas with anomalous deformation processes and estimation of parameters of sources of local anomalous movements.
Development of possible prognostic signs of hazardous geodynamic processes.
Prediction of areas with increased geodynamic risk within the deposit territory.

What is InSAR (Interferometric Synthetic Aperture Radar) Ground Deformation Monitoring, and how does it contribute to land displacement monitoring?

InSAR Ground Deformation Monitoring is a technique that uses radar images from satellites to measure ground displacement over time. It contributes to land displacement monitoring by providing precise and detailed information on surface movements, including subsidence, uplift, and other deformations.

How does the InSAR process work, and what are the key steps involved in generating ground deformation maps?

The InSAR process involves comparing radar images acquired at different times to detect changes in the phase of the radar signal. Key steps include data acquisition, image processing, interferogram generation, and phase unwrapping. These steps result in ground deformation maps that display changes in elevation.

What are the main applications of InSAR Ground Deformation Monitoring, and how does it benefit various sectors such as geosciences, infrastructure monitoring, and environmental management?

InSAR has diverse applications, including monitoring natural processes such as volcanic activity, landslides, and tectonic movements. It also aids in infrastructure monitoring, detecting subsidence in urban areas, and supporting environmental management by assessing the impact of ground deformations on ecosystems.

How does InSAR technology address challenges related to traditional methods of land displacement monitoring, and what advantages does it offer in terms of accuracy and efficiency?

InSAR technology addresses challenges by providing a wide-area coverage and high precision without the need for direct physical contact with the ground. Unlike traditional methods, it offers continuous monitoring, high accuracy, and the ability to detect small-scale deformations over large areas, enhancing efficiency in land displacement monitoring.

In what ways does InSAR contribute to early warning systems for potential hazards, and how can it assist in risk mitigation strategies?

InSAR contributes to early warning systems by detecting ground deformations that may precede natural hazards such as landslides or volcanic eruptions. This early detection enables timely warnings, allowing for the implementation of risk mitigation strategies, evacuation plans, and the protection of infrastructure and communities in vulnerable areas.
