TRE ALTAMIRA has operated over 15 years in satellite RADAR data processing services, ranging from measuring ground motion over entire countries to identifying individual structure displacement.
Measuring surface deformation provides an understanding of ground response
to subsurface activity, both natural and anthropological.
We offer tailored services whatever your requirement. We provide ongoing monitoring (with or without installing artificial reflectors), historical analysis and support for data visualization, interpretation and integration. Satellites monitor wide-area surface motion as well as single structure displacement at regular intervals. They are useful in understanding the response to ground instabilities and active working, and provide data for the evaluation of risk models.
Monitoring provides regular and accurate updates of surface motion in near real-time
We are able to quickly process satellite images thanks to our advanced algorithms and computational power (CED), providing clients with updated deformation maps and displacement time-series.
According to the type of processing technique (SqueeSAR™, DInSAR, Rapid Motion Tracking or a combination) and monitoring needs, different deliveries can be guaranteed at different times: weekly, monthly, quarterly, yearly.
We task operational satellites to acquire images over your specific area of interest worldwide.
Optimizing your monitoring projects with artificial reflectors
Artificial reflectors (ARs) are ground-based artifacts that reflect radar signals back to the satellite at specific locations. There are two principle reasons for using artificial reflectors:
- to acquire displacement measurements over areas where the ground is not naturally reflective, such as areas covered by snow in winter months or densely vegetated areas
- to monitor specific locations within the area of interest
Proprietary single or double-geometry ARs
TRE ALTAMIRA has designed a lightweight single and double-geometry ARs for use in challenging environments. The reflector is lightweight, no subject to corrosion and designed to prevent the accumulation of dust, debris and snow.
From the design to the installation of the Artificial Reflectors, TRE ALTAMIRA is involved in all phases of the project. The layout of the ARs network is decided in close collaboration with the client, taking into consideration any specific requirements of the project. ARs are manufacured in house and their installation is conducted by our staff to guarantee the quality of measurements. Once the first few satellite images have been acquired, quality control checks are performed to ensure visibility and identify reflectors showing sub-optimal reflectivity.
ARs are only available for monitoring projects (see monitoring).
Archived satellite data are processed to measure retrospective surface motion
Synthetic Aperture Radar (SAR) satellites have been imaging the Earth since 1992. A large archive of SAR data already exists worldwide, containing information about historical surface displacement.
By simply providing us with your area of interest, we can determine what data archive is already available for a back analysis. This provides retrospective surface motion maps and time series of displacement to millimetre accuracy. Historical analyses are particularly encouraged to characterize the state of art of your area of interest and understand the effect of ground activities on pre-existing environment.
Satellite platform available for historical analysis:
The SqueeSAR™ Report is a detailed temporal analysis of surface motion using TRE ALTAMIRA’s industry leading SqueeSAR™ technique. Image stacks are processed quarterly, biannually or yearly, yielding a valuable deformation history for thousands of sample points per square kilometre. Results are prepared in spatial databases viewable in a GIS or on our visualisation platforms (TREmaps™, 3D VIEWER).
Executive Summary Reporting
TRE ALTAMIRA’s Executive Summary Report is a concise synopsis of the SqueeSAR™ Report. Deformation over critical assets or areas are summarized.
Fast Reporting Service
TRE ALTAMIRA’s Fast Reporting Service (FRS) provides deformation updates on a weekly, monthly or customized basis. Spatial information is presented as Interferograms, Deformation Maps and Rapid Motion Tracking (RMT) where high velocities are detected. A short synopsis on the data quality and motion observed is included.
TREmaps™, 3D VIEWER and WebGIS are web-platforms for data delivery and quick visualization of results.
Clients can take advantage of these solutions, rapidly visualizing millions of measurements points on an easy-to-use interface.
TREmaps™ uses a Google Maps interface. Clients can quickly and securely login to see their delivery packages. Beyond displacement maps and time-series data, they can also download project files and reports directly from the same portal. TRE ALTAMIRA has adopted systems and procedures that comply with industry standards to ensure maximum security and confidentiality of the projects.
TREmaps™ web application
3D VIEWER is a user-friendly application to visualize ground motion measurements in 3D over high resolution terrain models, particularly suitable for the mine environment.
WebGIS is a software service for storing, visualizing and analysing ground motion data from a web based graphical user interface. In order to facilitate the user’s access to data, their analysis, and to optimize the benefits of this source of information, WebGIS is an access point to query data, view results and download frames of interest, all from a dedicated and secure web platform.
TRE ALTAMIRA always offers full client support for the interpretation and integration of surface deformation data. We draw on the expertise of our highly trained staff with diverse backgrounds including geologists, geophysicists, environmental engineers and radar specialists.
Toolbar for ArcGIS
We have designed a toolbar for advanced analyses of our results in a GIS (geographical information system) environment. The toolbar simplifies the process of visualizing data, applying a legend, creating maps (average velocity, cumulative displacement, etc.), displaying time series and in-depth analysis with the Cross-section tool.
Cross-section mapping tool
The cross-section mapping tool allows users to observe the shape of the surface as it evolves over time and often reveals subtle discontinuities commonly associated with the surface expression of active faults. Simply drawing one or more vectors across the area of interest, an animation of the surface profile is generated.
Integration with different monitoring programs
Our data complement other ground monitoring systems such as GPS and levelling. A synergistic approach increases the effectiveness of monitoring and the accuracy of mathematical modelling. SqueeSAR™ allows the identification of thousands of natural measurement points (no in-situ equipment required) over the area of interest and their displacement in time.
TRE ALTAMIRA offers training courses to provide an outline of the latest radar satellite techniques, to demonstrate what they are capable of measuring and explain how to extract the most information from the results. Courses are attended for existing and potential end-users of the data, including geologists, geoscientists, engineers and public administration officers.
