SAR Data In Combination With Other Analyses

Updated: Jul 5

In Episode 2, Iphigenia taught us all about the capabilities and limitations of SAR analysis. Indeed, SAR analysis is at its optimal when used in conjunction with other types of data analysis. Let’s take a closer look at some examples.

Hydrological Data

SAR can be used alongside hydrological data to provide insights into the dynamics of surface water, for example. SAR data can be used to measure the surface roughness of water bodies, which can in turn be used to estimate water depth and identify changes in water levels over time.

By combining SAR and hydrological data, engineers can gain a more comprehensive understanding of water dynamics in a given area, which can be used to inform the design of infrastructure such as dams and bridges.

Geotechnical Data

Geotechnical data and observations can also be used in conjunction with SAR analysis to provide insights into subsurface characteristics. SAR data can be used to identify changes in surface deformation, which can be indicative of subsurface movement or instability.

Geotechnical data such as soil composition or rock density measurements can be used to verify these observations and provide additional information on the subsurface conditions.

By combining SAR data with geotechnical data, engineers can acquire insights into the potential risks associated with subsurface movement, which can be used to inform the design of infrastructure projects such as tunnels and pipelines.

Topographical Data

With these two data complementing one another, a more detailed understanding of terrain can be provided. SAR data can be used to identify any changes in surface elevation, which can be used to create detailed topographical maps of the area. From here, elevation models and slope maps can be added to corroborate these observations and provide additional context for the results. Projects such as roads and railways can be better informed by considering a combination of these analyses.

Civil Engineering Data

Insights into the structural integrity of existing assets can be obtained through this coupling. SAR data can be used to identify changes in surface deformation which can be indicative of structural damage or degradation. Civil engineering data such as inspection reports and structural analysis results can be used to verify these observations and provide additional information about the condition of existing infrastructure. Engineers can gain a better understanding of potential risks associated with existing infrastructure which can be used to inform maintenance and repair efforts.
