Products and Applications

Big data from remote sensing can be used for urban traffic modeling. Traffic models can be valuable tools for analyzing, predicting and ultimately controlling traffic and thus be an aid to effective decision making at various levels.

The effect of the warming of urban areas compared to adjacent non-urbanized areas is defined as urban heat island. This effect may be characterized from thermal infrared (TIR) remote-sensing data.

The total area covered by the world’s cities is set to triple in the next 40 years. Urban sprawl is a term designating the phenomenon of urban development, on the outskirts of cities. Also referred to suburbanization, less pejorative term. According to the European Environment Agency, sprawl occurs when , in a given area, the increase in urban land exceeds the progression of population.
Whether in the context of the spatial approach or temporal approach, remote sensing is necessary in research on urban sprawl. The maps obtained after the processing of remote sensing data provide quantitative and qualitative tools to characterize urban sprawl and to contribute to the management of spatial growth of cities.

Subsidence is the motion of a the Earth's surface as it shifts downward relative to a datum such as sea-level.
Subsidence has both natural and anthropogenic origin:
- Natural land subsidence is the result of deep downward tectonic movement.
- Anthropogenic land subsidence is induced by human activities.
Interferometric Synthetic Aperture Radar (InSAR) is a powerful tool in remote sensing, widely used to map land subsidence over wide regions.

Recently, we have also demonstrated that radar images could be also used to monitor structure deformations.
