TPI Tuesday – Monitoring long-lasting groundworks: SAR edition

Last week’s TPI-Tuesday showed a long-lasting road construction activity. This week, we would like to display the radar data that accompanied this activity. The change detection of the CoSMiC-EYE system is currently primarily based on SAR data. For the classification of the changes, we use optical images.

CoSMiC-EYE is thus perfectly capable of monitoring the activity by actively tasking for high-resolution optical imagery in the area, but also the SAR data enables to keep locating the changes. The radar pictures at the bottom left show processed Sentinel-1 SAR images of the area. The change map at the top shows the difference in the SAR imagery over time.
