The images above were captured by the Sentinel-1 sensors (data courtesy EU/ESA) and processed using ENVI® SARscape®. The ability to observe theearth in any atmospheric condition as well as to shoot the same geographical area with the high temporal frequency, provided by the Sentinel-1 A and B sensors, not only allows us to capture the event in near-real time, but also to observe its evolution. These images show normal traffic in the Canal prior to the blockage, as well as the ever- increasing traffic jam to access the passageway that accounts for approximately 30 percent of container ship traffic globally each day.
Using ENVI SARscape and ENVI SARscape Analytics, ships can be distinguished on water due to their signal response with SAR data. SAR show ships as very bright points and areas as compared to the dark background of water. This is because of how the energy gets reflected. With this analysis, we can easily detect, count and track ships. In this case, we can see just how many ships are backed up waiting for passage through the Suez Canal. With Sentinel-1 15m ground range data we can even see the orientation of the Ever Given as it is lodged in the canal.
