Due to an ongoing issue with the European Space Agency's Sentinel 1 B satellite, we are not capturing Sentinel 1 imagery over all locations at the usual frequency. We apologise for this unanticipated degradation in image capture. More information is available here.
We are currently rolling out a small update to Data Services. We do not anticipate any interruption to your service, however if you do experience any difficulties please let us know using the feedback tab.
