Floods in Rockhampton - before and after
The image above right shows the devastating impact of flood waters on the town of Rockhampton, Queensland, Australia. It was taken on 5 January, when the Fitzroy River was at its peak level of 9.2m.
The image was created using radar data collected by the Cosmo-SkyMed satellite constellation, operated by the Italian Space Agency. The satellites are capable of taking images day and night, as well as through clouds. The flood maps are made available to assist emergency services in their work.
The flood data was overlayed on an existing optical satellite image of the Rockhampton area by BBC News.
