Washington, Nov. 24 -- : Researchers at The University of Queensland have used satellites with radar imaging sensors to see through clouds and map flooding and say the technique could provide faster, more detailed information to keep communities safe.

Professor Noam Levin from UQ's School of Earth and Environmental Sciences said the project combined images from optical satellites with information from imaging radar satellites.

"Monitoring floods in towns and cities is challenging, with flood waters often rising and then receding in a few days," Professor Levin said.

"While large satellites in the past provided images every 7-14 days, now groups of small satellites can collect several images a day over the same location.
