Australian Floods on Google Maps
Geoscience Australia's Flood Map is using Google Maps to present data on historical flood mapping in Australia derived from satellite imagery.
The current map is a proof of concept which over the next two years will be developed into a nationwide portal to provide data on flooding which has been observed by satellite since 1987. The current map shows flooding data from MODIS images from 2000 to 2012. Because of cloud cover in satellite imagery the flood data is produced from eight days of satellite imagery.
The water data displayed on the map is detected from the satellite images using an automated flood mapping algorithm created by Geoscience Australia.
