Professor Mahar Lagmay and his team at the National Institute of Geological Sciences at the University of the Philippines is attempting to record the level of floodwaters experienced during Ondoy.
They have put up a Google Map online for people to pinpoint where the floods happened and how deep they got.
It is important that people immediately document their experiences before time makes them forget. If you have a google account or gmail, you can put placemarks on the map. Sign in, place your cursor on the map, right click, and choose "placemark".
Please pass this on... Thanks!
