This interactive map will show the MAXIMUM flood height during the onslaught of typhoon Ondoy. Please help us in gathering data by entering information the maximun flood height you have observed in your area. Click the image below to enter the data.
When completed, this can serve as a guide for identifying future floods in Metro Manila and can validate flood simulations.
The satellite images show the before and after of the affected areas caused by typhoon Ondoy.
