Online maps have already changed the way we move around in the world. But now, a project called U-Flood promises to show us exactly how bad the flooding from Hurricane Harvey really is.

The project, by consultants at the environmental firm Marine Weather and Climate and the tech company Tailwind Labs, is an interactive map of flooding in Houston as well as other cities like Galveston, Baton Rouge and New Orleans. It relies on the community to update the map, and so far has received more than 1,500 reports. Currently, it's counting 991 roads inundated in Houston as a result of Hurricane Harvey.
