The south Indian city of Chennai is facing one of the biggest floods in a century with close to 120 cm rainfall this month. It has already claimed 200 lives and has affected the lives of over 6 million residents. The meteorological department has forcasted more rain in the next 48 hours and the situation has been termed crucial.
Members of the Indian OSM community created tool to crowdsource reports of flooding, and has recieved reports of over 5700 flooded streets in 48 hours. Check the flood-map to see the extent of flooding in the city.
The inner city part of Chennai city is well traced but the outskirts still miss a lot of details in road network. We have setup a project on the tasking manager to trace out these missing roads and waterways.
Please join the project when you get time to improve the road coverage around Chennai which can be used to report more flooded streets: http://tasks.openstreetmap.in/project/62
