In late July 2018, severe flooding affected the Indian state of Kerala due
to unusually high rainfall during the monsoon season.
It was the worst flooding in Kerala in nearly a century.Over 373 people
died within a fortnight, while at least 280,679 people were evacuated. It
is estimated that 1,247,496 people have found shelter in various relief

Disaster response websites using OpenStreetMap are the following:
    * is used to identify flooded roads -
    * used to visualise rescue requests - ,

Facebook released road data generated with machine learning in Kerala  and
they offered help to mobilize their team to the data in OSM.
Please see the discussion here:

Our proposed plan is to allow FB mapping team to do the initial import
using their internal tools that takes care of conflation, connectivity
fixes, etc.
OSM-India community will then validate the imported data focusing on the
highway tagging following the India road tagging scheme:

Looking forward to your comments and suggestions.
