Thanks Harry for the wiki page. This is a severe flooding with high waters and lanslides in various areas. It is reported that more then 500,000 people have been evacuated in Bosnia alone.  More than 100,000 houses and other buildings
in Bosnia were no longer fit to use and that over a million
people had been cut off from clean water supplies. Support are organized by many other european coutries.
See an update from Reuters http://in.reuters.com/article/2014/05/19/balkans-flood-idINL6N0O522C20140519

If it is possilble to obtain the the polygons file from the http://balkans.aljazeera.net/vijesti/interaktivno-poplave-i-klizista-u-regiji map, A Task Manager job could be created for these areas.

With the large zone to cover, the best for the OSM community working remotely (I prefer this expression to the Armchair expression :) would be to cover the waterways and roadways to improve the base map.

Thx, I'll TRY to update it with some info.

Here is a map someone created which shows areas involved in floods
They approximate the area to be 22900 square kilometers.

Serbia: http://www.poplave.rs/
They switched to Google last night, but I sent a message to original 
author to ask him why and he didn't know it, someone else in the team 
changed it. He'll look into it who changed it and why and will bring OSM 

BiH: http://mapapoplava.zastone.ba/  & http://www.poplave.eu
They use ushahidi with OSM for few days now at first link, and now 
someone created new site in wordpress with only info.

Croatia: http://poplave.hr/
I asked them should we activate it for Croatia, they dind't reply and 
created one in wordpress because they didn't know how to start ushahidi.
IDIOTS!!! They were offered help!
And now when we ask them for locations they give me names od towns...

I have contacts in Serbia(where i'm currently) and in Croatia(where i'm 
from), but' dont have contacts from Bosnia.

I talked to people from http://mapapoplava.zastone.ba/ and they can give 
me csv export from their ushahidi site. Can that help to determin the 

My first objective is to map the areas as good as possible with 
available imagery so people can have better maps to report on those sites.
Only with new imagery and ground data will there be a possibility to map 
any changes.

On the ground data will be only available in later time when situation 
calms down.

Almost all the flood waters in Bosnia will flow into river 
Sava(Bosnian-Croatian border) and that wave is still going to hit that 
region harder and will flow into Serbia and hit some places again, and 
flow into Danube river.

Hope this info helps.

> Was http://www.poplave.rs originally using OpenStreetMap? They've swapped it to google maps now :-(  Any other examples of people using OpenStreetMap for coordination/situation maps?
