The system of flood risk zones was developed by Czech Insurance Association in cooperation with Intermap Technologies in 2002-2003 in order to assess the risk of flooding by Czech Insurance Association members. The flood maps were devised with a contribution by the global reinsurer Swiss Re. Map data are regularly updated to be consistent with the information used by Czech Insurance Association members.
