People living close to the River Calder have experienced severe flooding in recent years and local authority emergency planners were keen to see how geographic information might support the understanding of the number of properties affected, the location of vulnerable people and provide a ‘head start’ regarding the location of rest centres and the organisation of appropriate transportation.
Now if there is a flooding incident, geographical information systems (GIS) are used to give a visual and analytical overview of the properties and people affected using the Environment Agency™ flood-warning boundaries, Ordnance Survey digital maps and Calderdale Council’s Local Land and Property Gazetteer (LLPG).
The data is securely made available to key staff that can query the location of all known vulnerable persons and this is an efficiency saving that has the potential to save lives. Without GIS, it would take four hours to cross-reference and identify the vulnerable persons already known to the council who have been affected by a given emergency.
By applying GIS and the LLPG, response time is improved dramatically, but cross-referencing is still required. By linking the council’s vulnerable persons database to GIS, results are reduced to a minute. Their MBX tool now delivers a response from multiple datasets in minutes.
- Massive time-saving locating known vulnerable citizens during emergencies.
- Instant location of affected properties.
- Improved location intelligence for decision-making (evacuation routes and access/rendezvous points).
