Why Geocoding?   Geocoding one’s address data is essential for the successful implementation and use of Geographical Information Systems (GIS). Since each record in the NLPG contains an Easting and Northing map reference, iMatch can be used to transfer these coordinates to other address databases. This gives the ability for a department’s data to be viewed spatially and facilitates a new and accurate method of data management with changes to the map data leading to changes in the database and vice versa.

Geocoding is generally achieved through an initial pass in automatic mode, followed by one or more passes in interactive mode - reviewing only the records that have not already been geocoded.

In the Fire & Rescue Service the advantages of geocoding are:

• It allows for the mapping of arson attacks, historical fire data, lightening strikes etc., which can be used to gauge the likelihood of future fires

• It allows for the mapping of anti-social behaviour against fire fighters/fire appliances allowing for appropriate preparation in advance of mobilisation

• It means flood risk areas can be mapped against times of years to ensure better preparedness during certain periods in certain areas

• It enables the mapping of higher priority locations e.g. properties close to petrol stations

In Local Government the advantages of geocoding are:

• It allows for the mapping of public services e.g. schools, recycling sites, churches etc

• It allows for the mapping of anti-social behaviour orders

• It enables Electoral Services to map voting registration

• It enables the mapping of empty properties for the identification of possible regeneration areas
