GIS SolutionsThe use of geographic information enables data to be analysed using geographic criteria such as location. You may have a database of customers and understand the profile described by the attribute data you hold, but using your customers address to geographically locate them you can understand where your customers are in relation to your offices or distribution centres. GI offers a new dimension to the knowledge that can be gained through analysis of your data with vast possibilities limited only by the depth and quality of the source data. It has been estimated that a significant proportion of all information currently held contains a geographic element. The majority of data relates to individuals and/or businesses both of which have an address. The UK is fortunate to have a well-structured postcode system that is managed by the Post Office for the purpose of aiding mail delivery. At its lowest level the unit postcode describes either a small cluster of mail receiving households/businesses, or where there is a significant amount of mail to a singular address, it is uniquely allocated a postcode. See IT have the ability to clean address records to ensure that they match those of the Post Office's Postal Address File and subsequently determine the co-ordinate location of the address. Working geographically, each address is represented on a map and can be used to analyse or display attribute information from the underlying database. Our Services section provides more information on the potential for geographic information. Case Study - Map Production for inclusion in regional sales pack. Our client, a major financial institution operating internationally, required data relating to Point of Sale transaction volumes to be presented in map format. Their purpose was to assess the distribution of transaction volumes across a country and/or continent. See IT cleaned the data against a gazetteer of world place names with 350,000 entries and added the required co-ordinates to the entry for each location. Using a geographic information system we 'themed' the map to represent the magnitude of transaction volumes in each location. This process establishes the maximum and minimum values for the given data-set and produces an object on the map to represent the magnitude of transaction volume at that location. The exercise included map production for 15 countries over 3 continents. |
