| The Data Directory - UKSGB | |||
 |
|||
| The
UK Standard Geographic Base (UKSGB) aims to provide access to commonly used
geographical units in the UK. The geographical base units currently included
in the UKSGB and available via the Data Directory are: These administrative and postal geographies are constructed from a separate hierarchy of areas, the units of which 'nest' together. The division of the UK is based around standardised, fundamental building blocks, or CORE SPATIAL UNITS. This is the most important aspect of the UKSGB. These datasets are available from a range of sources but what makes the UKSGB and the Data Directory important is the emphasis they place on standards. For operational reasons, postcodes sometimes change and ward boundaries are revised periodically for electoral purposes. As a result, data often doesn’t match up with the core spatial units. |

Figure

Local Authority districts, parliamentary constituencies and other geographies.

The Data Directory offers you access to and information about a range of definitive UKSGB datasets directly from the dataset custodians themselves. These datasets contain information such as up to date names, codes, boundaries, and map co-ordinates for each of the core spatial units. The Data Directory also aims to build up an archive of old versions so that your historical data can be mapped into the spatial base on which they were collected. |
