Data formats

The AddressBase Core product is distributed as a Comma Separated Value (CSV) file or GeoPackage (GPKG). CSV files can be supplied as a Full Supply or Change Only Update (COU) when taking Managed Great Britain Sets (MGBS); or Full Supply or changed tiles when taking tile supplies. GPKG is only available as Full Supply for both MGBS and tile supplies.

CSV

The CSV format of AddressBase Core means:

1. Column headers are included in the file.

2. There is one record per line in each file.

3. Fields are separated by commas.

4. No comma is placed at the end of each row in the file.

5. Records are terminated by carriage return/line feed.

For MGBS orders, one file containing all records is produced.

GPKG

GPKG is an open, standards-based, platform-independent data format for transferring geospatial information as defined by the Open Geospatial Consortium (OGC). It is designed to be a lightweight format that can contain large amounts of varied and complex data in a single, easy-to-distribute and ready-to-use file.

GPKG offers the following benefits:

1. The single file is easy to transfer and offers the end-user a rich experience.

2. Attribute names are not limited in length making it customer friendly.

3. No file size limit, so lots of data can be easily accommodated.

4. Supports raster, vector and database formats making it a highly versatile solution.

5. Conforms to OGC standard.

6. In most cases, it is a Plug and Play format.

For both MGBS and tile supplies, GeoPackage supplies will be provided as one file.
