Public Sector Geospatial Agreement (PSGA) customers can download their geographic chunk data for AddressBase and AddressBase Plus as well as a full supply of AddressBase Plus Islands via our download service.
The data is supplied as chunked files that cover your selected area. These files are named according to the convention shown below.
When you open your data, you will see a series of zip folders:
Using AddressBase Plus and Islands as an example:
AddressBasePlus_FULL_2020-01-21_001_csv.zip
(Full supply of GB CSV)
AddressBasePlus_ISL_FULL_2020-01-21_001_csv.zip
(Full supply of Islands CSV) or
AddressBasePlus_COU_2020-01-21_001_gml.zip
(COU supply of GB GML)
AddressBasePlus_ISL_COU_2020-01-21_001_gml.zip
(COU supply of Islands GML)
Using AddressBase Plus as an example:
AddressBasePlus_FULL_2011-07-29_TQ2020_csv.zip
(Full supply of CSV) or
AddressBasePlus_COU_2011-07-29_TQ2020_gml.zip
(COU supply of GML)
The AddressBase Plus Islands product is not available in geographic chunks.
The GML and CSV data is supplied in a compressed form (ZIP). Some software can access these files directly, while other software will require the files to be unzipped.
To unzip the zipped data files (.zip extension), use an unzipping utility found on most PCs, for example, WinZip. Alternatively, open-source zipping/unzipping software can be downloaded from the Internet, for example, 7-Zip.
When you unzip the files, the data will be extracted as CSV files, which are ready to use. For example, unzipping AddressBase Plus will extract files similar to the chunks below:
AddressBasePlus_FULL_2020-01-21_001.csv
AddressBasePlus_ISL_FULL_2020-01-21_001.csv
AddressBasePlus_2011-07-29_NC4040.csv
