AddressBase Premium Islands is supplied as non-geographic chunks only. This is a way of dividing up the data into chunks that are supplied in separate volumes, which have a fixed maximum number of records. The supply is not supplied with any reference to the geographic position of records.

Customers are able to take the AddressBase Premium Islands product as a full supply or a change only update (COU) supply for GML and CSV formats. The AddressBase Premium Islands GPKG is available as a full supply only.

Unzipped files

When you receive your data, the filename will be constructed as follows:

• productDescription_supply_ccyy-mm-dd_vvv.format

  • productDescription: AddressBasePremium_ISL

  • supply: FULL or COU

  • ccyy-mm-dd: the date the file was generated

  • vvv: volume number of the file

  • format: file format of the files received, for example csv, gmlL or gpkg

For example:

• AddressBasePremium_ISL_FULL_2015-10-28_001.gml (GML full supply)

• AddressBasePremium_ISL_COU_2015-10-28_001.csv (CSV COU supply)

• AddressbasePremium_ISL_FULL_2015-10-28_001.gpkg (GPKG full supply)

Zipped files

If the data has been provided in a ZIP file, the filename will be constructed as follows:

• productName_supply_ccyy-mm-dd_vvv_format.zip

For example:

• AddressBasePremium_ISL_FULL_2013-05-28_001_gml.zip (GML full supply zipped)

COU supply

AddressBase Premium Islands is available as a full or change-only update (COU) supply for CSV and GML formats. COU supplies are not available for GeoPackage format.

A COU supply of data contains records or files which have changed between product refresh cycles. The primary benefit in supplying data in this way is that data volumes are smaller, reducing the amount of data that requires processing when compared to a full supply.

COU data enables a user to identify three types of change:

1. Deletes (CHANGE_TYPE ‘D’) are objects that have ceased to exist in your area of interest (AOI) since the last product refresh.

2. Inserts (CHANGE_TYPE ‘I’) are objects that have been newly inserted into your AOI since the last product refresh.

3. Updates (CHANGE_TYPE ‘U’) are objects that have been updated in your AOI since the last product refresh.

Archiving

When users are deleting, inserting or updating features, it is up to the user to consider their archiving requirements. If deleted records are important to your business requirements, you must take appropriate action to archive previous records.

This release note provides information about the June 2024 release of the AddressBase Islands products. These products were released to customers on 27th June 2024.

Record Counts

Changed Records

If you receive a Change-Only Update (COU) supply for your AddressBase Islands product, you will receive Insert, Update and Delete records within the supplied file. The following tables detail the count of these records.

AddressBase Plus Islands

AddressBase Premium Islands

It is important that COUs are processed with Deletes first, then Inserts and Updates. This is to ensure that updates are applied in the correct order. Guidance on this can be found in the Getting Started Guide – AddressBase, AddressBase Plus and AddressBase Plus Islands in the AddressBase general documentation.

Source Data Currency

The following information relates to the currency of the source data used in the creation of Epoch 111:

Data Issues

AddressBase Plus Islands Issues

There are no reported issues in this release of AddressBase Plus Islands.

AddressBase Premium Islands issues

Affected output formats: CSV and GML

• Street incorrect coordinates – There are two Streets which have incorrect start or end coordinates of 000000. The unique identifiers can be provided upon request through your OS Relationship Manager.

Next Release

The next release of AddressBase Islands products, Epoch 112, is scheduled for 15th August 2024.

The AddressBase Premium Islands product is distributed as comma-separated value (CSV), Geography Markup Language (GML) version 3.2.1 or GeoPackage (GPKG) formats. The CSV and GML formats can be supplied as a full supply or a change-only update (COU); the GPKG format is available as a full supply only.

CSV

The CSV supply of AddressBase Premium means:

• There will be one record per line in each file.

• Fields will be separated by commas.

• String fields will be delimited by double quotes.

• No comma will be placed at the end of each row in the file.

• Records will be terminated by Carriage Return / Line Feed.

• Double quotes inside strings will be escaped by doubling.

Where a field has no value in a record, two commas will be placed together in the record (one for the end of the previous field and one for the end of the null field). Where the null field is a text field double quotes will be included between the two commas, for example - “”.

AddressBase Premium CSV data will be transferred using Unicode encoded in UTF-8. Unicode includes all the characters in ISO-8859-14 (Welsh characters). Some accented characters are encoded differently.

The transfer will normally be in a single file, but the data can be split into multiple files using volume numbers. AddressBase Premium records are provided within continuous files cut at approximately 1 million lines as referred to above.

Street and Street Descriptor records are provided together and then a new file is started independent of count for the additional record types.

This means different record types, for example, BLPU and LPIs (see ) can be found in the same CSV file.

The record types are provided in the following order:

• Street (Type 11)

• Street Descriptor (Type 15) – a new file is started after the last Street Descriptor record for your supply is reached

• BLPU (Type 21)

• LPI (Type 24)

• Delivery Point Address (Type 28)

• Organisation (Type 31)

• Classification (Type 32)

• Application Cross Reference (Type 23)

GML

The GML 3.2.1 specification provides a set of schemas that define the GML feature constructs and geometric types. These are designed to be used as a basis for building application-specific schemas, which define the data content.

The application schema uses the following XML namespaces:

Features

Each feature within the AddressBaseSupplySet:FeatureCollection is encapsulated in the following member element according to its feature type:

BLPU

• Feature Type: BasicLandPropertyUnit

• Member Element: <abpr:basicLandPropertyUnitMember>

The UPRN of the feature is provided in the XML attribute of the gml:id

Street

• Feature Type: Street

• Member Element: <abpr:streetMember>

The USRN of the feature is provided in the XML attribute of the gml:id

Envelope

In the GML supply, you can determine the extent of your supply by the <gml: Envelope>. Because Latitude and Longitude are the mandatory coordinates in AddressBase Premium Islands the envelope uses these coordinates. For example:

GPKG

GPKG is an open, standards-based data format 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. Please be advised that older versions of GIS software may need updating before being able to display and interact with GPKG files.

GPKG offers the following benefits:

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

• Attribute names are not limited in length, making it user friendly.

• The file size limit is very large at 140 TB1, so lots of data can be easily accommodated.

• It supports raster, vector and database formats, making it a highly versatile solution.

• It is an OGC Standard.

• In most cases, it is a plug-in-and-play format.

The AddressBase Premium Islands product contains Local Authority, Ordnance Survey and Royal Mail addresses. This includes provisional addresses (proposed planning developments) and historic information (demolished properties), where available.

Ordnance Survey addresses are added to the AddressBase Premium Islands product where necessary to ensure the schema meets the core AddressBase products.

Building name

The building name is a description applied to a single building or a small group of buildings, such as Highfield House. This also includes those building numbers that contain non-numeric characters, such as 44A.

Some descriptive names, when included with the rest of the address, are sufficient to identify the property uniquely and unambiguously, for example, MAGISTRATES COURT.

Sometimes the building name will be a blend of distinctive and descriptive naming, for example, RAILWAY TAVERN (PUBLIC HOUSE) or THE COURT ROYAL (HOTEL).

Postcode

A postcode is an abbreviated form of address made up of combinations of between five and seven alphanumeric characters. These are used by Royal Mail to help with the automated sorting of mail. A postcode may cover between 1 and 100 addresses.

There are two main components of a postcode, for example, NW6 4DP:

• The outward code (or ‘outcode’). The first two–four characters of the postcode constituting the postcode area and the postcode district, for example, NW6. It is the part of the postcode that enables mail to be sent from the accepting office to the correct area for delivery.

• The inward code (or ‘incode’). The last three characters of the postcode constituting the postcode sector and the postcode unit, example, 4DP. It is used to sort mail at the local delivery office.
