Data ordering and currency

To get access to the OS NGD you must first log into the OS Data Hub. The OS NGD will be accessible via both the Premium Plan and Public Sector Plan on the OS Data Hub.

Geographic filtering

There are three options within OS Select+Build in relation to the geographic extent of your order. These are:

• Great Britain: Receive all data for the whole of Great Britain.

• Customer Specified Area: Draw an area of interest (AOI) and only receive the data which intersects this area.

• Pre-defined Area: Select a pre-defined area, and only receive the data which intersects this area.

Order update options

When accessing the OS NGD, the following order update options will be available:

• One Off Full Supply

• Regular Full Supply

• Change-Only Update (COU; after an initial Full Supply)

• No Update

The following frequencies will be available dependent on the type of order you place:

• Daily Supply: This will provide you with the latest updates OS have loaded and verified for publication since the previous day as a COU file.

• Monthly Supply: Either a Full Supply or COU Supply of all the changes which have occurred in the previous month.

• Annual Supply: A Full Supply of the data to show how the data looked at the end of each year.

Further details about the options available to you can be found further down on this page.

Update files

If you choose to receive a COU supply for your CSV data, this can be provided on either a daily or monthly frequency. In both cases, your COU file will contain any changes which have been made to the underlying data within the selected time frequency. If no changes have been made to a selected feature type of your choice, then you will receive a blank COU file.

File supply

If you use OS Select+Build to access the OS NGD, then a separate download file will be provided for each feature type you order. For example, if your selected theme has two feature types you will be supplied with two separate files (CSV or GeoPackage) as part of your order.

Ordering combinations

The following tables summarise the different options available to you dependent on what you specify when ordering your data through OS Select+Build.

For the purposes of the tables below, the following definitions are being used:

• Unfiltered means a Great Britain supply with no further attribute filters applied.

• Filtered means an order for data which either has a geographic filter applied or an attribute filter applied.
