Product packaging

When a customer receives an order from the OS Data Hub, the product will be packaged with the following elements:

Data folder

The data folder will contain the GML, GeoPackage or vector tiles files which make up the ordered product. The data folder will have been compressed to data.zip to enable a single download of the product. Once this has been downloaded, the data.zip file will contain all the data files which make up the ordered product and these files will have been compressed using gzip.

Doc folder

For GML, the doc folder will contain a summary.gml file which will contain specific information about the customer order, including:

• The order number

• Query extent polygon(s) of the order

• The order type: Full Supply or COU

• For COU orders, the change-since date

The doc folder will have been compressed to doc.zip to enable a single download of the associated documents.

The GeoPackage and vector tiles formats will have the same folder structure, but will be available for Great Britain coverage only, so will not contain COU files.

Resources folder

The resources folder will contain the product’s Feature Validation Data Set (FVDS), and a lookup table to the OS Open Roads product. The folder will have been compressed to resource.zip to enable a single download of the resources; within the zipped folder, the contents will have been compressed.
