## Download data products

OS produces two types of **Download data product**: Premium and OpenData:

* Premium products refer to paid-for datasets – whether they’re paid for by businesses, purchased through an [OS Partner](https://www.ordnancesurvey.co.uk/customers/os-channel-partners), or accessed by registered members of the [PSGA](https://www.ordnancesurvey.co.uk/customers/public-sector/public-sector-geospatial-agreement) under the terms of their member license.
* OpenData products are free to use by anyone for any purpose – including for services from which you make a profit.

Download data products are grouped by portfolio: [Addresses and names](#addresses-and-names), [Areas and zones](#areas-and-zones), [Buildings and infrastructure](#buildings-and-infrastructure), [Land and terrain](#land-and-terrain), [Maps and imagery](#maps-and-imagery), [Transport network](#transport-network), and [Water](#water).
