Ordnance Survey - OS OpenData
Copyright Free Mapping:
In our opinion, OS Opendata is one of the most radical approaches to sharing mapping data in recent years.
OS Opendata is available to all, and is simply the provision of useful mapping information from Ordnance Survey free of charge.
Your organisation may order all of the OS Opendata should it so wish, or simply choose certain datasets such as the 1:250,000 raster map layers
Find out which layers are available on the Ordnance Survey Website Opendata pages.
If you would like help in ordering, translating or using OS Opendata, then that's where we are able to help you by managing it all for you. Please contact us if you would like further information.
