Developer Agreement for Online Mapping Portal

The OS OpenSpace API (application programming interface) is a free service that allows users to build mash-ups of Ordnance Survey mapping. It was launched to the public in January this year and to date has over a thousand registered developers. The changes to the terms of use reflect the fact the components of the API are now available as a free open-source download - as OSGB Web Map Tools.  

Available from sourceforge.net, the tools allow Ordnance Survey data licensees to build commercial applications for the Web. At the same time as amending the OS OpenSpace terms in relation to OSGB Web Map Tools, Ordnance Survey has taken the opportunity to make some further changes that aim to provide greater overall clarity.

Key amongst the revisions is the introduction of new definitions of ‘Your Data' and ‘End User's Data' to complement what is already defined as ‘Derived Data'.  It is intended that the changes will clarify the position on ownership of each of these types of data, and will set out in clearer terms the various licences that are granted in relation to each of them.
