UK Government to Make Parts of Ordnance Survey (OS) MasterMap Freely Available

From the Ordnance Survey:

As part of the Prime Minister’s London Tech Week roundtable today, the Government has announced that key parts of the OS MasterMap will be made openly available for the public and businesses to use.

It is estimated that this will boost the UK economy by at least £130m each year, as innovative companies and startups use the data. This is a step on a journey towards more open geospatial data infrastructure for the UK.

The datasets that will, upon implementation of the policy changes, be available under the Open Government Licence (OGL) are:

  • Property extents created from OS MasterMap Topography Layer; and
  • OSMM Topography Layer TOIDs (TOpographic IDentifiers) will be incorporated into the features in OS OpenMap-Local.

The datasets that will be made available for free, up to a threshold, through an API are:

  • OS MasterMap Topography Layer, including building heights and functional sites;
  • OS MasterMap Greenspace Layer;
  • OS MasterMap Highways Network;
  • OS MasterMap Water Network Layer; and
  • OS Detailed Path Network.
