Building Heights data for licensed OS MasterMap


Reprocess your licensed OS MasterMap to access free Building Heights data.

The Ordnance Survey has started adding building heights data to its OS MasterMap topography layer. Building Heights data gives the height above sea level of the base of the building as well as the relative building height, providing you with a valuable third dimension for GB data at no additional cost. Some of our customers are telling us it provides a useful starting point to enable powerful visualisation of developments and the tests we have run confirm it complements digital surface models such as LiDAR really well.

emapsite now processes the data automatically, so when you buy OS MasterMap you’ll get the Building Heights data if it’s available. What’s more, if you’ve already licensed OS MasterMap data through us, you’re welcome to reprocess that data in a choice of formats on the website with Building Heights for free. Just go to 'My Account' to access your licensed data and click ‘Reprocess’ next to your OS MasterMap download.

There isn’t full countrywide coverage (currently still mostly urban) so it’s not available for all areas. If there is data for your area there will be an additional download link supplied with your OS MasterMap download and if not rest assured the OS are continually adding to the existing data and we make that available as soon as we get it from Ordnance Survey.
