Building Height Attribute (BHA) is a dataset consisting of a number of different height attributes for each building in OS MasterMap Topography Layer. The height attributes provided for each building are:
Using these three values two additional relative heights are calculated:
BHA is available as an alpha release from OS who do not guarantee that the dataset is error free or accurate. Additionally the dataset is not subject to update and maintenance. However in time OS intend to include BHA in OS MasterMap Topography Layer so in future it will be supplied and maintained as a part of the Topography Layer.
Please note: BHA data is not currently available for the whole country; the current alpha release of BHA covers around 10,000km2 of the major towns and cities in Great Britain. You should consult the interactive map published by the OS to see if data exists for your area of interest.
