The BBC Domesday system was supplied with two laserdiscs:
The Community Disc contained personal reflections on life in Britain and is navigated on a geographic map of Britain. The entire country was divided into blocks that were 4 km wide by 3 km tall, based on Ordnance Survey grid references. Each block could contain up to 3 photographs and a number of short reflections on life in that area. Most, but not all, of the blocks are covered in this way.
The National Disc contained more varied material, including all data from the 1981 census, sets of professional photographs and virtual reality-like walkarounds shot for the project. The material was stored in a hierarchy and some of it could be browsed by walking around a virtual art gallery, clicking on the pictures on the wall, or walking through doors in the gallery to enter the VR walkarounds. In addition a natural language search was provided via an English stemming and matching algorithm to a set of keywords.
Our discs together with the BBC Countryside and Eco disks were kindly donated by Keith Bowman together with the original laserdisc player and the
BBC Micro
