Work has begun on OS MasterMap Topographic, the replacement for Ordnance Survey Land-Line, through the Digimap service.
OS MasterMap is a more complex data product and is structurally different from the Ordnance Survey data currently provided, so delivering it requires considerable investment and development work. Work is now under way to create a separate delivery application which will be available through the current service interface.
OS MasterMap currently contains four layers, each comprising various mapping features. Two of these layers, Topographic and Integrated Transport Network (ITN), will be available through Digimap. Each feature has its own unique identifier or TOID (Topographic Object Identifier), a 16-digit reference number that can be shared with other users across different applications and systems for easy data association and greater accuracy.
The published timetable for development work is as follows:
More details of the timetable will be published on the EDINA web site as the project continues.
Land-Line data will continue to be available via the current Digimap Download facility throughout the OS MasterMap development process and for one year beyond August 2007. This will allow users to complete projects using Land-Line, and allow institutions to make any changes required to support users of the OS MasterMap data. Land-Line maps, however, will cease to be available on 1 August 2007. The final update to Land-Line will be released in September 2006.
Over the last few years, EDINA has spent time ascertaining user requirements for supply of OS MasterMap data. A forum held in January 2006 reconfirmed and established priorities for previously identified requirements, and identified new ones. Further consultation was carried out via a survey on the EDINA web site. The 300+ responses are currently being processed in order to create the final requirements list. EDINA will soon be requesting institutions to volunteer as early adopters. Details of what you need to have and do to take part in the early adopter programme will be forthcoming. Please keep an eye on the web site below.
