Scalable Geospatial Object Database Systems

By Adrian Marriott

August 3, 2006 Abstract: The purpose of this paper is to describe the Geospatial Object Server (GOS) that lies at the heart of the OS Master Map project deployed Ordnance Survey in the UK. The aim of OS Master Map is to underpin all commercial and government activity that involves spatial data into the next millennium. Here we describe what the GOS does, why it does these things and how it is implemented to scale to billions of objects. We also look at project risks and business benefits. The Geospatial Object Server (GOS) holds the largest, seamless spatial dataset in the world, covering the whole of the UK at 1:10000 scale. Its primary task is to supply this data in various XML formats in response to queries.
