bullet::::- "os mastermap" : ordnance survey's most detailed mapping showing individual buildings and other features in a vector format. every real-world object is assigned a unique reference number (toid) that allows customers to add this reference to their own databases. "os mastermap" consists of several so-called "layers" such as the aerial imagery, transport and postcode. the principal layer is the topographic layer.









































bullet::::- "os vectormap local" : a customisable vector product at 1:10,000 scale.









































bullet::::- "os landplan" : a raster map at 1:10 000 scale.









































bullet::::- "meridian 2", "strategi" : mid-scale mapping in vector format.
