Routing Capability Added to Ordnance Survey Map Data

Users of Cadcorp SIS web mapping and geographic information systems software will be able to get even more value from their free to use Ordnance Survey Meridian 2 mapping data for Great Britain. Thanks to a new plug-in, SIS users will be able to view the roads of Great Britain as backdrop to their mapping applications, and to navigate those roads as part of a topologically structured transport network. Cadcorp is providing this enhanced capability free of charge.  

The new plug-in takes advantage of the link and node metadata from the Meridian 2 database and builds a topological network from the different feature layers, even though the underlying data format is not topological. A user can simply point SIS at a folder containing Meridian 2 Esri Shape files and let it run. As SIS reads the data, it automatically processes it into a topological network.
