Transport planners to benefit from emapsite polygon solution
emapsite is making it easier for road transport planners to harness the power of Great Britain’s most detailed topographic mapping data.
The geoportal, which supplies web mapping content for professional users, is offering an aggregated road polygon function to improve the flexibility of the OS MasterMap Topography Layer.
It means that users can interpret an entire stretch of road without it being split into the separate feature identifiers that show polygons at junctions and roundabouts.
Liz Scott, emapsite’s head of customer services, said: “We have created an intuitive solution that gives users more flexibility in how they visualise the individual map components they want to work on. The restructuring will save time when they are defining features for their project planning.”
The merged polygons are available in the DWG drawing file format, the most popular way for CAD users to receive OS MasterMap.
As well as transport planners, the improved polygon function will benefit civil engineers, logistics managers and other local authority technical managers.

Adopting Cloud computing can save money, but good governance is essential to manage the risk argues Mike Small
