OS Terrain 5 is ideal for:

OS Terrain 5 is particularly valuable for large scale development projects, planning, impact assessment

OS Terrain 5 offers detailed modelling of significant features such as road, rail, quarries and lakes​ allowing you to asses the lie of the land on-screen and reduce the need for site visits. OS Terrain 5 has a root mean square error (RMSE) value of 1.5 metres in urban areas and major communication routes. 

OS Terrain 5 is maintained as part of the same revision process as the Ordnance Survey's large scale datasets and so adds a valuable third dimension to OS MasterMap Topography Layer.

OS MasterMap Graphic is a simple image-only version of OS Mastermap Topography Layer, the most detailed, current and comprehensive map dataset of Great Britain. When you only need an image of Mastermap and have no requirement to use it in CAD or GIS software, OS Mastermap Graphic is your best choice - a cost effective way of getting the image you need to use within document creation. Please note that OS Mastermap Graphic is a raster image only, with no georeferencing information, so isn't suitable if you need to measure distances.

OS MasterMap Graphic is ideal for:

• When you need an image of large scale mapping
• Using within word processing and graphic design programs
• Detailed site maps for brochures and guides
• Site location and evaluation
• Risk management
• Transport and infrastructure
• Asset management

OS Mastermap Highways Network® is the Ordnance Survey's latest and most comprehensive dataset of Great Britain's road network and is the next generation of the well-known product OS ITN. It is comprised of a suite of products that brings together the best information from authoritative sources in to one central location.

In addition to road centre lines and classifications, Highways features richer content that is better structured to allow for analysis as well as visualisation. Highways has been designed with traffic analysis, asset management, planning and the emergency services in mind, allowing users to plan for tomorrow. It gives you accurate and precise asset management information on who maintains the road network and the type of surface reinstatement values. And it's a valuable reporting tool, for key facts and statistics about the road, against a consistent and authoritative base.

OS Highways - Roads can be extended using OS Highways - Routing, and OS Highways - Paths

The OS MasterMap Networks - Water Layer®​ is the only detailed, heighted water network of Great Britain showing the flow and precise course of rivers, streams, lakes and canals.​ 

It offers the most accurate view of all watercourses across the whole of Great Britain created, in collaboration with the Environment Agency and Scottish Environmental Protection Agency, to a consistent specification and update schedule – so it can help support flood risk management decisions and the sharing of information between national and local organisations.

Accurate physical properties of watercourses enable modelling in 2D and 3D like never before, thanks to the clear and detailed information about river flow, gradient and river widths, along with its precisely mapped course.

The data maps a wide range of features, from aqueducts to tunnels with full flow direction and for the first time the network of underground watercourses – inferred from the entry and exit points.

The aerial images give added context to features which exist within other (vector) OS MasterMap layers and allow interpretation of other features not identified within the vector datasets. The data is rigorously checked for quality to maintain a consistent standard of both positional accuracy and image quality.

Additionally Ordnance Survey processing software produces true-orthorectified imagery, removing building lean from aerial imagery to give you a consistent top-down view.

Aerial imagery is ideal for checking road markings, tree canopies or site entrances, cutting down the need for site visits, so you can save money and manage time more efficiently.​

Purchasable as both a traditional raster cut-out of a user defined area or as web services.

​Emapsite LandPack Title and Tenure provides Emapsite LandPack Polygons plus OS MasterMap Topography Layer for a customer's area of interest.  The product indicates freehold and leasehold polygons and areas where no data is held (perhaps because ownership information is held in paper deeds, by a mortgage provider/solicitor or there is no owner) along with property information such as property type, built form and construction age plus current energy consumption, rating, efficiency and carbon dioxide (CO₂) emissions.

There may be more than one polygon per Title (e.g.  where a house with a garden has a garage located separately).  

You can purchase emapsite Land Title and Tenure through our online mapshop, where you can define your area of interest and purchase in a range of GIS formats.

Common uses:

​Ideal for project and site specific users in a variety of sectors where land parcel information is required, including planning, site development and asset management.​
