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 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.

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.

Licence: PDF

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.​

​emapsite Commercial Land Ownership combines OS MasterMap with non-privately owned land ownership data, taken from HM Land Registry's National Spatial Dataset and Commercial and Corporate Dataset. The polygon attributes include the name of the organisation registered as the title owner, company registration number, type of organisation, title number and tenure of the land parcel in question.

emapsite Commercial Land Ownership allows asset managers to make one simple purchase to cover their large scale mapping needs rather than having to make individual purchases of HM Land Registry data. Asset managers in the housing association, commercial and public sectors can request the polygons and title data on all their holdings, sorted by organisation name or company number.

Purchasable as a user defined area through our online mapshop, and deliverable in a range of GIS formats.

Licence: PDF

Key Facts

• A subset of the polygons in emapsite Land Title and Tenure, with extra attributes
• Polygons for all land titles registered with Land Registry which are not owned by a private individual, a charity or a company registered overseas. Includes estate in land owned by:
  • Limited or Public Limited companies
  • Local and Central Government (e.g. council land, MOD)
  • Church lands, universities, independent schools
  • Housing associations (all their housing stock)
• Contains a polygon plus the following attributes in both a GIS file and a CSV:
  • Address - based on OS address data past or present
  • Proprietor (owner) name and company registration number
