We are pleased to announce the addition of two new datasets to the Digimap Ordnance Survey Collection, which are available to download through the Data Download application. Both these datasets are detailed network datasets and form part of the OS MasterMap family of products. The datasets should prove useful for individuals carrying out detailed network analysis using the road and river network of Great Britain.

OS MasterMap Highways Network

OS MasterMap Highways Network is a new dataset from Ordnance Survey which provides the most detailed road network dataset available for Great Britain. The new Highways Network product is a replacement for OS MasterMap Integrated Transport Network (ITN), which will be retired at some point in the future. Highways Network was built using ITN as the base network and then further improved adding information from other authoritative sources including the National Street Gazetteer (NSG) and local authorities in England and Wales.

Highways Network is provided in GML format as a single, national dataset covering the whole of Great Britain. This is a large dataset and is available through Digimap as a single download of 1.1GB in size.

Ordnance Survey have produced a number of supporting documents that are available for download directly from their website. We recommend that you consult these before using the data.

Current version: June 2016

OS MasterMap Water Network Layer

OS MasterMap Water Network Layer is a new network dataset from Ordnance Survey that represenets the centrelines of watercourses including flow direction and suplementary information.

OS MasterMap Water Network Layer is provided in GML format in 5 x 5km tiles. Water network features that cross tile boundaries are included in all tiles that they cross, so the data is called ‘hairy data’ due to the presence of these ‘hairs’ around the edge of each tile. This means that some processing is required to de-duplicate the features that cross tile boundaries if your order contains data from more than one 5 x 5km tile.

OS MasterMap Water Network Layer is projected in the ESPG 7405, which is a British National Grid projection that also includes the Z value using Ordnance Datum Newlyn.

Ordnance Survey have produced a Getting Started Guide which describes the process of importing the Water Network Layer in to common GIS packages.

This summer our cartographic team have been busy working on a new style for OS MasterMap Topography layer. These are the maps displayed at the three most detailed zoom levels in Digimap OS Roam. The original style, created more than ten years ago, followed the official style published by Ordnance Survey and has undergone little change since its creation. Later this year Ordnance Survey are making significant changes to the underlying MasterMap data so we thought it was high time the cartography was refreshed to give it a more modern feel.

The design brief had three broad requirements:

  • make it look ‘nicer’!
  • tone down the colours to allow annotations to stand out more
  • use the same colours as OS VectorMap Local, the second most detailed data product

The images below show the original and new styling for a number of areas which highlight the improvements that have been made in both urban and rural areas.

Changes to styling in urban areas:

MasterMap urban original stylingMasterMap urban new styling

The colours in urban areas have been muted, removing the large areas of yellow and making ‘unclassified’ land appear with hatching rather than as blank areas on the map.

Improvements in text styling:

MasterMap original text stylingMasterMap updated text styling

Text labels have been updated to emphasise building names and reduce the size of the labels for named urban areas.

Updated rural styling:

MasterMap original rural stylingMasterMap updated rural styling

Styling in rural areas with mixed land use is a challenge as there are multiple types which need to be conveyed to the user. We have increased the number of shades of green and improved the symbol spacing and placement in order to improve the appearance of these areas. Additionally we have changed the fill colour for tracks allowing them to be more easily distinguished from paved roads.

Updated foreshore styling:

MasterMap original foreshore stylingMasterMap updated foreshore styling

Foreshore areas now display using the yellow ‘sand’ colour, making them far easier to visualise.

We hope you like the new style, however the original style can still be accessed from the Basemap menu in OS Roam:

OS Open Rivers (beta)

A number of datasets have been updated in June 2016, all in the Digimap Ordnance Survey Collection. As well as updates to the 1:25,000 and 1:50,000 Colour Raster products (which are the digital versions of the ever popular Explorer and Landranger paper map series), this month we have also updated the relatively new OS Open Rivers dataset, an image of the full network is shown on the right hand side. This is the first update to the dataset which was first released in March 2015. Users should note that this dataset is still a Beta version, so changes to the specification and/or delivery method are still possible.

We have recently added detailed, large scale, contemporary mapping to Ancient Roam allowing users to compare side by side historic mapping with detailed modern mapping.

Large Scale Contemporary Mapping in Ancient Roam

The detailed modern mapping is visible at all zoom levels in both the 1-up and 2-up views. The most detailed mapping uses the new OS OpenMap – Local product, which is the most detailed Open Data product available from Ordnance Survey and can be downloaded through the Digimap Ordnance Survey collection. We further enhanced the most detailed mapping to include the additional features from OS VectorMap District:

  • Contours
  • Spot heights
  • Medical centres
  • Police stations
  • Heritage sites
  • Places of worship

The other products we have added are OS StreetView and OS VectorMap District Raster to provide a comprehensive set of contemporary map data suitable for all zoom levels in Ancient Roam.

We hope you find the new data useful, if you have any questions about the updates or Digimap please contact us:

As many of you may be aware, the number of users of the Digimap service using CAD systems has increased considerably over the years. As this user base has grown we have endeavoured to make the data we provide as easy to use as possible in these systems. As part of this effort to continually improve the service we offer, we have made some considerable enhancements to the products we offer for use in CAD systems.

Part of the problem is that there is a proliferation of systems in use under the general banner of ‘CAD’ systems, including AutoCAD, Revit, Rhinoceros, Vectorworks to name a few. A common factor between these systems is that they can accept vector data in DWG format, however, the way that DWG data is handled can vary between systems.

A number of our products in DWG format were loading into CAD systems but some were not correctly spatially referenced. This meant that although the data looked fine and worked perfectly well on its own, but it was difficult to overlay or integrate it with other datasets. We have now fixed this issue, so that it is possible to overlay common products together much more easily.

To accompany the DWG map data we also provide Digital Terrain Model (DTM) data to allow you to create a landsurface to loacte buildings and infrastructure on. In the past we only provided the OS Terrain 5 DTM in a format that was not so easily used in some CAD systems. To remedy this, we are now delivering OS Terrain 5 DTM in the XYZ format that can be used in most CAD systems.

These are the Changes we have made:

  1. All data available as DWG should overlay correctly where appropriate in AutoCAD Map 3D, AutoCAD, AutoCAD Civil, Revit and Rhinoceros.
  2. All data has the correct Spatial Reference (British National Grid) and Units (metres).
  3. OS Terrain 5 Contours are available as 3D Polyline data which is suitable for creating surfaces in Revit and Rhinoceros 5.
  4. OS Terrain 5 DTM is available in an XYZ format which can be used to create surfaces in AutoCAD and Rhinoceros 5.
  5. OS MasterMap Sites Layer is now available in DWG.

We have updated our help pages in line with these changes and recommend that you consult the AutoCAD FAQ page which has further details for how you can load Digimap data in to common CAD packages.

We hope our CAD users find these changes useful but if you have any questions about using Digimap data in a CAD system please let us know. Similarly if you can provide us with any information about using Digimap data in a CAD system we would be very pleased to hear from you.

VectorMap Local Raster

Latest version of OS VectorMap Local Raster

A number of datasets in the Ordnance Survey Collection have been updated in May this year. We’ve also made a number of improvements to some of the datasets that are popular for 3D modelling which will hopefully make it easier to use these datasets in CAD applications. The main changes are:

  • OS MasterMap Sites Layer now available in DWG and ESRI Shapefile format (previously it was only available in GML)
  • OS Terrain 5 DTM is now available in XYZ format for use in CAD applications
  • OS Terrain 5 Contours in DWG format are now provided as as 3D contours with the height of each feature set to the correct contour height

The data format help page has been updated to reflect these changes and is a good place to go if you are interested to see which datasets are available in a specific format.

The dataset updates are detailed in the tables below for OS Data Download and OS Roam:

OS Data Download:
