Digimap dataset updates November 2016

As well as releasing the new OS MasterMap Water Network Layer earlier this month, we have also updated a number of datasets available in the Ordnance Survey collection. Most notably this month we have updated OS Open Map – Local, the most detailed OpenData product available from Ordnance Survey. OS Open Map – Local was […]

New datasets in the Ordnance Survey Collection: Highways Network and Water Network

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 […]

New MasterMap style is OS Roam

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 […]

Improvements to using Digimap data in CAD systems

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.

Digimap Dataset Updates: May 2016

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.

OS MasterMap Topography Layer now available in outline ‘plan’ style for CAD users

In April 2015 we made OS MasterMap Topography Layer data available to CAD users in DWG format. If you missed the announcement you can read all about it in this blog post. Since adding this option to Digimap we have processed over 13,000 orders for MasterMap in DWG format. Building on this we have now produced an outline ‘Plan’ style of MasterMap in DWG format which is a stripped down representation that mimics the alternative ‘Line Drawing’ style of MasterMap available in the Digimap Roam application.

The alternative ‘Plan’ style is a cut down version of the full dataset and does not include polygons, users requiring the full dataset should download the original ‘Standard’ style which includes both lines and polygons.

The style is specified in the basket window of the Data Download application using the drop-down in the ‘Theme’ column:

We hope you find this new style useful, if you have any questions or suggestions for further improvements please contact us:

A new MasterMap data layer is available to download that allows you to add an extra level of information to your maps. The Sites Layer shows boundaries for features such as schools, hospitals and other government property. The dataset currently contains the extents of over 40,000 important locations in Great Britain broken down in to seven themes, with more to be added in the future:

  • Air transport
  • Education
  • Medical care
  • Rail transport
  • Road transport
  • Water transport
  • Utility or industrial

MasterMap Sites Layer includes access points, such as pedestrian gates and driveways, and routing points allowing the data to be fully integrated with other OS products including MasterMap Topography Layer and MasterMap Integrated Transport Network (ITN) layer. Sites Layer can be used for informed decision-making and spatial analysis, enabling users to answer questions such as: ‘how much of this health centre is at risk of flooding?’.

Ordnance Survey have published clear instructions on how to import the data, which is supplied in GML3 format, in to common GIS packages in their Sites Layer Getting Started Guide.
