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:

* Note: this is the last update to OS Locator that will be supplied by Ordnance Survey who have announced that they are retiring this product. Users are advised to use OS Open Names instead. Whilst the data will still be available to download through Digimap, these products will no longer be updated to reflect changes in the real world.

The data product updates help page is kept up to date with all dataset updates in the Ordnance Survey collection.
