A number of datasets have recently been updated in Ordnance Survey Roam, the Digimap online mapping application, bringing them up to date with the most recent versions available from Ordnance Survey. All datasets are available to view using the Roam application in the Ordnance Survey collection.
The table below lists all the datasets that have been updated and includes the OS release date:
We are pleased to announce that the 2007 Land Cover Map of Great Britain, created by the Centre for Ecology and Hydrology (CEH), is now available in vector format in the Digimap Environment Download service. The new dataset makes it easier for users to perform spatial analysis, such as proximity analysis and land use studies.
The data is available in ESRI Shapefile format, which can be read by most modern Geographic Information Systems, and is supplied on 100km x 100km tiles. Accompanying the data are ESRI Layer files which can be used to display the data using 23 classes based on the UK Biodiversity Action Plan (BAP) Broad Habitats in ESRI software.
The addition of the vector version brings the availability of the 2007 Land Cover Map in line with the 2000 Land Cover Map. A full list of formats available for the 2007 data is included below:
Vector, ESRI shapefile format
25m raster, TIFF format
1km raster , TIFF format
Further information about the Land Cover Map 2007 can be found on the CEH website.
If you have any questions about the dataset or any other part of the service then please get in touch:
We are pleased to announce the release of DWG versions of both OS Terrain™ 5 (vector) and OS MasterMap® Topography Layer Building Height Attribute, which makes their use in CAD applications much easier and quicker.
Recently we have been working to produce DWG versions of the detailed vector dataset OS Terrain™ 5 and the popular Building Height Attribute component of OS MasterMap® Topography Layer. Both these datasets have proved popular with CAD users for detailed modelling applications but until now using them has proved time-consuming as many steps were required to convert them in to a format suitable for use in CAD applications.
OS Terrain 5 Vector
OS Terrain 5 Vector is dataset consisting of contour lines with five metre vertical spacing and spot heights (point features). The dataset also includes contours for mean high and low water around coastal areas, along with labels for both spot heights and contours. OS Terrain 5 is the most detailed height dataset available from Ordnance Survey. A Digital Terrain Model (DTM) version is also available in ASCII grid format and can be downloaded through Digimap.
Building Height Attribute (BHA)
As with the other BHA datasets provided through Digimap the DWG version is supplied as a dataset of building polygons together with the building height attributes supplied by OS in the latest alpha release of their Building Height Attribute dataset (December 2014 at the time of writing). The DWG dataset is a 3D dataset which uses two of the height attributes supplied by OS to create the 3D features. The base height of buildings is set using the value of the AbsHMin attribute and the roof height is defined by the AbsH2 attribute:
All height attributes supplied by OS, as indicated in the image above, are included as XDATA which can be readily viewed in CAD applications.
Note: the DWG BHA dataset is not supplied with a terrain surface so the building features will appear to float above the surface if it is displayed without a suitable terrain surface. We recommend using either OS Terrain 5 or OS Terrain 50, both of which can be downloaded from Digimap.
The image below shows OS Terrain 5 vector overlaid with BHA in AutoCAD 2015 for the area around Edinburgh Castle. Both datasets were supplied by Digimap in DWG format and required no manipulation or processing in order to display them.
OS Terrain 5 vector and OS MasterMap BHA datasets are supplied on a 5x5km grid, so you may receive multiple multiple files if your area covers more than one 5km grid square.
We hope this makes it much easier to use the data and we welcome any feedback you may have.
A number of datasets have been updated recently bringing them up to date with the most recent versions available from Ordnance Survey. All datasets are available to download using the Digimap Data Download application in the Ordnance Survey collection.
The table below lists all the datasets that have been updated and includes the OS release date:
Of particular note at this time is that Ordnance Survey have announced the withdrawal of the 1:50 000 Scale Gazetteer and OS Locator products following the release of OS Open Names in March 2015.
The last product update for 1:50 000 Scale Gazetteer will be June 2016.
The last product update for OS Locator will be May 2016
Following these releases Ordnance Survey will no longer supply, maintain or support the use of either OS Locator or 1:50 000 Scale Gazetteer.

May has been a busy month for data updates in OS Data Download. Not only have we released Points of Interest, Urban Paths and MasterMap Sites Layer, but a number of other datasets have also been updated.
The latest version of Boundary-Line includes new datasets for Welsh Wards, Historical Counties, and Ceremonial Counties. Plus the data is now available in TAB format which is great news for MapInfo users. You can read more about these changes in this blog post.
The table below lists all the datasets that have been updated and includes the OS release date:
In January 2013 the OS MasterMap®, Boundary-Line™ and Code-Point® data products will be available from the Data Download service. We have tried to keep the changes necessary to accommodate these products to a minimum as the current interface has proved so successful (190,000 map tiles and files downloaded Nov 2012).
Here is a list of the changes and additions you will see in the interface; please note that they may still be subject to some change prior to launch.
Both Boundary-Line and MasterMap have layers so we have had to make changes to the basket:
Instead of selecting Version and Format using drop-down menus there is a new pop-up for changing both these and the layers for each of the products in your basket. You can access this pop-up by clicking on the Change link in the Options column:
We have also improved the “My Account” section which is now called “My Previous Downloads”:
Once in the interface you can access any of your past downloads and reopen them at the basket stage:
It is now much easier to update your previous downloads to the latest version, get the same data in a different format or simply reorder data you have previously taken. In addition to these functions we have incorporated the ability to make Change-Only-Updates (COUs) to MasterMap Data:
Both Boundary Download and MasterMap Download will be kept in service for a transition period but as there are so many benefits to using Data Download we hope everyone will make the switch quickly. We expect to have switched off these services by the end of April.
The 1:25,000 scale Raster mapping has been updated in Digimap Roam, Carto and Data Download. This new data is the latest release by Ordnance Survey from May 2012. There has been quite a few changes with just under a third of the country seeing updates with this release.
Some of the areas with the most changes have been in the Scottish Highlands and the main London 2012 Olympic site in East London.
It is great to see (what looks like) the mapping completed for the site, and to compare how it has taken shape over the last year. Download the maps from Data Download to view the changes for yourself.

Digimap OpenStream, EDINA’s open WMS service, has been updated with the latest version of OS Street View from the OS OpenData collection. The latest version is from May 2011 and contains change-only updates.
EDINA aims to provide the latest version of OS OpenData via the OpenStream service. This means that datasets may be updated part way through an academic year.
For more information about OpenStream and to register click on the following link:
The MasterMap data in Digimap’s MasterMap Download has undergone its April update; the new data has a currency date of January 12th 2011. The data is available to download for new orders, re-orders of previous data, and as a Change-only Update (CoU) which provides only the changes to the data since it was downloaded.
CoU and Re-orders can be accessed from the Your Account page in MasterMap Download; simply select the order you want to refresh and use the CoU or Re-order (current data) buttons below the order list.
Please note that the OS MasterMap raster data (Tiff files) in Digimap’s Data Download are only updated once a year in September. You can read about these maps in a previous blog post here: MasterMap Background Maps
VectorMap District Beta Release
VectorMap District data has now been updated from the alpha release to beta in Data Download. You can read about the differences in a previous blog post here: VectorMap District beta release
