Posted on by

Land Cover Map 2007 VectorWe 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.

Additional products now available in DWG format for CAD users

Posted on by

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:

BHA Attributes

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 with Building Height Attribute

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.

Boundary-Line updated with different County Boundaries

Posted on by

The latest version of Ordnance Survey’s Boundary-Line data contains two new layers, Ceremonial Counties and Historical Counties.

Ceremonial Counties

OS Boundary-Line Ceremonial CountiesThis new layer in the Boundary-Line data represents the areas of England, Scotland and Wales that are represented by a Lord Lieutenant. The Lord Lieutenant is the chief officer of the county and representative of the Crown; whenever the Queen visits an area she will be accompanied by the Lord Lieutenant.

This layer is very useful for those who want to make a map of Great Britain divided into its counties without all the complexities of Unitary Authorities, Districts and Boroughs. This is the layer to choose when making a map showing a more traditional view of Great Britain without making a historical view.

Historical Counties

OS Boundary-Line Historical CountiesThe historic counties dataset shows the county boundaries in place in 1888 in England and Wales and 1899 in Scotland. The boundaries for England and Wales were derived from mapping  from the National Archives  dating from 1890. The Scottish boundaries are derived from maps as late as 1940.

This layer is very useful for those studying this time period and when combined with the ceremonial counties and modern the most up to date boundaries gives a good picture of how fluid the boundaries are over time.

Selecting Layers in Data Download

If you have the Boundary-Line data you need already but would like to add the new layers without downloading it all again then follow this useful tip. Once you have added the product to your basket click on the arrow in the layers column to pick and choose those that you want to take. See the image below:

Selecting Layers from Data Download

You will then just receive these new layers and not all the others which you may already have or not need.

Points of Interest is a national dataset covering the whole of Great Britain and contains over 4 million different features. All features are supplied with location, functional information and addresses (where possible). Points of Interest has a three-level classification to assist customers in identifying the features or sets of features they require. This classification is explained in detail in chapter 3 of the official User Guide. The top level classification is given below:

  • Accommodation, eating and drinking
  • Commercial services
  • Attractions
  • Sport and entertainment
  • Education and health
  • Public infrastructure
  • Manufacturing and production
  • Retail
  • Transport

Please note: the copyright statement for Points of Interest is slightly different to the usual Digimap statement as the data is licensed from PointX by Ordnance Survey. The correct copyright statement that should be displayed with Points of Interest data is included below:

© Crown Copyright and Database Right 2015. Ordnance Survey (Digimap Licence). This material includes data licensed from PointX© Database Right/Copyright 2015.

The data can be found in the Boundary and Location Data section in Data Download:

Points of Interest in Data Download

The data is provided in CSV format (comma separated values). To load this in to GIS for visualisation on a map requires a couple of short steps to create a definition file so that the GIS application uses the correct data types for each field in the file. We have created instructions on how to do this in ArcGIS and QGIS:

OS Building Height Attribute now available in file geodatabase format

Posted on by
3D Building Heights in ArcGIS

© Crown Copyright and Database Right 2015. Ordnance Survey (Digimap Licence)

We are pleased to announce that users can now download OS MasterMap Building Height Attribute data in file geodatabase format. The data consists 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).

This makes the process of visualising the data in 3D much simpler for the majority of GIS users. The file geodatabase format can be read by both QGIS and ArcGIS, including the new ArcGIS Pro, without the need for any complex data processing. Making the data available in file geodatabase format removes the need for users to download building features from OS MasterMap Topography Layer and then use the JOIN function in GIS to connect the Building Height Attribute data to the buildings.

3D Buildings in ArcGIS

The data is supplied on a 5x5km grid, so you may receive multiple separate geodatabases if your area covers multiple 5km grid cells, however it is easy to merge the datasets together using common GIS functions.

We hope this makes it much easier to use the data but we welcome any feedback you may have.

New OS OpenData added to Digimap Data Download

Posted on by

Ordnance Survey’s most detailed open data product, Open Map – Local,  is now available to download from the Digimap service along with the OS Open Names gazetteer, OS Open Rivers water network and OS Open Roads road network. There are no restrictions on what the data can be used for,  it just needs to carry a simple copyright acknowledgement:

Contains OS data © Crown copyright [and database right] (year)

Sample Image of OS Open Map - LocalOpen Map – Local

This is a vector dataset best viewed at a scale of 1:10,000, with layers including buildings, roads, sites, railways, hydrology, coastline, woodland and cartographic text. The data comes in Shapefile format for easy access in the most commonly used GIS software.

The data isn’t quite as feature rich as the licensed VectorMap Local data, though it does contain some nice additions such as the ability to highlight public buildings and their grounds.

Sample Image of OS Open NamesOS Open Names

This is a gazetteer with 2.5 million entries, made up of over 870,000 named and numbered roads, nearly 44,000 settlements and over 1.6 million postcodes. This dataset is billed as the comprehensive list of Great Britain’s place names, road names and numbers and postcodes, and is certainly the most detailed gazetteer in Digimap. The data is available in CSV or GML formats.

Sample Image of OS Open RiversOS Open Rivers

This is a generalised network view of the rivers of Great Britain. The data is designed to give its users a high-level view of where the water flows across the land surface.  Though it doesn’t show the detail of the actual width or shape of the river as the topographic data it is a proper network. This means it doesn’t get interrupted by bridges or other features that prevent the topographic data from being used to “route” water through the river network. The data is available in Shapefile and GML formats.

Sample Image of OS Open RoadsOS Open Roads

Like OS Open Rivers this is a generalised network of roads. Topographic data will provide more detail about the road dimensions and real world position, however this data provides an uninterrupted network for road routing analysis. The data is available in Shapefile and GML formats.

Digimap Data Download: Products Withdrawn

Posted on by

Data Download Withdrawn CategoryOrdnance Survey will withdraw two products in 2016, the 1:10 000 Raster data and the Land-Form PROFILE data.  To remind you that these products will no longer be available from the Digimap service we are putting them in a new category in Data Download.  The Withdrawn category will contain these datasets until we have to remove them from the site, March 2016 for  the 1:10 000 Scale Raster and September 2016 for the Land-Form PROFILE contours and DTM.

10k Raster data supersededRemember that the VectorMap Local Raster data is a more detailed generally better product to use than the 1:10 000 scale raster.  If you really need the cartography of the old version, you can create a print map from Digimap Roam which styles the VectorMap Local data to look like the 1:10 000 Scale Raster. Just zoom in to the Street or Neighbourhood view levels and then use the Basemaps button at the top left f the map to change to the VML Raster 10k styling. An added advantage to doing htis is that you can add in contour lines which were never available with the old data.

Land-Form PROFILE SupersededThe Land-Form Profile data has also been superseded, you should now use the OS Terrain 5 data instead. Although it is not available in DXF format, Terrain 5 is a much improved dataset compared to the older data and it is still available in the following formats: GML, Shapefile (for the contours) and ASCII (for the DTM).

If you have any questions about the withdrawal of these datasets then please let us know:
