OS OpenData products now available in GeoPackage format

Four of our OS OpenData products are now available in GeoPackage format – an open standard from the Open Geospatial Consortium.

Following positive feedback on the GeoPackage format trial, where many of you asked us for a greater choice of formats, we made a commitment to make our data more accessible, interoperable and quicker to use.

On 10 April we released these four OS OpenData products in GeoPackage format, in addition to their existing formats:

  • OS Open Greenspace
  • OS VectorMap District
  • OS Terrain 50
  • Code-Point Open

The eagle-eyed amongst you will notice that this list is longer than we originally announced. We hope to continue expanding the number of products available in additional formats. Read More


Minecraft: Creating a map of Great Britain

We recruited a number of summer interns this year and one of them, Joseph Braybook, spent his time with our Innovation Labs team.  An avid fan of the Minecraft video game, he suggested building a Minecraft world using OS OpenData products. In just two weeks Joe created a Minecraft world representing over 224,000 square kilometres of Great Britain* and now we’re making it available so you can download and explore!

Looking up Southampton Water in the Minecraft map of Great Britain

If you’re not one of Minecraft’s 33 million active users, it’s a game set in virtual 3D worlds made up of cubes of different materials. Players build shelters, make things from raw materials and fend off a variety of monsters. Minecraft worlds are often computer generated, though dedicated players have also created meticulous recreations of real and imagined environments such as Hogwarts castle.

OS OpenData product update – OS Terrain 50

At the end of March we saw Ordnance Survey’s free data portal, OS OpenData, upgraded with the release of a new version of OS VectorMap District. Today, sees another significant update to OS OpenData with the release of OS Terrain 50.

OS OpenData users and developers can now access a new fully maintained analytical height product called OS Terrain 50. The new product, which has a similar resolution to Land-Form PANORAMA, will enable users to access an advanced product with consistently maintained height content for the whole of Great Britain.

Land-Form PANORAMA was an unmaintained product and was last updated in the 1990s. The new product will give users more confidence in the currency of the data and will be supplied in additional formats, making it far more accessible.

It can be easily integrated with Vector Map District which is available through OS OpenData, or OS MasterMap Topography Layer and will be a welcome addition to the tools used for terrain analysis and 3D visualisation by a wide range of users.

Arriving as a grid file, it is expected that OS Terrain 50 will be used primarily as an analytical tool for landscape visualisation and analysis over large areas. For example interrogating the visual impact of wind turbines or high-level flood risk assessment, transport infrastructure planning, environmental impact assessment (wind farm location for example), signal propagation (radio, telephone) and security and defence planning

OS Terrain 50 is part of the new OS Terrain family; OS Terrain 5  a mid-resolution DTM, designed to be interoperable with our large-scale data will be released in the near future.

 For now, OS Terrain 50 is available through the OS OpenData portal to download now.

Please select OS Terrain 50 and chose the ‘Supply format’ as ASCII GRID AND GML (GRID) – GB and tick the box to download the files.
