1:25 000 Scale Colour Raster support

The data equivalent of our OS Explorer paper map series, 1:25 000 Scale Colour Raster tiles are high-quality digital maps that you can embed in your GPS device or mobile app.

Can I define my own area?

  • Specific tile identities;
  • administrative region; or
  • bounding box.

The product is also available by:

  • Great Britain
  • England
  • Scotland
  • Wales

Please note that tiles are supplied whole, rather than clipped to fit geographic areas.

Does Ordnance Survey provide a list of updated tiles?

Ordnance Survey provides a list of tiles that were updated for that release on the product Technical Information page. The product is updated every March, June, September and December.

When were my tiles last updated?

Ordnance Survey provides a list of every tile depicting the date they were last updated on the Technical Information page for the product.

Can I georeference the data file?

To locate 1:25 000 Scale Colour Raster data tiles in their correct geographic position in a GIS they need to be 'georeferenced'. Refer to the Technical Information or follow the link below about geo-referencing.

Can I convert it into a monochrome image?

It depends on which software package you are using. Some packages have a facility whereby you can load the colour image onto a computer and, using one of the command drop-down menus, select the greyscale option. This will change the colours on an image to shades of grey (greyscale). This is not the same output as monochrome where features in the file are either black or white.
