1:25 000 Scale Colour Raster support

Yes, it is possible to order user defined areas by:

• 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.

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.

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.

Please note that georeferencing is not required when using the 1:25 000 Scale Colour Raster GeoTIFF file format as the tiles have already been embedded with georeferencing information. 

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.

As part of a modernisation process, we ran a competition with the BBC's The One Show, when the general public sent in designs to replace the exisiting symbols. The winning symbols will start appearing as tiles are revised and supplied in normal change-only update refreshes.
