Additional information

Defining your own areas

You can order 1:50 000 Scale Colour Raster by user-defined areas:

It's also available covering:

• Great Britain

Colour options

Palette of 256 colours

Converting to a monochrome image

Some software 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.
