Geo-referencing information

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.


Does Ordnance Survey provide a Legend or symbols guide?

A legend is available to download as a PDF via the Technical Information pages for this product.
