Additional information

Colour raster in monochrome

Colour Raster is not available in monochrome. Some GIS applications let you load the colour image and choose a greyscale option from an on-screen menu. This will change the colours on an image to shades of grey (greyscale). On a true monochrome map, features would be either black or white. This wouldn’t be the best way to display 1:250 000 Scale Colour Raster.

Colour options

Palette of 256 colours
