"green: band for the contour" is that where you accept deviation for a particular contour or how do I have to understand this?
"It is permissible to alter the height of a contour slightly if this will improve the repre-
sentation of a feature. This deviation should not exceed 25% of the contour interval and attention must be paid to neighbouring features."
(IOF Map Committee 2000)
The green band is plus and minus 20%. Personally I do not 100% follow this rule for ex. while emphasizing forms in slopes.
