COLOUR
The basic principle is as follows:

• white represents runnable forest,
• yellow represents open areas divided into several categories,
• green represents the density of the forest and undergrowth according to its runnability and is divided into two categories.

	401 Open land Cultivated land, fields, meadows, grassland, etc. without trees, offering easy running. If yellow coloured areas becomes dominant, a screen (75%) instead of full yellow may be used. Colour: yellow.
	402 Open land with scattered trees Meadows with scattered trees or bushes, with grass or similar ground cover offering easy running. Areas smaller than 10 mm2 at the maps scale are shown as open land (401). Individual trees may be added (418, 419, 420). If yellow coloured areas becomes dominant, a screen (75%) instead of full yellow may be used. Colour: yellow (20 lines/cm).
	403 Rough open land Heath, moorland, felled areas, newly planted areas (trees lower than ca. 1 m) or other generally open land with rough ground vegetation, heather or tall grass. Symbol 403 may be combined with symbols 407 and 409 to show reduced runnability. Colour: yellow 50% (60 lines/cm).
	404 Rough open land with scattered trees Where there are scattered trees in rough open land, areas of white (or green) should appear in the tone. Such an area may be generalised by using a regular pattern of large white dots in the yellow screen. Areas smaller than 16 mm2 in the maps scale are shown as rough open land (403). Individual trees may be added (418, 419, 420). Colour: yellow 70% (60 lines/cm), white 48.5% (14.3 lines/cm).
	405 Forest: easy running Typically open runnable forest for the particular type of terrain. If no part of the forest is runnable then no white should appear on the map. Colour: white.
	406 Forest: slow running and difficult to run An area with dense trees (low visibility) which reduces running to ca. 60-80% of normal speed. Colour: green 30% (60 lines/cm).
	408 Forest: very difficult to run, impassable An area of dense vegetation (trees or undergrowth) which is barely passable. Colour: green 60% (60 lines/cm).
	412 Orchard Land planted with fruit trees or bushes. The dot lines may be orientated to show the direction of planting. If yellow coloured areas becomes dominant, a screen (75%) instead of full yellow may be used. Colour: yellow and green 25% (12.5 lines/cm). 413 Vineyard The green lines may be orientated to show the direction of planting. If yellow coloured areas becomes dominant, a screen (75%) instead of full yellow may be used. Colour: yellow and green.
	415 Cultivated land Cultivated land which is seasonally out-of-bounds due to growing crops may be shown with a black dot screen. Colour: yellow 100%, black 5% (12.5 lines/cm).
	417 Indistinct vegetation boundary Indistinct boundaries between areas of green, yellow or white are shown without a line. The edge of the area is shown only by the change in colour or dot screen.
	418, 419, 420 Special vegetation features Symbols 418, 419 and 420 can be used for special small vegetation features. The definition of the symbol must be given in each case in the map legend. Colour: green.
