Scale 1:5,000 or 1:10,000

20-m contour lines coloured in a recurrent sequence: e.g. brown (100m), blue (120m), green (140m), purple (160m), black (180m); brown (200m), blue (220m), green (240m), purple (260m), etc.

Format of the contour lines: 1 pt., except for the "index contours" (100m, 200m, 300m, 400m, etc.), which should be 2 pt. thick. ·

40-m contours are a valid alternative. The color sequence could be the following: e.g. brown (0m), blue (40m), green (80m), purple (120m), black (160m); brown (200m), blue (240m), green (280m), purple (320m), etc. ·

Elevation labels: many, to facilitate the identification the elevation of each contour during tracing. In addition elevation labels should be placed at all hill- and mountaintops or bottoms of depressions.

Grid (10 cm = 1 km on the ground for a 1:10,000 scale model). Format: Solid line, black, 1 pt. ·

Contour line expressing the lowest elevation: to be identified with a mark, e.g. an arrow. This allows locating the first contour line to be traced and cut out.

Administrative boundaries (e.g. national boundary. Format: dashed line - black, 2 pt.) ·

Protected Area Boundary. Format: solid line - red, 2 pt. ·

Buffer Zone Boundary. Format: solid line - orange, 2 pt.
