The recommended format
for the base maps is the following:
 |
Scale 1:5,000 or 1:10,000 |
|
|
20-m contour
lines colored 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.
|
|
 |
|
 |
Disrupted lines
and insufficient elevation labels are common weaknesses in
poorly prepared base maps. |
