Evaluation of IOF events maps
World Cup, European Orienteering Championships, Otepää, Estonia; 7-13 May 2006


Maps


Summary:
The mapping seems to be of high quality, and the level of generalisation seems to be appropriate in general.
Most serious deviations: 4-colour printing and lack of ISSOM compliance (see below).


Printing (all maps):

4-colour offset printing (not recommended for IOF events).
Overprinting effect seems to be implemented (good!).
Slight colour alignment problem (cyan-magenta).
Colours:
Black: Perfect
Blue: OK (even marshes look OK).
Green: A bit too blueish, vertical stripe rendering OK.
Brown: Contours are a bit fuzzy due to white spots appearing inside the lines, particularly on the 1:15000 maps.
Yellow: OK (except 402 gets a bit fuzzy)

The printing method has lead to poorer legibility of the maps, particularly the contours get fuzzy. Due to the small amount of fine contour detail, the maps are not totally unacceptable for this kind of terrain type, but the result would have been much better with spot colour offset printed maps.

Generalisation (ISOM):

Form lines: Mostly OK, but some areas with excessive use (effectively 2.5 meter contour interval in some areas of the middle final)

404: some too small areas mapped in the Long Qualification and the Long Final

Built-up areas seem to be overmapped (green and black special features), for instance in the middle qualification.

Symbol 404: should be 70% yellow (on the maps it seems to be the same as 403 - 50%).

ISSOM:
Contours are not visible where they go through buildings.
According to the ISSOM, they shall be!

Too much detail (fences, small buildings, hedges, builder fields, walls, ...) within buildings and forbidden areas.

No index contours in the final (except for a very short section close to control 3 in the mens course).

Should have used a darker brown in the forest for 506.1 and 529 in the final.

1:5000 would have been a better scale for these maps.

Too much use of form lines in the final.

A darker grey should have been used for the buildings in these types of terrain, to give a better contrast between buildings and runnable areas.
