colours. PR trails are less difficult and they have their own symbol set. We
propose using the same symbols as the terrain ones to mark the signposted
footpath on the map (cf. figure 5 ). Lastly, these GR, GRP and PR paths are
emphasized graphically because of their trail continuity: the signposted
footpath trails visibly overlaps road lines and all other cartographical
objects (cf. figure 6 ) .
3.2.2 For road cyclists
In this section, some aspects specific to road cyclists are described and
figure 9 presents the result map.
3.2.2.1 Data selection
Scale suitable for road cyclist
Road cyclists cover longer distances than the other groups. That is why
they prefer to use 1:50 000 maps. This scale permits global visualization of
their marked path. Therefore, generalized data of the same area has been
used for this group.
Points of interest
New specific data has been added to the traditional point information in
order to meet road cyclists' expectations i.e. the location of bike repairers.
Moreover, three relevant kinds of points of interest have been highlighted
in compliance with road cyclists' expectations: accommodation locations,
catering locations and panoramic view locations. These four themes form
relevant contextual information for road cyclists. Indeed, their correspond-
ing symbols must be seen at the first reading level.
