... is the quality of a user's experience when using a system:
Veloland is an example of a map I like for planning tours in switzerland. A very good map in several scales is base for a lot of supplementary information necessary for tours by velo (or canoe or train ... the user can select his interests).
1001-stadtplan-at is a site that offers maps of a lot of (but not all) cities in austria. There is no declaration, which areas are covered. The quality is ok, but for my opinion, the map is to much colored. A search function is only provided for some commercial customers, so the benefit is not better than in printed maps.
