Rating: the rating goes from one to five stars. We tend to give higher rates to hikes that are unpopular rather than popular and offer unexpected sightseeing. We also tend to give a higher rating to hikes that include some challenging parts.
Vertigo: something we acknowledge when reading guidebooks is that the information of how a track is dangerous is often missing. Of course, we are talking about trekking, not hiking.
Ground: dividing the proportions between forest, grass, rock and urban is not an easy thing to do, so we roughly estimate those proportions.
GPS related: provided by (more and less sophisticated) GPS tools.
