A set of recommended tags aimed at improving the outdoor network in Thailand, with a particular emphasis on hiking, 4WD, mountain biking, and dirt biking activities.
Derived from international best practices and the minor road classification guidelines of Thailand.
Recommended Tags
Unsigned legal access keys, such as motor_vehicle, foot, bicycle, and motorcycle, should not be used to indicate the conditions of a road or path. These access keys denote legal permissions, not physical attributes, and using them inappropriately can lead to confusion and inaccurate data.
