Feature

An abstraction of real-world phenomena. An ITS-domain feature (subclass of geo:Feature) used to model real-world things that have a spatial location.

NOTE: Geographic features can be defined for any geographic entity that can be defined with geospatial boundaries, such as landmarks, buildings, transport infrastructure (e.g., road, pathway, railway, bridge structures, intersections, traffic signal cabinet, traffic signal pole, waterway), jurisdictional areas (e.g., country, city), etc.
