Feature c

IRI http://www.opengis.net/ont/geosparql#Feature
Is Defined By
Description

A discrete spatial phenomenon in a universe of discourse.

Example
Note

A Feature represents a uniquely identifiable phenomenon, for example a river or an apple. While such phenomena (and therefore the Features used to represent them) are bounded, their boundaries may be crisp (e.g., the declared boundaries of a state), vague (e.g., the delineation of a valley versus its neighboring mountains), and change with time (e.g., a storm front). While discrete in nature, Features may be created from continuous observations, such as an isochrone that determines the region that can be reached by ambulance within 5 minutes.

IRI http://www.opengis.net/ont/geosparql#hasBoundingBox
Is Defined By
Description

The minimum or smallest bounding or enclosing box of a given Feature.

Scope Note

The target is a Geometry that defines a rectilinear region whose edges are aligned with the axes of the coordinate reference system, which exactly contains the Feature, for example an instance of http://www.opengis.net/ont/sf#envelope.

In this case accuracy defines a zone surrounding each coordinate within wich the real positions are known to be. The accuracy value defines this zone as a distance from the coordinate(s) in all directions (e.g. a line, a circle or a sphere, depending on spatial dimension).
