Feature c

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. |
