Region

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Region A topographic location. Regions encompass surfaces of Objects, imaginary places, and GeographicAreas. Note that a Region is the only kind of Object which can be located at itself. Note too that Region is not a subclass of SelfConnectedObject, because some Regions, e.g. archipelagos, have parts which are not connected with one another. Relationships       Parents Object Corresponds roughly to the class of ordinary objects. Examples include normal physical objects, geographical regions, and locations of Processes, the complement of Objects in the Physical class. In a 4D ontology, an Object is something whose spatiotemporal extent is thought of as dividing into spatial parts roughly parallel to the time-axis. Children AirportStagingArea An AirportStagingArea is a designated area where equipment can be staged prior to the arrival or departure of an aircraft.[Wikipedia]   AssemblyStation An AssemblyStation is a StationaryArtifact in Manufacture (ing) where individual parts are combined or attached to the final product in a specific order.   Atmosphere Atmosphere is a Mixture of gases surrounding any celestial object that has a gravitational field strong enough to prevent the gases from escaping.   FieldRegion   FlowRegion FlowRegion is a class of things whose boundaries are relatively stable but whose constitutive material is continuously moving through the region itself and being replaced by other, similar material. Each FlowRegion is constituted by a stream of matter moving as a whole. A FlowRegion may be liquid or gaseous. A wind may be considered as a Process or as a FlowRegion, similarly an OceanCurrent or a WaterWave. The motion process associated with a FlowRegion F is denoted by (FlowFn F). Note that certain properties belong to the FlowRegion itself (e.g., mass, length, volume, temperature, and speed or velocity of the region moving as a whole), while other properties of interest belong to the Motion of its constitutive stuff (e.g., velocity, direction). The motion of a FlowRegion as a whole (e.g., JetStream moves within the atmosphere) is distinguished from the motion of the pieces of stuff constituting the FlowRegion. See FlowFn and FlowRegionFn.   GeographicArea A geographic location, generally having definite boundaries. Note that this differs from its immediate superclass Region in that a GeographicArea is a three-dimensional Region of the earth. Accordingly, all astronomical objects other than earth and all one-dimensional and two-dimensional Regions are not classed under GeographicArea.   HoleRegion A hole is an immaterial body located at the surface of an Object. Since every HoleRegion is ontologically dependent on its host (i.e., the object in which it is a hole), being a HoleRegion is defined as being a hole in something. Note that two HoleRegions may occupy the same region, or part of the same region, without sharing any parts. Any two hosts of a hole have a common proper part that entirely hosts the hole. A common host of two holes hosts all parts of the sum of those holes. Any object that includes the host of a hole is a host of that hole, unless its parts also include parts of that very hole. Overlapping holes have overlapping hosts. No hole is atomic. HoleRegions are connected with their hosts. No hole can have a proper part that is externally connected with exactly the same things as the hole itself.   HydrophilicSide The class of hydrophilic sides of lipid bilayers.   HydrophobicSide The class of hydrophobic sides of lipid bilayers.   Latitude Latitude is the class of Regions, associated with areas on the Earth's surface, which are parallels measured in plane AngularDegrees from the Equator.   LineInSpace LineInSpace is a Region.Any LineInSpace contains at least two PointInSpace (points in space). If we have two LineInSpace instances and they each have two PointInSpace in common, then they are the same line. If two LineInSpaces have the relation parallel then there does not exist any PointInSpace that is part of both lines.   Longitude Longitude is the class of Regions, associated with areas on the Earth's surface, which are meridians measured in PlaneAngleDegrees from the PrimeMeridian through GreenwichEnglandUK.   MilitaryBase A MilitaryBase is a facility directly owned and operated by or for the military or one of its branches that shelters military equipment and personnel, and facilitates training and operations.[1] A military base always provides accommodations for one or more units, but it may also be used as a command center, training ground or proving ground.[Wikipedia]   MultimodalTransitPoint MultimodalTransitPoint is facility that allows travelers to and freight to easily transition between different modes of transportation. This can include rail, road, air and water transitway.   ParkingRegion A ParkingRegion is a Region where TransportationDevice is kept temporarily   PerimeterArea A PerimeterArea is a region that extends outward from a boundary with another region, surrounding or partially surrounding it, but which is not part of that other region. See BorderFn and PerimeterAreaFn.   PlaneInSpace PlaneInSpace is a Region. It is an infite plane where any pair of infinite LineInSpaces that are in the PlaneInSpace must share a single point or be parallel and not equal.   PlayArea PlayArea refers to a Region where children engage in recreational activities   PointInSpace PointInSpace is a Region.   RealEstate Land, including all the natural resources and permanent buildings on it.   SpaceRegion The class of all Regions which are not GeographicAreas.
