smart home ontology for weather phenomena and exterior conditions
this property was known as "belongsToState" in prior versions of the ontology
The instant at which a weather report is created
Denotes the time a weather state has been observed or is forecasted for.
links a weather report to the reporting source, either an internet weather service or a local weather sensor
relation of weather states and a one-word description for the observed weather situation
Relation between weather states and the phenomena that are observed or forecasted
a specific weather state is reported for a location by a weather report.
this property describes an interval that denotes the time in the future (offset) for which the weather is reported
The relation between something and the point, or other geometrical thing in space, where it is. For example, the realtionship between a radio tower and a Point with a given lat and long. Or a relationship between a park and its outline as a closed arc of points, or a road and its location as a arc (a sequence of points). Clearly in practice there will be limit to the accuracy of any such statement, but one would expect an accuracy appropriate for the size of the object and uses such as mapping .
Wind direction
Precipitation probability
Wind speed
The WGS84 altitude of a SpatialThing (decimal meters above the local reference ellipsoid).
altitude
The WGS84 latitude of a SpatialThing (decimal degrees).
The WGS84 longitude of a SpatialThing (decimal degrees)
The dewpoint temperature is the temperature at which the air can no longer hold all of its water vapor, and some of the water vapor must condense into liquid water. The dew point is always lower than (or equal to) the air temperature.
Specifies the sun angle and thus determines if the sun is above the horizon at the time of a specific weather report
One-word description of the observed weather condition
a weather report that can be retrieved through a local sensor (e.g. weather station integrated in the smart home) or a remote internet service. Further a time division has been realized to differentiate between current, short, mid and long term forecasts. For the smart home domain, a time window of 24 hours for weather forecasts has been seen as suitable with a 24 hours forecast being classified as long-term forecast
Holds information about the origins of weather reports
Describes the actual weather reported through information from the weather source.
Uniquely identified by lat/long/alt. i.e. spaciallyIntersects(P1, P2) :- lat(P1, LAT), long(P1, LONG), alt(P1, ALT), lat(P2, LAT), long(P2, LONG), alt(P2, ALT). sameThing(P1, P2) :- type(P1, Point), type(P2, Point), spaciallyIntersects(P1, P2).
A point, typically described using a coordinate system relative to Earth, such as WGS84.
Anything with spatial extent, i.e. size, shape, or position. e.g. people, places, bowling balls, as well as abstract areas like cubes.
Granularity hour is enough for weather information
A local weather station (e.g. GIRA EIB/KNX Weather Station)
