Module org.opengis.geoapi

Package org.opengis.temporal

package org.opengis.temporal

Temporal position and duration. The current GeoAPI version contains only the minimal amount of ISO 19108 (Temporal schema) interfaces required for supporting metadata and referencing by coordinates.

Integration with other standards

This package is derived from ISO 19108:2002 (Temporal schema). But that standard overlaps with ISO 19111:2019 and with the java.time standard API. In order to provide a more harmonized API, GeoAPI omits the interfaces listed below. The column on the right side shows the closest matches in other standards, but the actual type used by GeoAPI is generally a parent type for allowing flexibility.

Mapping from omitted interfaces to their replacements

Omitted ISO 19108 type	Closest equivalence
JulianDate	Combination of DirectPosition and TemporalCRS
TM_CalDate	LocalDate
TM_CalendarEra	IsoEra
TM_Calendar	TemporalCRS with CoordinateDataType.DATE_TIME
TM_Clock	TemporalCRS with user-defined CoordinateDataType
TM_ClockTime	LocalTime
TM_CoordinateSystem	TemporalCRS with CoordinateDataType.MEASURE
TM_Coordinate	Combination of DirectPosition and TemporalCRS
TM_DateAndTime	LocalDateTime
TM_Duration	TemporalAmount
TM_IntervalLength	Duration
TM_OrdinalEra	Era
TM_OrdinalPosition	Combination of DirectPosition and TemporalCRS
TM_OrdinalReferenceSystem	TemporalCRS with CoordinateDataType.INTEGER
TM_PeriodDuration	Period
TM_ReferenceSystem	TemporalCRS
TM_TemporalPosition	Temporal

Class	Description
IndeterminatePositionException	Thrown when a temporal operation cannot be performed because a position has an indeterminate value.
IndeterminateValue	Indications that a temporal position is not precisely known.
Instant	A zero-dimensional temporal primitive that represents position in time, equivalent to a point in space.
Period	A one-dimensional temporal primitive that represent extent in time.
PeriodDuration	Effectively deprecated — use java.time.Duration instead.
TemporalPrimitive	A non-decomposed element of temporal object or topology of time.
