The following is a list of common terms you'll encounter when working with temporal data.
| Term | Description |
|---|---|
Temporal layer | A layer that displays data based on the current time of the time slider. |
Temporal map | A map that contains one or more temporal layers. |
Time stamp | The time attached to a piece of data (feature, image, and so on). The time stamp can be a single instant or a time interval. |
Time instant | A single point on the timeline. |
Time extent | The period of time between two points on a timeline. |
Time extent of the time slider | The period of time represented by the time slider bar. |
Time extent of the map | The period of time visualized on the map set by the controls on the time slider. |
Temporal reference | Information about the time zone and rules for daylight saving time. Setting a temporal reference allows you to visualize datasets recorded across different time zones that may or may not have rules for daylight saving time. |
Live mode | A display option associated with data that receives continuous updates outside the application. Setting time properties on layers that receive a live feed enables Live Mode on the time slider to automatically progress the map's time extent with your system clock. |
