Web Map Specification

Temporal Renderer

Temporal renderers provide time-based rendering of features in a feature layer. It can be useful to visualize historic or real-time data such as earthquake or hurricane occurrences. You can use a temporal renderer to define how observations (regular, historic, latest) and tracks are rendered. You can also show aging of features with respect to the map's time extent.

Properties

Property Details
latestObservationRenderer Simple renderer used to symbolize point geometries for the most current observations.
observationalRenderer Simple renderer used to symbolize regular/historic observations.
trackRenderer Simple renderer used to symbolize the tracks.
type Specifies the type of renderer used.
If property is present, value of this property must be temporal
