Query data using a time extent.
This workflow can be used to return records that are between a specified start and end date. For example, records of Canada goose sightings over time could be queried to only show sightings during the winter migration time period.
Run the sample, and a subset of records will be displayed on the map.
- An instance of
ServiceFeatureTable
is created by passing a URL to the REST endpoint of a time-enabled service. Time-enabled services will have TimeInfo defined in the service description. This information is specified in ArcMap or ArcGIS Pro prior to publishing the service. - The feature request mode of the
ServiceFeatureTable
is set toManualCache
, so that the developer can control how and when the feature table is populated with data. - A
FeatureLayer
is created by passing in the instance of theServiceFeatureTable
. - A
TimeExtent
object is created by specifying start and end date/time objects. - A
QueryParmaters
object is created with theTimeExtent
. ServiceFeatureTable.PopulateFromService
is executed by passing in theQueryParameters
.- The feature table is populated with data that matches the provided query.
