Filters are configurable elements of GeoEvent Services that filter (or remove from the streaming data) event records that do not satisfy specified criteria. Filters are typically attribute filters, spatial filters, or a combination of attribute and spatial, although GeoEvent Server product macros such as $DEFINITION_NAME, enable filtering by parameters such as the name of the GeoEvent Definition associated with the active event record.
For more information on the filtering capabilities in GeoEvent Server, refer to the following resources:
