Filters are configurable elements of GeoEvent Services that filter (remove from the streaming data) GeoEvents that do not satisfy specified criteria. Filters are generally attribute filters, spatial filters, or a combination of both attribute and spatial, although GeoEvent Server product macros such as $DEFINITION_NAME, for example, enable GeoEvent filtering by properties such as the name of the GeoEvent Definition associated with the current GeoEvent.
