Filters are configurable elements of GeoEvent Services that filter (or remove from the streaming data) GeoEvents 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, for example, enable filtering by parameters such as the name of the GeoEvent Definition associated with the current GeoEvent.
For more information on the filtering capabilities in GeoEvent Server, see the following resources:
- Attribute filters
- Spatial filters

- Create filters using regular expressions
