Simplifier Processor

The Simplifier Processor can be used to correct a GeoEvent's associated geometry to render the geometry topologically consistent with its type. Simplify has no effect on point geometry. Multipoint geometry will snap all vertices to a grid appropriate for the geometry's spatial reference and then remove duplicate vertices. Polyline and polygon geometries with self-intersecting segments will be reconstructed with multiple paths or rings to produce a topologically correct multipart polyline or polygon.

Simplification is not the same as generalization. Simplification does remove unnecessary vertices along an otherwise topologically correct line segment or reshape a geometry to reduce detail to produce a geometry for more efficient display at small map scales. The purpose of simplification is to produce a feature that is valid for insertion into a geodatabase. Features created in an ArcGIS Desktop editing session are already topologically correct and simple. Features polled from a feature service do not require simplification before processing them in a GeoEvent Service.

The Simplifier Processor requires the GeoEvent field containing the geometry be specified. You can specify either the GeoEvent field name or a tag applied to a field within a GeoEvent Definition that identifies the geometry field.

This processor can be configured to replace the GeoEvent's geometry with the simplified geometry or place the simplified geometry into a new field. Adding a new field to a GeoEvent alters the GeoEvent's schema, which requires GeoEvent Server to create a new GeoEvent Definition. The new GeoEvent Definition will be managed by GeoEvent Server and deleted if changes are made to the processor or the GeoEvent Service in which the processor participates.
