To a field in a GeoEvent Definition can be used to identify theĬonvex Hull Creator can be configured to either replace the Otherwise, the processor will produce the smallest convex polygon that contains the GeoEvent's geometry.Ĭonvex Hull Creator requires that the field containing the.Given a simple convex polygon or envelope, this processor will produce an equivalent geometry.Given a line with two vertices, this processor will produce an equivalent line.Given a point, this processor will produce an equivalent point.Conceptually, a convex hull is the shape a rubber band would take if it were stretched around a GeoEvent's geometry. Use a Convex Hull Creator pocessor when you need to dynamically produce a polygon representing the smallest region or area enclosing a GeoEvent's geometry. Known Identifier (WKID) of the most appropriate projection.įor more information on the Buffer Creator Processor, see the Introduction to GeoEvent Extension tutorial available from GeoEvent Extension tutorials. With the GeoEvent geometries being received, use the numeric Well When specifying a projection other than the one associated A projected coordinate system, roughly centered within theĮxpected extent of the expected event geometries, should be chosen For example, point locations that received in the WGS84Ĭoordinate system cannot be buffered in that same coordinate Projection other than the one associated with the geometry beingīuffered. When computing a buffer, it is sometimes necessary to specify a Theīuffer distance is specified as a positive integer value.
Units for the processor through the ArcGIS GeoEvent Manager. GeoEvent Extension administrators can configure the
The Buffer Creator interface provides a list withĬommon linear units such as Feet, Yard, Meter, Kilometer, and The GeoEvent Extensiondoes not support buffers measured in angular units (for example, decimalĭegrees). Units and a numeric distance for the buffer. When creating a geometric buffer, you must specify the linear Or the GeoEvent Service in which the processor participates. GeoEvent Extension and deleted if changes are made to the processor The new GeoEvent Definition will be managed by the New field requires the GeoEvent Extension to create a new GeoEventĭefinition. GeoEvent's geometry with the computed buffer or place the computedīuffer into a new field. This processor can be configured to either replace the Name or a tag applied to a field within a GeoEvent Definition can This processor requires theįield containing the GeoEvent's geometry to be specified.
The Buffer Creator Processor can be used to dynamically create aīuffer around a GeoEvent's geometry. GeoEvent Extension includes the following processors: The type of processor being created is specified using the Processor drop-down arrow, as illustrated below. The name is case-sensitive and will be used to uniquely identify the processor in a GeoEvent Service. Processors are a component of a GeoEvent Service that perform specific actions on the GeoEvents, such as identification or enrichment as GeoEvents are routed from inputs to outputs.Īll processors, when created, must be assigned a name.
