The image below shows four polygons created from points located within a maximum distance of 250 kilometers from one another. The two points (outliers) located beyond the aggregation distance are not included in any polygon. A stand-alone one-to-many relationship table is created to link the ...

If a field is specified as theSort Fieldparameter value, points will be sorted in ascending order of the field. You can create polygons from input points by first checking theClose Lineparameter to create closed line features. Then use the output line feature class as input to theFeature To...

polygon:Polygon|Feature|Array<Point> - The polygon or array of points composing a polygon. centroidType(Optional):Text-Since 1.29Determines the placement of the centroid. Possible values: geometric: (default) The true centroid of the geometry. The geometric centroid for an array of points will ...
Polygons have one or more distinct parts. Each part is a sequence of points describing a closed boundary. For a single area with no holes, you can use thePolygonconstructor to create a polygon with just one part. To create a polygon with more than one part, use aPolygonBuilder. ...
