Poly Build
Description
This component takes a group of spatial point objects and draws a polygon or polyline in a specific sort order to represent that group of points.
This component can also be used for spatial layer development by translating a collection of GPS data into polygon or polyline objects, where a polygon is a simple bounded region, such as a state boundary, and a polyline contains multiple line segments with any number of points between its start and endpoints, such as a river or road.
