Uso
The Output Feature Class parameter contains the input polygons with overlap removed.
If no overlap exists between the input polygons, the output feature class will be a copy of the input.
You can assign a numeric attribute from the Input Features parameter with the Weight Field parameter to influence the location of the boundary being created. The polygon with the higher value will contain more of the overlapping area when the border is defined.
Overlapping trade areas containing multiple rings of equal values can present challenges to preserve boundaries. The Define Trade Areas parameter allows you to assign a ring ID field that identifies which parts of overlapping trade areas will be dissolved together. For example, if your input features are trade areas consisting of 1-,3-, and 5-mile rings around stores, boundaries will be created for three separate areas: a boundary for 1-mile rings, a boundary for 3-mile rings, and a boundary for 5-mile rings.
The Center Line option in the Method parameter creates a border that evenly distributes the area of overlap between polygons. For example, if two polygons overlapped, this method would draw a straight line from each intersection and split the two areas in half. Center Line is the simplest method compared to the more complex Grid and Thiessen options.
The Grid option in the Method parameter removes overlap by creating a grid of parallel lines used to find a natural division between two polygons.
The Thiessen option in the Method parameter removes overlap between two or more trade areas using straight lines to divide the area of overlap. This method uses a series of geometric functions to create nonoverlapping trade areas.
