Percentage of polygon intersection

[Siva ram]

Hi,

First of all thanks for creating a such useful and powerful java script library. Recently I came across one requirement based on the polygon intersection. Do JSTS library have any function to compute the percentage of polygon intersection. If not could anyone please let me know how can I achieve the same.

Thanks.

Sivaram,

1. Call getArea() on the union of your polygons. 

2. Call getArea() on the intersection of your polygons.

3. Divide the intersection area by the union area and that is your percentage of intersection.
