Overlapping Polygons

the Polygon-Overlap-Calculator

The Polygon-Overlap-Calculator program calculates the area of two (convex)
polygons as well as their overlap.

Convex means : any angle of the polygon is less than 180 degrees.

The number of angles may vary from 3 to 12.

Below is a reduced image of the program at work: the options of the Polgon-Overlap-Calculator are Freeware
The Polygon-Overlap-Calculator is freeware and may be used, copied and distributed without restriction.

Application
The Polygon-Overlap-Calculator may, beside calculation of areas, be used to match geographic images
such as maps and air photographs with coordinates on earth.

supplementary Information
The Polygon-Overlap-Calculator is written in the Delphi programming language.

Ordering documentation of Source code and Algorithm
All tables and procedures used for the calculations are neatly arranged in one unit.
A step-by-step approach is used : procedures process tables to produce new tables on the way to
the final result.
The sourcecode of this unit , with all data structures, variables and procedures can be ordered,
together with a detailed description of the algorithm.
