Polygon Overlap Calculator 


Introduction
The PolygonOverlapCalculator program calculates the area of two (convex) polygons and 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 PolgonOverlapCalculator are
 number of angles selectable from 3 to 12
 calculate area of polygons and also their overlap
 shape of polygon changeable by mouse or by keyboard
 polygons can be shifted (by mouse) in the coordinate system
 changeable scale and position of coordinate system
 images can be copied to clipboard or file
 save coordinates of polygons, together with settings, to file
 open files to load previously saved polygons and settings
 print polygons, together with coordinates information
 InLine help
 no installation procedure, simply copy "overlap.exe" to a map of choice.
Freeware
The PolygonOverlapCalculator is freeware and may be used, copied and distributed without restriction.
Application
The PolygonOverlapCalculator may, beside calculation of areas, be used to match geographic images
such as maps and air photographs with earth coordinates.
