Polygon Overlap Calculator |  |
 |
Introduction
The Polygon-Overlap-Calculator 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:
 |
-
- 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
- In-Line help
- no installation procedure, simply copy "overlap.exe" to a map of choice.
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 earth coordinates.
Supplementary Information
The Polygon-Overlap-Calculator is written in Delphi-7.
