Polygon

A polygon is a multi-sided geographic feature used in mapping and Geographic Information Systems (Geographic Information Systems) to represent defined areas on the Earth’s surface. It is formed by connecting a sequence of ordered vertices, where each point links to the next, and the final point closes the shape to create a bounded region.

In GIS, polygons are essential for representing real-world spatial features that cover an area rather than a single point or line. They are widely used to model land parcels, lakes, forests, agricultural fields, urban boundaries, administrative regions, and zoning areas. Each polygon can store attributes such as name, area, perimeter, land use type, or ownership information, making them valuable for spatial analysis, planning, and decision-making.

Polygons also help in measuring areas, analyzing overlaps, and understanding relationships between different geographic regions.
