User LoginPolygon Drawer
Polygon Drawer is an interactive map tool that lets you draw a custom polygon by clicking directly on the map. Each point you create becomes a draggable corner, allowing you to reshape your polygon at any time. The tool also instantly generates the polygon’s coordinates and GeoJSON output, making it ideal for GIS work, mapping projects, and location-based applications.

Draw Polygons Anywhere on Earth with Polygon Drawer
Using Polygon Drawer, you can draw any type of polygon, including triangles, squares, pentagons, hexagons, concave shapes, convex shapes, cyclic polygons, equiangular polygons, star-shaped polygons, and more, anywhere on Earth. This tool allows you to define the boundaries of a piece of land, an agricultural area, a district within a town or city, or any other geographic region.
Fun Facts About Polygons
When defining a polygon on a map, the start and end points must be the same.
Each point of a polygon has a latitude and a longitude.
Polygons can be simple, like a triangle, or very complex, such as the borders of countries or regions like Baarle-Hertog (Belgium/Netherlands).
Interesting Examples of Complex Polygons
Baarle-Hertog, Belgium & Baarle-Nassau, Netherlands: This region is famous for its extremely complicated borders. You can observe multi-polygons and nested polygons in this great example.
Campione d’Italia, Italy: It is a municipality in Lombardy, Italy, that is entirely surrounded by the canton of Ticino in Switzerland.
Lesotho: It is a country completely encircled by South Africa.
Cooch-Behar, India & Bangladesh: This district once had multiple nested exclaves, where some Indian polygons were inside Bangladeshi polygons and vice versa, making it a classic example of complex, nested geopolitical polygons.
About This Polygon Drawing Tool
This page provides an easy-to-use polygon drawing tool that supports Geojson output. It allows you to create a single custom polygon on the map, refine its shape by dragging the corners, and move the entire polygon as one piece. Whether you are preparing geographic data, outlining boundaries, or working with web mapping applications, this tool offers a fast and accessible way to generate precise polygon coordinates and GeoJSON format.
Polygon Drawing Tool is good for creating custom map boundaries, GIS experimentation and prototyping, Visualizing location-based areas.
How to Use the Polygon Drawer
- Click on the map to start drawing and add each corner of your polygon.
- Add as many points as you need—each click creates a new vertex.
- Double-click anywhere on the map to finish drawing.
- Drag the corners to reshape the polygon exactly the way you want.
- Drag the polygon itself to reposition the entire shape.
- Use the Copy Coordinates or Copy GeoJSON buttons to export your data instantly.
- Click Clear Polygon if you want to start over.
