Draw a polygon on a map online
Outline any area - a field, a property boundary, a delivery zone or a construction site - by clicking points on an interactive map. Geisro measures the area as you go and saves it to your project. Free and 100% in your browser.
How to draw a polygon on a map
- Open the map editor and sign in for free.
- Select the polygon tool from the toolbar on the map.
- Click to place each vertex along the edge of the area you want to outline.
- Close the shape by clicking the first point again or pressing Finish.
- Read the area and adjust vertices by dragging them, then save it to a layer.
Need to fine-tune later? Every polygon stays editable - drag its vertices, change its layer colour, add custom attributes, or delete the last point while you draw.
FAQ
Can I see the area of the polygon I draw?
Yes - Geisro displays the enclosed area as you draw and in the geometry's details, so you can size a plot or zone precisely.
Can I save and edit the polygon later?
Yes. Polygons are saved to your project in colour-coded layers, and stay editable - drag vertices, recolour or add attributes any time.
