Geoman#

The Geoman plugin provides an interactive drawing and editing interface for polygons, polylines, circles, and other geometric shapes on your Folium map. It’s based on the Leaflet-Geoman library.

Advantages over Draw Plugin#

Geoman is a more recent and actively maintained alternative to the Draw plugin, offering several key advantages:

  • Advanced Shape Features: Supports drawing shapes with holes inside them, which is not available in the Draw plugin

  • Enhanced Editing Capabilities: Includes cutting, rotating, scaling, and snapping functionality for precise geometry editing

  • Professional Add-ons: Offers paid extensions with advanced functionality for complex GIS applications
