The Treweler GeoJSON Addon extends the Treweler Pro plugin by adding advanced features for loading, displaying, and styling GeoJSON data on WordPress maps. It supports the primary GeoJSON geometry types, including Polygon, Point, and LineString, enabling the representation of various geographic features. GeoJSON files can be easily uploaded and managed through the WordPress admin panel, simplifying the integration of geospatial data into mapping projects.

The addon provides full customization of GeoJSON feature styling, allowing the modification of both default and hover styles to achieve the desired visual appearance. Additionally, links can be configured to open when interacting with GeoJSON features, enhancing interactivity. For a more informative experience, popups displaying GeoJSON attribute data can be configured and customized, showing relevant metadata when hovering over or clicking on specific features on the map.
