Waymark is a free, open-source WordPress plugin designed for creating and managing interactive maps. It allows users to create maps with multiple overlays such as markers, lines, and shapes, using a user-friendly editor. Users can import data in various formats like GPX, KML, and GeoJSON, enabling them to visualize geographical information effectively. The plugin also provides customizable options for overlays, allowing for enhanced visual distinctions and meta information.

In addition to map creation, Waymark offers robust features for displaying maps on WordPress sites, including shortcode support for easy embedding. Users can create collections of maps, manage user submissions, and even allow map exports. The plugin integrates seamlessly with WordPress, using custom post types for maps and collections, and is built on the Leaflet JavaScript library, ensuring responsive performance across devices.
