Felix Sommer developed and enhanced the geoadmin/web-mapviewer, focusing on interactive map features, robust data handling, and improved user workflows. He implemented support for complex geometries like MultiPolygon and KML, stabilized 2D/3D transitions, and introduced accessibility improvements such as keyboard navigation and responsive design. Using technologies including JavaScript, Vue.js, and OpenLayers, Felix refactored core components for maintainability, integrated external data sources, and enforced code quality with tools like Stylelint. His work addressed reliability in time-enabled layers, legacy URL handling, and security for content rendering, resulting in a more stable, user-friendly, and maintainable geospatial web application.

Geospatial web-mapviewer (geoadmin/web-mapviewer) – June 2025: Delivered key features and stability improvements driving reliability and data fidelity for complex geometries and time-enabled layers. Highlights include MultiPolygon support in Map Viewer with a new KML fixture and E2E tests; stabilized print area rendering via a dedicated VectorLayer; resolved Vue 3 single root element warnings; and hardened time slider behavior for WMS layers and URL handling. These changes enhance user confidence when visualizing complex datasets, reduce maintenance burden, and improve performance and UX for time-based geospatial data.
