It aims to find a niche alongside Leaflet, OpenLayers, MapLibre and Deck.gl. This library was presented at FOSS4G 2022, with an emphasis on its architectural foundations: geometry/reprojection/antimeridian handling, and object-oriented abstractions for WebGL data structures. This session provides a tour of the features developed during the last year. These include, among others: Work done as part of the OSGeo-OGC codesprints (OGC API clients, experimental symbols), Animated symbols (render loop), Symbol class decorators (ability to add more functionality to a cartographic symbol class during runtime), Flexibility of scalar field manipulation (symbols that render as a magnitude instead of a colour, then the field renders as e.g. a heatmap) Sun, 31 May 2026 02:15:48 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://video.osgeo.org https://video.osgeo.org/lazy-static/avatars/de841c88-3a57-45ac-9eff-a00237356bfc.png https://video.osgeo.org/videos/watch/a6773d39-86ba-4393-a93b-b492b81c9e7f All rights reserved, unless otherwise specified in the terms specified at https://video.osgeo.org/about and potential licenses granted by each content's rightholder.
