Gleo is a nascent javascript WebGL mapping library. 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) These functionalities are a fresh approach to cartographic rendering and will provide a glimpse of the potential of Object-Oriented WebGL manipulation for cartographic rendering.
