Gleo is a nascent javascript WebGL mapping library. It aims to find a niche alongside Leaflet, OpenLayers, MapLibre and Deck.gl. It was first introduced at FOSS4G 2022.
This workshop/tutorial will start with the simplest examples of how to embed a Gleo map in a webpage, then go through different available cartographic symbols and data loaders/symbolizers, and end with a deep dive into how the data is stored in WebGL data structures in the GPU.
Iván has been a web developer and FLOSS advocate since the early 2000s; then he bought a GPS receiver and got involved in OpenStreetMap and OSGeo. He’s worked with nautical charts, indoor positioning, USB microcontrollers, LibreOffice, multispectral rasters, all of it with unhealthy amounts of Javascript.
