FOSS4G is the annual global event of free and open source geographic technologies and open geospatial data hosted by OSGeo. In 2026 it took place in Hiroshima, Japan.
QGIS Web Client (QWC) - project status and new developments
The QGIS Web Client (QWC) provides publication of QGIS projects on the web with the same look and feel as QGIS Desktop, thanks to QGIS Server. The environment consists of a modern web application written in JavaScript using ReactJS and OpenLayers, and the qwc-services, an ecosystem of server-side Python/Flask microservices that can be used, for example, to manage user rights and edit geospatial data within the web application. This presentation gives a short introduction to the QWC project and presents new developments, e.g. the 3D view, which was developed using THREE.JS and Giro3D.
Interactive web mapping with Equal Earth projection
Most of today’s web maps are using the Web Mercator projection. A major issue of Web Mercator is the distortion of area sizes far from the equator.
In 2018 Bojan Šavrič, Tom Patterson and Bernhard Jenny published their work on the Equal Earth map projection, an equal-area projection for world maps. There is good support for it in many mapping libraries and tools and cartographers use this projection regularly for world maps.
This talk shows how to use the Equal Earth map projection for web mapping with different kind of data sources. It shows what can be already done with current technoolgy and discusses remaining obstacles.
