What are deck.gl and QGIS?
deck.gl
deck.gl is an open-source WebGL framework for visualizing large geospatial datasets as map overlays. It renders millions of points, arcs, and polygons on top of self-hosted basemaps.
- WebGL data visualization
- Large dataset rendering
- Map overlay layers
- Works with any basemap
QGIS
QGIS is a professional, full-featured geographic information system for creating, editing, analyzing, and visualizing spatial data. It runs on the desktop and supports many data formats and plugins.
- Full GIS analysis toolkit
- Many data format support
- Large plugin ecosystem
- Map composer
deck.gl vs QGIS: key differences
Deck.gl is written in TypeScript, while QGIS is built with C++. Licensing differs — MIT for deck.gl versus GPL-2.0 for QGIS. Deck.gl is the lighter option, starting around 256 MB of RAM against 4,096 MB for QGIS. QGIS is the more established project (first released 2002), while deck.gl arrived in 2016.
