# libgd-gis continues to grow — now with styles and more

**[RUBYLAND](https://daily.dev/sources/rubyla)** · 3 min read · 2 upvotes · 0 comments

## Summary

libgd-gis has evolved from a basic geometry renderer into a comprehensive style-aware GIS engine for Ruby. Recent additions include a YAML-based style engine for cartographic control, layered GeoJSON support with semantic classification, direct canvas access via map.image for custom graphics, and an intelligent labeling system that handles roads, rivers, and points of interest. The library now enables production of publication-quality maps entirely in Ruby, without external tools like Mapbox or QGIS, demonstrated through rendered examples of New York, Paris, Tokyo, and Paraná using OpenStreetMap data.
