carbonplan / geoparquet-web

This repository houses experiments for visualizing various cloud native vector formats, with a focus on exploring options for rendering GeoParquet. The web directory contains a nextjs application visualizing building footprint data using four methods:

• a single geoparquet
• a quadkey partitioned geoparquet store
• flatgeobuf
• pmtiles

The processing folder contains recipes for how the underlying GeoParquet data was created.

We presented our findings at the 2025 Cloud Native Geo conference. Our slides can be found here.
