freestiler now integrates H3 to generate multi-layer hexagonal vector tiles from point data. It leverages DuckDB to perform dynamic aggregations (built-in summaries or user SQL) and was demonstrated on a 12 million US groundwater wells dataset. Mapbox controls H3 resolution by zoom so hex bins display modal categories at broader zooms and individual well locations appear at zoom 10.
freestiler (R/Python) now supports H3-based vector tiling to produce multi-layer hexagonal tilesets.
Working on H3 integration into freestiler, my R/Python vector tiling tool.
The new feature uses @duckdb internally to dynamically aggregate points into a multi-layer hexagonal tileset based on some function (summary stats, or your own custom SQL).
Shown here: the 12M US groundwater wells dataset. Hexagons are styled by modal category and H3 resolution changes by zoom level in @Mapbox, giving way to individual locations at zoom 10.
