We took Canada’s Spatial Access Measures dataset (big, clunky CSVs) → turned it into a single GeoParquet file.

Add DuckDB-WASM + deck.gl & you get
- instant queries
- smooth maps
- no backend

Public data, but actually usable.

A big group of us is headed to SatCamp this week to hike, bike & scheme with an amazing community of EO enthusiasts & experts. Will we see you there?

We built stac-map, a lightweight, map-first prototype for exploring STAC GeoParquet in your browser. Built w/ DuckDB, geoarrow, & semantic STAC search, explore STAC GeoParquet files directly in the browser.
