Why TileQuery?

Built from scratch for speed, efficiency, and simplicity. No databases — just tiles.

Tile-Based Engine

Data is pre-partitioned into geographic and temporal tiles. Queries only touch the tiles they need — no full table scans.

🌍

Copernicus Data

Access NO₂ and PM2.5 air quality data from the Copernicus Atmosphere Monitoring Service. European coverage, monthly granularity.

Available Datasets

Starting with Copernicus air quality. More open datasets coming soon.

🏭

NO₂ — Nitrogen Dioxide

European air quality monitoring data from CAMS. Gridded data at 0.1° resolution, monthly averages. Ideal for environmental research, urban planning, and health studies.

🌫️

PM2.5 — Fine Particulate Matter

Particulate matter under 2.5 micrometers from CAMS. Same coverage and resolution as NO₂. Critical for air quality indices and public health monitoring.

Coming soon: Eurostat economic indicators, additional Copernicus variables (O₃, SO₂, CO), and more open data sources.
