infra-hex-rs
A Rust tool for fetching gas pipeline infrastructure data and aggregating it into H3 inspired hexagonal grids.
This uses a British National Grid implementation of hexagonal grids.
What it does
- Fetches pipeline data from Cadent's OpenDataSoft API by bounding box
- Converts pipeline geometries (LineStrings) into n3gb hexagon cells at a specified zoom
- Aggregates pipeline counts per hexagon
- Exports results as GeoParquet files (optional)
The default example fetches gas pipeline infrastructure for North London and outputs a hexagonal summary at zoom level 10.
Features
- Async parallel API fetching with rate limiting
- Efficient hex grid processing
- Apache Arrow-based in-memory processing
- GeoParquet output for spatial analysis tools like QGIS
Setup
Set your Cadent API key:
export CADENT_API_KEY=your_api_key_here
