infra-hex-rs

A Rust library 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

1. Fetches pipeline data By bounding box
2. Converts pipeline geometries (LineStrings) into n3gb hexagon cells at a specified zoom
3. Aggregates pipeline counts per hexagon as arrow batches
4. Exports results as GeoParquet files (optional)

Example of this library being used in a Python application:

Setup

Set your Cadent API key:

export CADENT_API_KEY=your_api_key_here
