This repository provides a reproducible R workflow for preprocessing Brazilian flight and airport data for spatial network analysis with RGraphSpace.

Workflow

The workflow:

1. Downloads 2024 flight records with flightsbr.
2. Downloads Brazilian airport metadata.
3. Harmonizes IATA and ICAO airport codes.
4. Removes international routes.
5. Identifies active Brazilian airports.
6. Aggregates flights by origin–destination pair.
7. Converts airport and geographic data to sf objects.
8. Saves the processed objects for use in an RGraphSpace vignette.

If you are not familiar to RGraphSpace, please see the available workflows: RGraphSpace - Get Started
