Filipe Cordovil developed and maintained structured airspace sector datasets for the lennycolton/vatglasses-data repository, focusing on enhancing airspace modeling and management workflows. He introduced a detailed JSON artifact defining SBAZ FIR sector boundaries, attributes, altitude layers, and ownership, enabling more accurate and traceable airspace data. Filipe applied data engineering and airspace management skills to ensure the repository’s readiness for operational use. In subsequent work, he improved data quality by cleaning obsolete FIR sectors, removing outdated airport entries, and updating callsign names, leveraging data cleaning and management techniques. His contributions provided depth in both data modeling and dataset maintainability.
