I developed a Python-based solution that extends QGIS routing capabilities by calculating longest paths in road networks using NetworkX and modified Dijkstra's algorithm. This approach transforms traditional shortest-path analysis into maximum distance exploration, could be applied in tourism route design and hydrological analysis.

A web-based GTFS timetable viewer that processes General Transit Feed Specification (GTFS) data entirely client-side using SvelteKit. Users can upload GTFS ZIP files and instantly visualize transit schedules in an interactive timetable format with real-time status indicators.
