# Project GNSS positions onto railway network
results = project_gnss(
    gnss_file="positions.csv",
    gnss_crs="EPSG:4326",
    network_file="network.geojson",
    network_crs="EPSG:4326",
    target_crs="EPSG:31370",  # Belgian Lambert 72
    config=ProjectionConfig()
)

for result in results:
    print(f"Position at {result.measure_meters}m on {result.netelement_id}")
