go gtfsparser

A complete*, easy to use parsing library for GTFS data. Implemented in go. Accepts folders containing GTFS files and ZIPs. Feeds are validated during parsing. ID references are transformed into pointer references where appropriate.

Usage

feed := gtfsparser.NewFeed()
error := feed.Parse("sample-feed.zip")

See feed.go for exported fields.

Example

Parsing of the GTFS example feed:

import (
	"github.com/geops/gtfsparser"
	"fmt"
)

func main() {
	feed := gtfsparser.NewFeed()

	feed.Parse("sample-feed.zip")

	fmt.Printf("Done, parsed %d agencies, %d stops, %d routes, %d trips, %d fare attributes\n\n",
		len(feed.Agencies), len(feed.Stops), len(feed.Routes), len(feed.Trips), len(feed.FareAttributes))

	for k, v := range feed.Stops {
        fmt.Printf("[%s] %s (@ %f,%f)\n", k, v.Name, v.Lat, v.Lon)
    }
}

Output

Done, parsed 1 agencies, 9 stops, 5 routes, 11 trips, 2 fare attributes
