ssim2gtfs
=========================
 !npm!David

ssim2gtfs converts IATA SSIM flight schedule data into a GTFS zip containing trips, stops, stop times and calendars.

Usage

ssim2gtfs requires node 10.x or above

ssim2gtfs is a CLI tool that can be installed via NPM:

``
npm install -g ssim2gtfs
`

It can be run by specifying the input and output files as CLI arguments:

`
ssim2gtfs flights.ssim gtfs.zip
`

Or using unix pipes:

`
cat flights.ssim | ssim2gtfs > gtfs.zip
`

Notes

The GTFS does not support many of the fields in the SSIM standard so there is a lot of information that is not retained.

- An extended route type of 1100 (air service) is used
- All timezones are converted to UTC
- Stop data is derived from ourairports.com
- Agency data is derived from openflights.org/
