Zip Importer ​

Zip importer is the microservice that imports GTFS from local GTFS zip file.

Uploading GTFS ​

The GTFS uploaded needs to be in the classical gtfs form, an example is shown on the next picture. This kind of GTFS file is often downloaded from a transport autority website. You can upload as much GTFS zip file as you want to create your public transport network.

You will also have to choose a date inside the date range of the GTFS. This range is displayed in the from and to columns. A selected date is preset but can be changed.

Once all the GTFS have been uploaded, and the date and time set for each of them you can click on convert in order to convert the GTFS to Quetzal's own public transport format.

Web Importer ​

Web Importer is the microservice that imports GTFS from an online repository : https://database.mobilitydata.org/. The public transport network that will be imported will be determined using a polygon.

Polygon ​

The preset polygon is a rectangle that varies in size depending on the level of zoom. If a polygon more specific is needed an option can be choose, for that we need to click on the icon shown on the next picture.

Once it is done, it is possible to move the differents nodes of the polygon by dragging them. It is also possible to add new nodes by left-clicking. The nodes can also be deleted by right-clicking on them.

It is also possible to choose to use another polygon by importing a GeoJSON file projected in EPSG 4326 (the geometry must be a polygon), for that you need to click on the icon shown in the next picture.
