# vbb-shapes

**Shapes of lines of the [Berlin Brandenburg public transport service (VBB)](http://www.vbb.de/)**, computed from [open](https://daten.berlin.de/datensaetze/vbb-fahrplandaten-gtfs) [GTFS](https://developers.google.com/transit/gtfs/) [data](https://vbb-gtfs.jannisr.de/).

## Installing

*Warning:* This module contains JSON files with a **total size of roughly 60mb**.

```shell

npm install vbb-shapes

```

## Usage

Let's assume you read trips from [`vbb-trips`](https://github.com/derhuerst/vbb-trips). Each trip has a `shapeId` associated.

```js

const shapes = require('vbb-shapes')

shapes('1269')

.then(console.log)

```

```js

[

	[52.48607, 13.4245],

	[52.48756, 13.42648],

	// …

	[52.5135, 13.52988],

	[52.51373, 13.52003]

]

```

You can also read all shapes from a [readable stream](https://nodejs.org/api/stream.html#stream_class_stream_readable) in [object mode](https://nodejs.org/api/stream.html#stream_object_mode), emitting one shape (as shown above) at once.

```js

const allShapes = require('vbb-shapes/all')

allShapes()

.on('data', console.log)

.on('error', console.error)

```

### GeoJSON encoded result

By adding the optional param `formatAsLineString = true` you'll receive a GeoJSON encoded result set.

```js

const shapes = require('vbb-shapes')

shapes('1269', true)

.then(console.log)

```

```js

{

    "type": "FeatureCollection",

    "features": [

        {

            "type": "Feature",

            "geometry": {

                "type": "LineString",

                "coordinates": [

                    [13.4245, 52.48607],

                    [13.42648, 52.48756],

                    // …

                    [13.52988, 52.5135],

                    [13.52003, 52.51373]

                ]

            },

            "properties": {}

        }

    ]

}

```

For all shapes:

```js

const allShapes = require('vbb-shapes/all')

allShapes(true)

.on('data', console.log)

.on('error', console.error)

```
