# Map
The Map object represents the Mini Tokyo 3D map on your page. You create a Map by specifying a container and other options. Then Mini Tokyo 3D initializes the map on the page and returns your Map object.

new Map(options: Object)
# Parameters
# options (Object (opens new window))
| Name | Description |
|---|---|
options.containerstring (opens new window) | The id of the HTML element in which Mini Tokyo 3D will render the map. |
options.accessTokenstring (opens new window) | Access token for Mapbox (opens new window). If you don't specify this token, an error will occur when loading the map, so make sure to get an access token specific to your web site. |
options.secretsSecrets | An object to store the access tokens used to retrieve data. |
options.langstring (opens new window) | IETF language tag (opens new window) for the language. If not specified, the browser's default language is used. Currently 'ja', 'en', 'ko', 'zh-Hans', 'zh-Hant', 'th' and 'ne' are supported. If an unsupported language is specified, then 'en' is used. |
options.dataUrlstring (opens new window) | Mini Tokyo 3D data URL. If not specified, 'https://minitokyo3d.com/data' will be used. |
options.clockControlboolean (opens new window)default: true | If true, the date and time display will be added to the map. |
options.searchControlboolean (opens new window)default: true | If true, the search button will be added to the map. |
options.navigationControlboolean (opens new window)default: true | If true, the navigation buttons will be added to the map. |
options.fullscreenControlboolean (opens new window)default: true | If true, the fullscreen button will be added to the map. |
options.modeControlboolean (opens new window)default: true | If true, the mode switch buttons will be added to the map. |
options.configControlboolean (opens new window)default: true | If true, the configuration buttons will be added to the map. |
options.trackingModestring (opens new window)default: 'helicopter' | The initial tracking mode. 'helicopter' and 'heading' are supported. |
options.ecoModestring (opens new window)default: 'normal' | The initial eco mode. 'normal' and 'eco' are supported. |
options.centerLngLatLike (opens new window)default: [139.7670, 35.6814] | The initial geographical center point of the map. If not specified, it will default to around Tokyo station ([139.7670, 35.6814]). Note: Mini Tokyo 3D uses longitude, latitude coordinate order to match GeoJSON. |
options.zoomnumber (opens new window)default: 14 | The initial zoom level of the map. If not specified, it will default to 14. |
options.bearingnumber (opens new window)default: 0 | The initial bearing (rotation) of the map, measured in degrees counter-clockwise from north. If not specified, it will default to the true north (0). |
options.pitchnumber (opens new window)default: 60 | The initial pitch (tilt) of the map, measured in degrees away from the plane of the screen (0-85). If not specified, it will default to 60. |
options.ecoFrameRatenumber (opens new window)default: 1 | Frame rate for train and airplane animations (frames per second) when Eco Mode is on. Specify on a scale of 1 to 60. Lower values result in less smoother animations and lower CPU resource usage, thus reducing battery consumption on mobile devices. If not specified, it will default to 1. |
options.selectionstring (opens new window) | ID of the train or flight to be tracked. The train ID is a string in the form of 'odpt.Train:<operator ID>.<railway ID>.<train number>'.

options.pluginsArray (opens new window)<PluginInterface> | An array of plugins to add. Each plugin must implement PluginInterface. |
# Instance Members
# addLayer(layer)
Adds a layer to the map.
# Parameters
layer (Object (opens new window) | CustomLayerInterface (opens new window) | ThreeLayerInterface) The layer to add, conforming to either the Mapbox Style Specification's layer definition (opens new window), the CustomLayerInterface (opens new window) specification or the ThreeLayerInterface specification.
# Returns
Map: Returns itself to allow for method chaining.
# easeTo(options)
Changes any combination of center, zoom, bearing, pitch, and padding with an animated transition between old and new values. The map will retain its current values for any details not specified in options.
Note: The transition will happen instantly if the user has enabled the reduced motion accessibility feature enabled in their operating system, unless options includes essential: true.
# Parameters
options (Object (opens new window)) Options describing the destination and animation of the transition. Accepts CameraOptions (opens new window) and AnimationOptions (opens new window).
# Returns
Map: Returns itself to allow for method chaining.
# flyTo(options)
Changes any combination of center, zoom, bearing, and pitch, animating the transition along a curve that evokes flight. The animation seamlessly incorporates zooming and panning to help the user maintain her bearings even after traversing a great distance.
Note: The animation will be skipped, and this will behave equivalently to jumpTo if the user has the reduced motion accessibility feature enabled in their operating system, unless options includes essential: true.
# Parameters
options (Object (opens new window)) Options describing the destination and animation of the transition. Accepts CameraOptions (opens new window), AnimationOptions (opens new window), and the following additional options.
| Name | Description |
|---|---|
options.curvenumber (opens new window)default: 1.42 | The zooming "curve" that will occur along the flight path. A high value maximizes zooming for an exaggerated animation, while a low value minimizes zooming for an effect closer to Map#easeTo. 1.42 is the average value selected by participants in the user study discussed in van Wijk (2003) (opens new window). A value of Math.pow(6, 0.25) would be equivalent to the root mean squared average velocity. A value of 1 would produce a circular motion. |
options.minZoomnumber (opens new window) | The zero-based zoom level at the peak of the flight path. If options.curve is specified, this option is ignored. |
options.speednumber (opens new window)default: 1.2 | The average speed of the animation defined in relation to options.curve. A speed of 1.2 means that the map appears to move along the flight path by 1.2 times options.curve screenfuls every second. A screenful is the map's visible span. It does not correspond to a fixed physical distance, but varies by zoom level. |
options.screenSpeednumber (opens new window) | The average speed of the animation measured in screenfuls per second, assuming a linear timing curve. If options.speed is specified, this option is ignored. |
options.maxDurationnumber (opens new window) | The animation's maximum duration, measured in milliseconds. If duration exceeds maximum duration, it resets to 0. |
