Wind layer

NpmLogo npm package

The WindLayer shows the atmospheric wind speed in meter per second (m/s). Forecast for speed and direction at an altitude of 10m above ground.

The WindLayer contains both a background to which is applied a color ramp and a set of moving particles, for this reason, the constructor WindLayer has more options that then other weather layers.

Wind layer

Example

Parameters

options (WindLayerOptions)?

Options to provide to the Layer constructor (WindLayerOptions)

Properties

options.id string default: "MapTiler Wind"	ID of the layer
options.colorramp ColorRamp default: `ColorRamp.builtin.VIRIDIS`	Colormap to use. Maximum range possible spans from 0m/s to 75m/s. Default spans from 0m/s to 40m/s
options.opacity number default: 1	Opacity of the layer in [0, 1]
options.smooth boolean default: true	Whether or not the colorramp must be smooth
options.color RgbaColor default: [255, 255, 255, 192]	Color of the particle. RGBA 0-255.
options.fastColor RgbaColor default: same as color	Color of the particle when moving "fast". RGBA 0-255.
options.density number default: 2	Number of particles visible per 1000 px^2
options.fadeFactor number default: 0.1	How much the particles fade over time
options.fastSpeed number	What is considered "fast" (in px/sec) for coloring purposes. Only makes sense when fastColor is used
options.maxAmount number default: 128	Quantity of particles to be created. Has to be a power of 2 and at least 4. The actual exact number will be particles * particles. Try to keep this value as low as possible to optimize performance. The number of actually visible particles is determined by density.
options.pixelRatio number default: 2 for normal displays and 1 for HiDPI displays	Use more pixels to make particles more smooth (especially when tilted)
options.refreshInterval number default: 800	Time interval (in milliseconds) how often the particles are refreshed to avoid degradation. Random 1/16 of the particles is always randomly reset
options.size number default: 1.5	Size of the particle
options.speed number default: 0.001	Speed factor of the particles
options.fastIsLarger boolean default: false	If this is `true`, the particles gets slighly larger as they become faster.

Methods

Check out the Layers method reference

pickAt (lng, lat)

Get the wind speed and direction in multiple measurement units at a given location

Parameters

lng (number) : longitude

lat (number) : latitude

Returns

Object: the value(s) as an object.

compassDirection string	Conventionnaly, wind direction is refered as where the wind comes from. For instance a north wind is a wind coming from the north. This property retrieves one of the 16 compass direction.
directionAngle number	Angular direction in dregree towards which the wind is blowing, with: 0°: true north 90°: east 180°: south 270°: west
speedFeetPerSecond number	Wind speed in ft/s (feet per second)
speedKilometersPerHour number	Wind speed in km/h (kilometer per hour)
speedKnots number	Wind speed in knots (nautical miles per hour)
speedMetersPerSecond number	Wind speed in m/s (meters per second)
speedMilesPerHour number	Wind speed in mph (miles per hour)
