Pressure isolines layer

The PressureIsolineLayer shows the atmospheric pressure isolines in millibar (mbar) or hectopascal (hPa). Forecast for air pressure at mean sea level.

Pressure isolines layer

Example

Extends: Isolines layer

Parameters

Options to provide to the Layer constructor (PressureIsolinesLayerOptions)

Properties

options.id
default: "MapTiler Isoline Pressure"
ID of the layer
options.colorramp
ColorRamp
default: ColorRamp.builtin.PRESSURE_4
Colormap to use. Maximum range possible spans from 900hPa to 1080hPa. Default spans from 900hPa to 1080hPa
options.opacity
default: 1
Opacity of the layer in [0, 1]
options.smooth
default: true
Whether or not the colorramp must be smooth
options.lineThickness
default: 1.0
Thickness of the isoline line
options.lineColor
Color [R, G, B, A]
default: [0, 0, 0, 40]
Color of the isoline lines
options.lineColorTen
Color [R, G, B, A]
default: [0, 0, 0, 120]
Line color for pressure that are multiples of 10 (980, 990, 1000, etc.)
options.renderBlurRadius
default: 4
Integer > 0. Blurring is needed to ensure smoothly curved lines. Is used in every animation frame to get best result, but higher values can make animation slower.
options.stepForZoomLevels
Array<ZoomLevelStep>
default: [ { zoom: 0, step: 4 }, { zoom: 3, step: 2 }, { zoom: 5, step: 1 } ]
Lines densities for zoom levels.
