    Properties

    layers_

    layers_: Layer[]

    Ordered thematic layer stack (bottom → top).

    activeLayerIndex_

    activeLayerIndex_: number

    Methods

    • Initial map viewport. x/y in projected coordinates, z is pixel size (map units per screen pixel — smaller = more zoomed in).

      Parameters

      • v: { x?: number; y?: number; z?: number }

      Returns this

      map.position({ x: 4800000, y: 3400000, z: 6000 })

    • Returns { x: number; y: number; z: number }

    • Returns the concrete statData key for a channel/category combination.

      Parameters

      • channel: string
      • OptionalcategoryCode: string
      • OptionalfallbackStat: string

      Returns string

    • Returns a region value through encoding lookup.

      Parameters

      • channel: string
      • regionId: string
      • OptionalcategoryCode: string
      • OptionalfallbackStat: string

      Returns string | number

    • Returns unit text through encoding lookup.

      Parameters

      • channel: string
      • OptionalcategoryCode: string
      • OptionalfallbackStat: string

      Returns string

    • Returns the time dimension value from the loaded Eurostat dataset. Useful for displaying the data period in the map title.

      Returns string

      map.onBuild(() => map.title('Population ' + map.getTime()))

    • Builds the map from scratch. Call once after initial configuration.

      Returns this

      eurostatmap.map('choropleth')
        .stat({ eurostatDatasetCode: 'demo_r_d3dens' })
        .build()
