Interface: MapHoverInfo

Defined in: react/contexts.ts:12

Snapshot of a feature currently hovered on the map. Coordinates are pixel offsets relative to the map canvas, so consumers can render overlays inside the same position: relative container that hosts <GeoVisCanvas>.

Properties​

featureId​

featureId: string | number

Defined in: react/contexts.ts:18

Hovered feature's id (typically geometryId from mapData).

layerId​

layerId: string

Defined in: react/contexts.ts:14

Layer id under the cursor.

point​

point: object

Defined in: react/contexts.ts:26

Pixel coordinates relative to the map canvas.

x​

x: number

y​

y: number

sourceId​

sourceId: string

Defined in: react/contexts.ts:16

Source id backing the layer (kept so consumers can re-query feature-state).

value​

value: string | number | null

Defined in: react/contexts.ts:24

feature-state.value (set by mapData); supports the same value types as MapDataRow.value (number | string | null). null when the feature has no value bound or when the bound value is a non-finite number.
