Classes¶

NavdataRenderer¶

Defined in: ui/map/navdata/NavdataRenderer.ts:17

NavdataRenderer - renders the static airports + waypoints overlay from a pre-built PMTiles vector archive (OurAirports data, see script/navdata/). Source-layers: "airports", "heliports", "waypoints", "runways", plus "pavement", "taxiways" and "buildings" when built with an OSM extract. The tiles load themselves, so this only declares the source + layers once and toggles their visibility. A missing archive just produces tile-load errors that MapDisplay already suppresses.

Constructors¶

Constructor¶

new NavdataRenderer(mapDisplay, stateManager): NavdataRenderer;

Defined in: ui/map/navdata/NavdataRenderer.ts:120

Parameters¶

mapDisplay¶

MapDisplay

stateManager¶

StateManager

Returns¶

NavdataRenderer

Methods¶

minAirportRankForZoom()¶

minAirportRankForZoom(zoom): number;

Defined in: ui/map/navdata/NavdataRenderer.ts:136

Lowest airport rank that is actually revealed at the given zoom, derived from AIRPORT_IMPORTANCE_BY_ZOOM (the same thresholds that drive the importance-opacity expression). Used by NavaidSnapper so snapping only targets airports the user can currently see.

Parameters¶

zoom¶

number

Returns¶

number

initialize()¶

initialize(): void;

Defined in: ui/map/navdata/NavdataRenderer.ts:162

Returns¶

void

prepareForStyleChange()¶

prepareForStyleChange(): void;

Defined in: ui/map/navdata/NavdataRenderer.ts:700

Tear down the basemap-attached aeroway layers right before a style swap starts. The persistent 'sourcedata' listener could otherwise re-attach them to a source MapLibre is mid-way through removing (seen on slow connections as "Source ... cannot be removed while layer ... is using it"). Removing the layers upfront and pausing tryAddBasemapAeroway (via styleTransitioning) until the new style loads closes that window.

Returns¶

void

onStyleChange()¶

onStyleChange(): void;

Defined in: ui/map/navdata/NavdataRenderer.ts:754

Re-add layers after a basemap style change wipes them (mirrors the pattern used by ShapeRenderer / MapOverlay).

Returns¶

void

destroy()¶

destroy(): void;

Defined in: ui/map/navdata/NavdataRenderer.ts:762

Returns¶

void
