Class: GeoTIFFTileProcessor

Defined in: src/map-provider/geotiff/utils/GeoTIFFTileProcessor.ts:71

Processes GeoTIFF tiles with triangulation-based reprojection

This class encapsulates the tile rendering logic using triangulation for efficient reprojection from arbitrary source projections to Web Mercator.

Constructors

Constructor

new GeoTIFFTileProcessor(config): GeoTIFFTileProcessor

Defined in: src/map-provider/geotiff/utils/GeoTIFFTileProcessor.ts:79

Parameters

config

GeoTIFFTileProcessorConfig

Returns

GeoTIFFTileProcessor

Methods

createGlobalTriangulation()

createGlobalTriangulation(): void

Defined in: src/map-provider/geotiff/utils/GeoTIFFTileProcessor.ts:90

Create global triangulation for the entire GeoTIFF image This is called once to avoid recreating triangulation for every tile

Returns

void

---

getElevationData()

getElevationData(params): Promise<Float32Array<ArrayBufferLike>>

Defined in: src/map-provider/geotiff/utils/GeoTIFFTileProcessor.ts:666

Get raw elevation values for a tile as Float32Array.

Returns a (tileSize+1) × (tileSize+1) float array suitable for Martini terrain mesh generation. Border pixels are backfilled for Martini compatibility. Band 0 of the GeoTIFF is used as the elevation source.

Parameters

params

tileSize

number

x

Returns

Promise<Float32Array<ArrayBufferLike>>

getGlobalTriangulation()

getGlobalTriangulation(): Triangulation

Defined in: src/map-provider/geotiff/utils/GeoTIFFTileProcessor.ts:155

Get the global triangulation (may be undefined if not created yet)

Returns

Triangulation

---

getTileData()

getTileData(params): Promise<Uint8ClampedArray<ArrayBufferLike>>

Defined in: src/map-provider/geotiff/utils/GeoTIFFTileProcessor.ts:574

Generate tile data with triangulation-based reprojection

This is the main method that orchestrates the entire tile rendering process.

Parameters

params

TileDataParams

Returns

Promise<Uint8ClampedArray<ArrayBufferLike>>
