Class: RasterLayer

Defined in: packages/deck.gl-raster/src/raster-layer.ts:142

Generic deck.gl layer for rendering geospatial raster data with client-side, GPU-based reprojection and custom processing pipelines.

This is a composite layer that uses RasterReprojector to generate an adaptive mesh that accurately represents the reprojected raster, then renders it using MeshTextureLayer (a small wrapper around a deck.gl SimpleMeshLayer).

Properties​

state​

state: object

Defined in: packages/deck.gl-raster/src/raster-layer.ts:146

mesh?​

optional mesh?: object

Mesh in the exact shape SimpleMeshLayer expects.

It's important for this to be passed to MeshTextureLayer as a stable reference so props.mesh equality holds across renders. This avoids unnecessarily recreating the model.

mesh.attributes​

attributes: object

mesh.attributes.POSITION​

POSITION: object

mesh.attributes.POSITION.size​

size: number

mesh.attributes.POSITION.value​

value: Float32Array

mesh.attributes.TEXCOORD_0​

TEXCOORD_0: object

mesh.attributes.TEXCOORD_0.size​

size: number

mesh.attributes.TEXCOORD_0.value​

value: Float32Array

mesh.indices​

indices: object

mesh.indices.size​

size: number

mesh.indices.value​

value: Uint32Array

positions64Low?​

optional positions64Low?: Float32Array<ArrayBufferLike>

Low-part of positions for fp64 emulation in the shaders. mesh.attributes.POSITION carries the high part.

This needs to be passed separately from mesh because SimpleMeshLayer's normalizeGeometryAttributes whitelists only positions/colors/normals/ texCoords on the mesh attributes object — anything else is silently dropped.

reprojector?​

optional reprojector?: RasterReprojector
