Class: ZarrLayer<Store, Dtype, DataT>

Defined in: packages/deck.gl-zarr/src/zarr-layer.ts:150

ZarrLayer renders a GeoZarr dataset using a tiled approach with reprojection.

The caller is responsible for supplying getTileData (which fetches and converts the zarr chunk) and renderTile (which converts the result into a RenderTileResult for the GPU). This keeps the layer agnostic about data format and rendering pipeline.
