What to build

Implement the hardware-accelerated 3D volumetric peat dome layer using MapLibre fill-extrusion, rendering elevated carbon domes according to calculated depth heights.

Technical specifications

  1. Target files:
    • src/components/map/layers/peat-extrusion-layer.tsx: 3D fill-extrusion layer specification.
  2. Layer configuration:
    • fill-extrusion-height: Bound to scaled height property.
    • fill-extrusion-color: Bound to color gradient property.
    • fill-extrusion-opacity: 0.85 with directional shading.

Acceptance criteria

  • Tilting camera reveals clean 3D extruded peat domes.
  • Extrusion heights strictly match underlying BBSDLP classification.
  • Renders at 60fps on WebGL.

Blocked by

  • Issue 63: [Backend] Volumetric peat depth extrusion scale calculation engine (peat-extrusion.ts).
