Pure Node.js tiling package.

API

• buildGeoJSONLayers(featureModel, { outDir })
• generateTiles(featureModel, { outDir, minZoom, maxZoom, generatedAt, simplify, simplifyToleranceByZoom })
• writeTileManifest(manifest, outFile)

Notes

• Tile output includes basic geometry clipping.
• Optional per-zoom geometry simplification is available (Douglas–Peucker, pure JS).
• Default simplification tolerances:
  • zoom 4-5: 0.1
  • zoom 6-7: 0.01
  • zoom 8+: 0.001
• Example:

generateTiles(featureModel, {
  outDir: "./tiles",
  minZoom: 4,
  maxZoom: 10,
  simplify: true,
  simplifyToleranceByZoom: {
    4: 0.1,
    6: 0.01,
    8: 0.001
  }
});
