China Antique Maplibre Agent Skill

china-antique-maplibre · 中国历史古卷地图引擎

Use this skill when building or tuning antique parchment China maps in MapLibre for HyperFrames / historical video: optional raster basemap, Terrarium hillshade, optional water overlay (bring your own data), CSS antique grade, and tiered city extrusions.

When to use

• Need a production MapLibre style that reads as aged parchment over real terrain.
• Need live paint/CSS tuning before locking a HyperFrames scene.
• Need optional rivers/lakes overlay wiring (data not shipped — supply locally if needed).
• Need tiered settlements (capital / large / medium / small / pass / station / ordos).

Do not use the tuner page as the final render host.

Modes

| Mode | Purpose |

|------|---------|

| Production stack | Embed MapLibre in HyperFrames (or your app): optional satellite/raster + encoding: 'terrarium' terrain + hillshade + optional water layers + CSS filter stack + city extrusions. Drive look from exported JSON. |

| Tuner | Local HTTP page under tuner/ for interactive sliders, preset load/export, water/city toggles. |

Workflow

• Serve tuner: cd tuner && python -m http.server 8765 → http://localhost:8765/
• Tiles: default config uses EOX Sentinel-2 cloudless + Terrarium (tuner/map-tiles.config.js). Override with gitignored map-tiles.config.local.js for other sources.
• Apply default preset tuner/preset-antique-default.json (same content as tuner/presets/antique-default.json).
• Adjust satellite / hillshade / water (if you supplied data) / CSS / UI toggles until the look locks.
• Export JSON from the tuner (copy or download).
• Migrate paint + camera + CSS fields into the HyperFrames MapLibre scene (see references).
• In production: jumpTo camera (or set initial camera); wait for idle; optionally pre-cache tiles. Avoid easeTo / flyTo for recorded frames (motion blur / non-deterministic timing).
• Always set Terrarium DEM with encoding: 'terrarium'. Wrong encoding breaks hillshade/terrain.
• Final frames render from the HyperFrames / production host — not from the tuner UI.

Hard rules

• Tiles not bundled — MapLibre fetches DEM (and optional basemap) at runtime from configured URLs only.
• Only use basemap endpoints you are allowed to use — defaults are public demo tiles (EOX); swap via config when needed.
• encoding: 'terrarium' on the terrain source — mandatory.
• No easeTo / flyTo in recorded production paths; prefer jumpTo + idle.
• Do not host final render on tuner.
• Highlight water paint keys: highlightRiver / highlightWidth (UI: showHighlight). Older drafts may still say qilianRiver / showQilian — treat as aliases only when reading legacy JSON.
• Water data is not shipped — do not expect or commit tuner/assets/water-data.js. Optional local packs only; see repo root DATA-PROVENANCE.md and references/water-overlay.md.
