¿Qué hace MapStage?

Use this skill when building or tuning a MapStage scene: map/globe projection, satellite, hypsometric relief, Mapterhorn terrain, region isolate, CSS color grade, and JSON export.

When to use

• Need a live MapStage tuner (map vs globe, satellite vs relief, isolate).
• Need to lock paint / CSS / camera, then export JSON into another host.
• 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 MapStage in your app: optional satellite/raster + Mapterhorn DEM (encoding: 'terrarium') + hillshade + OpenFreeMap vector water + CSS filter + city extrusions. Drive look from exported JSON.
Tuner	Local HTTP page under tuner/ for sliders, projection, isolate, preset load/export.

Workflow

1. Serve tuner: cd tuner && python -m http.server 8765 → http://localhost:8765/
2. Tiles: default EOX Sentinel-2 cloudless + Mapterhorn (tuner/map-tiles.config.js). Override with gitignored map-tiles.config.local.js.
3. Apply default preset tuner/preset-antique-default.json (same as tuner/presets/antique-default.json).
4. Adjust projection / satellite / relief / isolate / CSS / cities until the look locks.
5. Export JSON from the tuner (copy or download).
6. Migrate paint + camera + CSS fields into the production MapStage scene (see references).
7. In production: jumpTo camera; wait for idle; optionally pre-cache tiles. Avoid easeTo / flyTo for recorded frames.
8. Always set DEM with encoding: 'terrarium'. Wrong encoding breaks hillshade/terrain.
9. Final frames render from the production host — not from the tuner UI.

Hard rules

• Tiles not bundled — MapStage fetches DEM and 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.
• Water is the built-in OpenFreeMap / OpenMapTiles vector layers. Do not expect or commit tuner/assets/water-data.js.
