Use when adding elevation context, hillshade, or 3D terrain to a map.\nstatus: provisional\n---\n\n# MapLibre Terrain Patterns\n\nMapLibre GL JS can render terrain in several ways: **hillshade** (a 2D lighting effect from elevation data), **3D terrain** (extruded mesh that uses elevation values and camera pitch), **color-relief** (direct coloring based on elevation values), and **dynamic contour lines** (vector contours generated at runtime).[1], [7] These methods are often combined in the same map to create rich terrain visualizations.\n\nAll of these methods use a `raster-dem` source, colloquially referred to as “terrain tiles”, which encodes elevation values into PNG/WebP pixel values.[1], [3]\n\nThere are additional earth observation analysis layers traditionally derived from a DEM, like slope, aspect, and curvature.[11], [14] When these are needed, they are typically precomputed in GIS workflows and served as raster layers, rather than computed client-side in MapLibre.\n\n## When to Use This Skill\n\n- Adding hillshade, color-relief, contours, or 3D terrain to a MapLibre map\n- Choosing a `raster-dem` source and understanding encoding formats\n- Migrating from Mapbox terrain tiles to an open alternative\n- Adding dynamic contour lines from terrain data\n- Self-hosting terrain tiles in `raster-dem` format\n- Troubleshooting terrain that looks flat, inverted, or visually wrong\n\n### Differences Between DEM, `raster-dem`, and Hillshade\n\nDigital Elevation Model (DEM), `raster-dem`, and hillshade are distinct concepts that are often confused.\n\nA **DEM** is a raster where each cell stores elevation as a numeric value (for example, GeoTIFF in meters).[15], [17]\n\nMapLibre does not read those GeoTIFFs directly. Elevation is first encoded as RGB tiles (Terrain‑RGB or Terrarium), then exposed to MapLibre as a **`raster-dem` source**.[5], [6] A `raster-dem` source always represents elevation per pixel, decoded using one of the supported encodings (`\"mapbox\"` or `\"terrarium\"`).[1], [3]\n\nWhen creating a hillshade (or color‑relief, contours, or 3D terrain) in MapLibre, the key prerequisite is to choose and configure an appropriate `raster-dem` source; generating the DEM tiles yourself is computationally intensive, difficult, and usually unnecessary because high‑quality terrain services are freely or commercially available.[4], [8]\n\n### When to use precomputed rasters (instead of `raster-dem`)\n\nIn many cases it is simpler to use terrain visualizations that have already been computed in external workflows and exported as tiles. In these cases, configure your tiles as source type `raster` rather than `raster-dem`.\n\nServices like OpenTopography or Blender and standard GIS workflows (GDAL, QGIS, ArcGIS) can generate hillshade and color-relief rasters with full artistic control over lighting, texture, and color ramps.[14], [21] Slope rasters and blended “color shaded relief” products must be created directly from DEMs in these tools.[11], [20]\n\nThe advantage is that you get rich terrain visualization with minimal layer and source configuration, and performance is better because the client only draws pre-rendered tiles.[14], [22]\n\nThe limitation is that these rasters do not contain encoded elevation values (Terrain-RGB/Terrarium), so they cannot power client-side hillshade/color-relief, 3D terrain, or runtime contours in MapLibre.[3], [23]\n\nPrecomputed rasters are a good fit when you:\n\n- Only need terrain as a static background (terrain basemap, shaded relief backdrop).\n- Want consistent cartography across platforms and don’t need MapLibre to recompute hillshade or color-relief client-side.\n- Prefer to avoid the complexity of DEM encoding and `raster-dem` configuration.\n\nWhen you need MapLibre features that depend on elevation (3D terrain via `setTerrain()`, client-side hillshade or color-relief, dynamic contours), point those layers at a `raster-dem` source backed by Terrain‑RGB or Terrarium tiles—for example AWS Terrain Tiles, Mapterhorn, Stadia Terrarium, or MapTiler Terrain RGB.[1], [4]\n\n## The `raster-dem` Source and Encoding\n\nA `raster-dem` source provides elevation data encoded into PNG/WebP pixel values. MapLibre reads pixel colors and converts them to meter elevations using a formula specific to the encoding format.[1], [3]\n\n**This is the primary AI failure zone for terrain setup.** MapLibre's default encoding is `\"mapbox\"` (Mapbox Terrain‑RGB formula), but many major open and free DEM sources (for example, AWS Terrain Tiles and Mapterhorn) use the Terrarium format.[5], [6] Using the wrong encoding produces silently incorrect elevations — terrain may appear flat, inverted, or wildly exaggerated with no error in the console.\n\n| Encoding      | Formula                                       | Common sources                                   |\n| ------------- | --------------------------------------------- | ------------------------------------------------ |\n| `\"terrarium\"` | `(R * 256 + G + B / 256) - 32768`             | AWS Terrain Tiles, Mapterhorn, most open sources |\n| `\"mapbox\"`    | `(R * 256 * 256 + G * 256 + B) * 0.1 - 10000` | MapTiler terrain-rgb, Mapbox Terrain             |\n\nTerrarium and Mapbox formulas are defined by the Tilezen/Mapzen terrain pipeline and the Mapbox Terrain‑RGB specification.[5], [6]\n\n**Always verify the encoding of your DEM source before configuring the style.** The encoding is a property of the data, not a preference.\n\n```json\n{\n  \"terrain\": {\n    \"type\": \"raster-dem\",\n    \"url\": \"pmtiles://terrain.pmtiles\",\n    \"tileSize\": 512,\n    \"encoding\": \"terrarium\"\n  }\n}\n```\n\n### Open terrain tile sources\n\n| Source                                                            | Encoding  | Key required              | Notes                                                                                                                                                     |\n| ----------------------------------------------------------------- | --------- | ------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| [AWS Terrain Tiles](https://registry.opendata.aws/terrain-tiles/) | Terrarium | No                        | Original Mapzen dataset; `s3.amazonaws.com/elevation-tiles-prod/terrarium/{z}/{x}/{y}.png`; global; 256px PNG; can be slow from the browser without a CDN |\n| [Mapterhorn](https://mapterhorn.com/)                             | Terrarium | No                        | WebP PMTiles; 512px; global up to z12; NLnet-funded open source; self-host from a single file                                                             |\n| Stadia Maps Terrarium                                             | Terrarium | Yes (free tier available) | Hosted; fast CDN                                                                                                                                          |\n| MapTiler terrain-rgb                                              | Mapbox    | Yes                       | Hosted; fast CDN                                                                                                                                          |\n| `demotiles.maplibre.org`                                          | Terrarium | No                        | Used in official MapLibre examples; **not for production**                                                                                                |\n\nFor production without a key, Mapterhorn is the recommended open option.[4], [8] See [Mapterhorn](https://mapterhorn.com/) for available hosted endpoints. See [maplibre-pmtiles-patterns](../maplibre-pmtiles-patterns/SKILL.md) for extracting and self-host.\n\n## Hillshade layers\n\nA `hillshade` layer must be defined in the layers array of the map style, referencing a `raster-dem` source. It does not require `map.setTerrain()` — hillshade and 3D terrain are independent.\n\n```json\n{\n  \"id\": \"hillshade\",\n  \"type\": \"hillshade\",\n  \"source\": \"terrain\",\n  \"paint\": {\n    \"hillshade-illumination-direction\": 315,\n    \"hillshade-illumination-anchor\": \"map\",\n    \"hillshade-exaggeration\": 0.5,\n    \"hillshade-shadow-color\": \"rgba(30,40,80,0.45)\",\n    \"hillshade-highlight-color\": \"rgba(255,240,200,0.4)\",\n    \"hillshade-accent-color\": \"rgba(10,15,50,0.5)\"\n  }\n}\n```\n\n`hillshade-method` controls the shading algorithm (`standard`, `basic`, `combined`, `igor`, `multidirectional`); multidirectional hillshade can soften shadows by simulating light from multiple directions without stacking several layers.[9] Some cartographers use multiple hillshade layers with different `hillshade-illumination-direction` values to fine tune the multidirectional shading.[10], [11] This approach can impact performance.\n\nFor a basic hillshade configuration driven by a raster-dem source, see [Add a hillshade layer](https://maplibre.org/maplibre-gl-js/docs/examples/add-a-hillshade-layer/).\n\n**Color scheme for imagery basemaps:** Warm golden highlights (`rgba(255,240,200,0.4)`) and cool blue-purple shadows (`rgba(30,40,80,0.45)`) enhance imagery contrast without creating muddy grey overlays. This is the John Nelson multi-pass aesthetic adapted for single layers.[10] Use neutral grey/white highlights and dark shadows for vector basemaps where you want a cleaner look.\n\n## Dynamic Contour Lines\n\n[`maplibre-contour`](https://github.com/onthegomap/maplibre-contour) generates vector contour tiles at runtime from a `raster-dem` source. No pre-generated contour tiles needed.[7]\n\n```javascript\nimport mlcontour from 'maplibre-contour';\n\nconst demSource = new mlcontour.DemSource({\n  url: 'https://s3.amazonaws.com/elevation-tiles-prod/terrarium/{z}/{x}/{y}.png',\n  encoding: 'terrarium',\n  maxzoom: 13,\n  worker: true\n});\n\ndemSource.setupMaplibre(maplibregl);\n\nmap.on('load', () => {\n  map.addSource(\n    'contour-source',\n    demSource.contourSource({\n      thresholds: { 11: [200, 1000], 12: [100, 500], 14: [50, 200] },\n      elevationKey: 'ele',\n      levelKey: 'level',\n      contourLayer: 'contours'\n    })\n  );\n\n  map.addLayer({\n    id: 'contours',\n    type: 'line',\n    source: 'contour-source',\n    'source-layer': 'contours',\n    paint: {\n      'line-color': ['interpolate', ['linear'], ['get', 'level'], 0, '#8b6914', 1, '#5c4a00'],\n      'line-width': ['interpolate', ['linear'], ['get', 'level'], 0, 0.8, 1, 1.5]\n    }\n  });\n});\n```\n\n`maplibre-contour` uses a custom protocol handler registered via `setupMaplibre`. The `thresholds` object maps zoom level to `[minor, major]` contour intervals in meters.[7]\n\nFor a contour-lines example using `maplibre-contour` with raster-dem tiles, see [Add Contour Lines](https://maplibre.org/maplibre-gl-js/docs/examples/add-contour-lines/).\n\n## Color-relief terrain\n\nUnlike hillshade, color-relief assigns colors based on ranges of elevation values, which makes it ideal for subtly showing elevation patterns within a complex landscape visualization, or for applications where elevation differences must be legible at a glance.[14], [15]\n\nMapLibre’s `color-relief` layer type performs this client-side on terrain tiles (`raster-dem` as source).[9], [16]\n\n```json\n{\n  \"id\": \"color-relief\",\n  \"type\": \"color-relief\",\n  \"source\": \"terrain\",\n  \"paint\": {\n    \"color-relief-color\": [\n      \"interpolate\",\n      [\"elevation\"],\n      0,\n      \"#00429d\",\n      1000,\n      \"#73c1c6\",\n      2000,\n      \"#f4777f\",\n      3000,\n      \"#93003a\"\n    ]\n  }\n}\n```\n\nFor a full demo of DEM-based color-relief styling, see [Add a color relief layer](https://maplibre.org/maplibre-gl-js/docs/examples/add-a-color-relief-layer/).\n\n## 3D Terrain\n\n3D terrain extrudes the map surface based on elevation data.
