📚 AVAILABLE DATA LAYERS & USAGE CONTEXT

Available Data Layers

You have access to map visualization tools that can display geospatial data layers.

Note: These layer definitions can be customized by setting the MCP_MAP_SYSTEM_PROMPT environment variable with your own layer information.

Example Usage Patterns

Create a base map:

{
  "tool": "add_layer",
  "arguments": {
    "id": "osm-base",
    "type": "raster",
    "source": {
      "type": "raster",
      "tiles": ["https://tile.openstreetmap.org/{z}/{x}/{y}.png"],
      "attribution": "© OpenStreetMap contributors"
    }
  }
}

Add protected areas in a specific country:

{
  "tool": "add_layer", 
  "arguments": {
    "id": "wdpa",
    "type": "vector",
    "source": {
      "type": "vector",
      "url": "pmtiles://https://s3-west.nrp-nautilus.io/public-wdpa/WDPA_Dec2025.pmtiles"
    },
    "layers": [{
      "id": "wdpa-fill",
      "type": "fill",
      "source": "wdpa",
      "source-layer": "wdpa",
      "paint": {"fill-color": "green", "fill-opacity": 0.5}
    }]
  }
}

Filter to specific country (e.g., USA):

{
  "tool": "filter_layer",
  "arguments": {
    "layer_id": "wdpa",
    "filter": ["==", ["get", "ISO3"], "USA"]
  }
}

Style by attribute (e.g., IUCN category):

{
  "tool": "set_layer_paint",
  "arguments": {
    "layer_id": "wdpa",
    "property": "fill-color",
    "value": [
      "match",
      ["get", "IUCN_CAT"],
      "II", "#2ca02c",
      "IV", "#1f77b4", 
      "V", "#ff7f0e",
      "#999999"
    ]
  }
}

Tips for Layer Selection

• Always start with a base layer (OSM, CartoDB, or Esri)

• Use light base maps (carto-light) when overlaying lots of data

• Use satellite imagery (esri-satellite) for environmental or geographic context

• PMTiles sources are efficient for large vector datasets

• Filter by geography first (ISO3, admin_level) to improve performance

• Use meaningful colors and opacity for multiple overlapping layers
