Quick Start

MapLibre GL JS (Default)

from anymap_ts import Map

# Create a map centered on a location
m = Map(center=[-122.4, 37.8], zoom=10)
m.add_basemap("OpenStreetMap")
m.add_draw_control()
m

Mapbox GL JS

import os
from anymap_ts import MapboxMap

# Set your Mapbox token (or use MAPBOX_TOKEN env var)
m = MapboxMap(center=[-122.4, 37.8], zoom=10)
m.add_basemap("OpenStreetMap")
m

Leaflet

from anymap_ts import LeafletMap

m = LeafletMap(center=[-122.4, 37.8], zoom=10)
m.add_basemap("OpenStreetMap")
m.add_marker(-122.4194, 37.7749, popup="San Francisco")
m

OpenLayers

from anymap_ts import OpenLayersMap

m = OpenLayersMap(center=[-122.4, 37.8], zoom=10)
m.add_basemap("OpenStreetMap")

# Add WMS layer
m.add_wms_layer(
    url="https://example.com/wms",
    layers="layer_name",
    name="WMS Layer"
)
m

DeckGL

from anymap_ts import DeckGLMap

m = DeckGLMap(center=[-122.4, 37.8], zoom=10)
m.add_basemap("CartoDB.DarkMatter")

# Add scatterplot layer
points = [{"coordinates": [-122.4, 37.8], "value": 100}]
m.add_scatterplot_layer(data=points, get_radius=100)

# Add hexagon aggregation
m.add_hexagon_layer(data=points, radius=500, extruded=True)
m

Cesium (3D Globe)

from anymap_ts import CesiumMap

# Set CESIUM_TOKEN env var for terrain/3D Tiles
m = CesiumMap(center=[-122.4, 37.8], zoom=10)
m.add_basemap("OpenStreetMap")
m.set_terrain()  # Enable Cesium World Terrain
m.fly_to(-122.4194, 37.7749, height=50000, heading=45, pitch=-45)
m

KeplerGL

from anymap_ts import KeplerGLMap
import pandas as pd

m = KeplerGLMap(center=[-122.4, 37.8], zoom=10)

# Add DataFrame data
df = pd.DataFrame({
    'latitude': [37.7749, 37.8044],
    'longitude': [-122.4194, -122.2712],
    'value': [100, 200]
})
m.add_data(df, name='points')
m

Potree (Point Clouds)

from anymap_ts import PotreeViewer

viewer = PotreeViewer(
    point_budget=1000000,
    edl_enabled=True
)
viewer.load_point_cloud("path/to/pointcloud/cloud.js", name="lidar")
viewer

Common Features

Add Vector Data

geojson = {
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "geometry": {"type": "Point", "coordinates": [-122.4, 37.8]},
            "properties": {"name": "San Francisco"}
        }
    ]
}

# Works with MapLibre, Mapbox, Leaflet, OpenLayers
m.add_vector(geojson, name="points")

# Or with GeoDataFrame (requires geopandas)
import geopandas as gpd
gdf = gpd.read_file("path/to/data.geojson")
m.add_vector(gdf, name="polygons")

Map Navigation

# Fly to location with animation
m.fly_to(-122.4, 37.8, zoom=14)

# Fit to bounds [west, south, east, north]
m.fit_bounds([-123, 37, -122, 38])

Export to HTML

# All map types support HTML export
m.to_html("map.html", title="My Map")
