ImageTile Layer

To load tiles from XYZ tile servers like OpenStreetMap tile servers or WMTS tile servers, ImageTileProvider is used as a source of data for TileLayer.

XYZ Tile server Example

import os
from here_map_widget import Map, ImageTileProvider, TileLayer

m = Map(api_key=os.environ["LS_API_KEY"], center=[39.40, -104.08], zoom=3)

url = "https://a.tile.openstreetmap.org/{z}/{x}/{y}.png"
attribution = (
    'Map data (c) <a href="https://openstreetmap.org">OpenStreetMap</a> contributors'
)
provider = ImageTileProvider(url=url, attribution=attribution)
layer = TileLayer(provider=provider)
m.add_layer(layer)
m

WMTS Example

import os
from here_map_widget import Map, ImageTileProvider, TileLayer


m = Map(api_key=os.environ["LS_API_KEY"], center=[39.40, -104.08], zoom=3.66)

url = "https://services.arcgisonline.com/arcgis/rest/services/Demographics/USA_Population_Density/MapServer/WMTS/?layer=0&style=default&tilematrixset=EPSG%3A4326&Service=WMTS&Request=GetTile&Version=1.0.0&Format=image%2Fpng&TileMatrix={z}&TileCol={x}&TileRow={y}"
provider = ImageTileProvider(url=url)
layer = TileLayer(provider=provider)
m.add_layer(layer)
m
