Add example of integration with Quick Map Services

[drnextgis]

Quick Map Services (QMS) is an open catalog of geodata sources since 2016 with over 1500 services (700+ are XYZ), more details here. It also provides REST API to consume data from it. I think it would be useful to have an example of integration between xyzservice and QMS. Something like this might be added to the documentation:

import folium
import requests
from xyzservices.lib import TileProvider

QMS_API = "https://qms.nextgis.com/api/v1/geoservices"

def get_service_details(service_name):
    def get_service_id(service_name):
        services = requests.get(f"{QMS_API}/?search={service_name}&type=tms&epsg=3857&limit=1")
        services = services.json()
        if services["results"]:
            return services["results"][0]["id"]
    service_id = get_service_id(service_name)
    service_details = requests.get(f"{QMS_API}/{service_id}")
    return service_details.json()

service_details = get_service_details("OpenTopoMap")

tiles = TileProvider(
    name=service_details["name"],
    url=service_details["url"],
    attribution=service_details["copyright_text"]
)

folium.Map(
    location=[53.4108, -2.9358],
    tiles=tiles.build_url(),
    attr=tiles.attribution,
)

It also might be used as a solution for #63:

service_details = get_service_details("Google Satellite")

google = TileProvider(
    name=service_details["name"],
    url=service_details["url"],
    attribution="dummy"
)

folium.Map(
    location=[53.4108, -2.9358],
    tiles=google.build_url(),
    attr=google.attribution,
)

@drnextgis this is great!

I would even be keen to turn it into a built-in method, something like TileProvider.from_qms(name). Would you like to add that? (if not, no problem, I can have a look at that at some point)?

Cool!
They have a {switch:a,b,c,d} syntax for {s} (see eg https://qms.nextgis.com/geoservices/567/), which is probably something we need to add support for.

[martinfleis]

Good catch. I guess we should replace {switch:a,b,c,d} with {s} and store "abcd" in our "subdomains"under the hood infrom_qms`. Then we don't have to add specific support for this syntax elsewhere.

Leafmap now has an interactive GUI for searching and loading basemaps from xyzservices and QMS. See opengeos/leafmap#93

Here is an interactive streamlit app for searching and loading basemaps xyzservices and QMS.
