Getting started

Prerequisites

• Python 3.8 or later is required to use this package.
• An Azure subscription and an Azure Maps account.
• A deployed Maps Services resource. You can create the resource via Azure Portal or Azure CLI.

If you use Azure CLI, replace <resource-group-name> and <account-name> of your choice, and select a proper pricing tier based on your needs via the <sku-name> parameter. Please refer to this page for more details.

az maps account create --resource-group <resource-group-name> --account-name <account-name> --sku <sku-name>

Install the package

Install the Azure Maps Service Render SDK.

pip install azure-maps-render

Create and Authenticate the MapsRenderClient

To create a client object to access the Azure Maps Render API, you will need a credential object. Azure Maps Render client also support three ways to authenticate.

1. Authenticate with a Subscription Key Credential

You can authenticate with your Azure Maps Subscription Key. Once the Azure Maps Subscription Key is created, set the value of the key as environment variable: AZURE_SUBSCRIPTION_KEY. Then pass an AZURE_SUBSCRIPTION_KEY as the credential parameter into an instance of AzureKeyCredential.

from azure.core.credentials import AzureKeyCredential
from azure.maps.render import MapsRenderClient

credential = AzureKeyCredential(os.environ.get("AZURE_SUBSCRIPTION_KEY"))

render_client = MapsRenderClient(
    credential=credential,
)

2. Authenticate with a SAS Credential

Shared access signature (SAS) tokens are authentication tokens created using the JSON Web token (JWT) format and are cryptographically signed to prove authentication for an application to the Azure Maps REST API.

To authenticate with a SAS token in Python, you'll need to generate one using the azure-mgmt-maps package.

We need to tell user to install azure-mgmt-maps: pip install azure-mgmt-maps

Here's how you can generate the SAS token using the list_sas method from azure-mgmt-maps:

from azure.identity import DefaultAzureCredential
from azure.mgmt.maps import AzureMapsManagementClient

"""
# PREREQUISITES
    pip install azure-identity
    pip install azure-mgmt-maps
# USAGE
    python account_list_sas.py
    Before run the sample, please set the values of the client ID, tenant ID and client secret
    of the AAD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID,
    AZURE_CLIENT_SECRET. For more info about how to get the value, please see:
    https://docs.microsoft.com/azure/active-directory/develop/howto-create-service-principal-portal
"""


def main():
    client = AzureMapsManagementClient(
        credential=DefaultAzureCredential(),
        subscription_id="your-subscription-id",
    )

    response = client.accounts.list_sas(
        resource_group_name="myResourceGroup",
        account_name="myMapsAccount",
        maps_account_sas_parameters={
            "expiry": "2017-05-24T11:42:03.1567373Z",
            "maxRatePerSecond": 500,
            "principalId": "your-principal-id",
            "regions": ["eastus"],
            "signingKey": "primaryKey",
            "start": "2017-05-24T10:42:03.1567373Z",
        },
    )
    print(response)

Once the SAS token is created, set the value of the token as environment variable: AZURE_SAS_TOKEN. Then pass an AZURE_SAS_TOKEN as the credential parameter into an instance of AzureSasCredential.

import os

from azure.core.credentials import AzureSASCredential
from azure.maps.render import MapsRenderClient

credential = AzureSASCredential(os.environ.get("AZURE_SAS_TOKEN"))

render_client = MapsRenderClient(
    credential=credential,
)

3. Authenticate with an Microsoft Entra ID credential

You can authenticate with Microsoft Entra ID token credential using the Azure Identity library. Authentication by using Microsoft Entra ID requires some initial setup:

• Install azure-identity
• Register a new Microsoft Entra ID application
• Grant access to Azure Maps by assigning the suitable role to your service principal. Please refer to the Manage authentication page.

After setup, you can choose which type of credential from azure.identity to use. As an example, DefaultAzureCredential can be used to authenticate the client:

Next, set the values of the client ID, tenant ID, and client secret of the Microsoft Entra ID application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET

You will also need to specify the Azure Maps resource you intend to use by specifying the clientId in the client options. The Azure Maps resource client id can be found in the Authentication sections in the Azure Maps resource. Please refer to the documentation on how to find it.

from azure.maps.render import MapsRenderClient
from azure.identity import DefaultAzureCredential

credential = DefaultAzureCredential()
render_client = MapsRenderClient(
    client_id="<Azure Maps Client ID>",
    credential=credential
)

Key concepts

The Azure Maps Render client library for Python allows you to interact with each of the components through the use of a dedicated client object.

Sync Clients

MapsRenderClient is the primary client for developers using the Azure Maps Render client library for Python. Once you initialized a MapsRenderClient class, you can explore the methods on this client object to understand the different features of the Azure Maps Render service that you can access.

Async Clients

This library includes a complete async API supported on Python 3.8+. To use it, you must first install an async transport, such as aiohttp. See azure-core documentation for more information.

Async clients and credentials should be closed when they're no longer needed. These objects are async context managers and define async close methods.

Examples

The following sections provide several code snippets covering some of the most common Azure Maps Render tasks, including:

• Get Maps Attribution
• Get Maps Static Image
• Get Maps Tile
• Get Maps Tileset
• Get Maps Copyright for World

Get Maps Attribution

This request allows users to request map copyright attribution information for a section of a tileset.

from azure.core.credentials import AzureKeyCredential
from azure.maps.render import MapsRenderClient
from azure.maps.render import TilesetID

maps_render_client = MapsRenderClient(credential=AzureKeyCredential(subscription_key))

result = maps_render_client.get_map_attribution(
    tileset_id=TilesetID.MICROSOFT_BASE,
    zoom=6,
    bounds=[42.982261, 24.980233, 56.526017, 1.355233],
)

Get Maps Tile

This request will return map tiles in vector or raster formats typically to be integrated into a map control or SDK. Some example tiles that can be requested are Azure Maps road tiles, real-time Weather Radar tiles. By default, Azure Maps uses vector tiles for its web map control (Web SDK) and Android SDK.

from azure.core.credentials import AzureKeyCredential
from azure.maps.render import MapsRenderClient
from azure.maps.render import TilesetID

maps_render_client = MapsRenderClient(credential=AzureKeyCredential(subscription_key))

result = maps_render_client.get_map_tile(
    tileset_id=TilesetID.MICROSOFT_BASE,
    z=6,
    x=9,
    y=22,
    tile_size="512"
)

Get Maps Tileset

This request will give metadata for a tileset.

from azure.core.credentials import AzureKeyCredential
from azure.maps.render import MapsRenderClient
from azure.maps.render import TilesetID

maps_render_client = MapsRenderClient(credential=AzureKeyCredential(subscription_key))

result = maps_render_client.get_map_tileset(tileset_id=TilesetID.MICROSOFT_BASE)

Get Maps Static Image

This request will provide the static image service renders a user-defined, rectangular image containing a map section using a zoom level from 0 to 20. The static image service renders a user-defined, rectangular image containing a map section using a zoom level from 0 to 20. And also save the result to file as png.

from azure.maps.render import MapsRenderClient

maps_render_client = MapsRenderClient(credential=AzureKeyCredential(subscription_key))

result = maps_render_client.get_map_static_image(
    zoom=10,
    bounding_box_private=[13.228, 52.4559, 13.5794, 52.629]
)

Get Maps Copyright for World

This request will serve copyright information for Render Tile service.

from azure.core.credentials import AzureKeyCredential
from azure.maps.render import MapsRenderClient

maps_render_client = MapsRenderClient(credential=AzureKeyCredential(subscription_key))

result = maps_render_client.get_copyright_for_world()

Troubleshooting

General

Maps Render clients raise exceptions defined in Azure Core.

This list can be used for reference to catch thrown exceptions. To get the specific error code of the exception, use the error_code attribute, i.e, exception.error_code.

Logging

This library uses the standard logging library for logging. Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO level.

Detailed DEBUG level logging, including request/response bodies and unredacted headers, can be enabled on a client with the logging_enable argument:

import sys
import logging
from azure.maps.render import MapsRenderClient

# Create a logger for the 'azure.maps.render' SDK
logger = logging.getLogger('azure.maps.render')
logger.setLevel(logging.DEBUG)

# Configure a console output
handler = logging.StreamHandler(stream=sys.stdout)
logger.addHandler(handler)
