Read more about Azure Maps Services [here](https://docs.microsoft.com/azure/azure-maps/)

[Source code](https://github.com/Azure/azure-sdk-for-python/tree/main/sdk/maps/azure-maps-render) | [API reference documentation](https://docs.microsoft.com/rest/api/maps/render) | [Product documentation](https://docs.microsoft.com/azure/azure-maps/)

## _Disclaimer_

_Azure SDK Python packages support for Python 2.7 has ended 01 January 2022. For more information and questions, please refer to <https://github.com/Azure/azure-sdk-for-python/issues/20691>_

## Getting started

### Prerequisites

- Python 3.8 or later is required to use this package.
- An [Azure subscription][azure_subscription] and an [Azure Maps account](https://docs.microsoft.com/azure/azure-maps/how-to-manage-account-keys).
- A deployed Maps Services resource. You can create the resource via [Azure Portal][azure_portal] or [Azure CLI][azure_cli].

If you use Azure CLI, replace `<resource-group-name>` and `<account-name>` of your choice, and select a proper [pricing tier](https://docs.microsoft.com/azure/azure-maps/choose-pricing-tier) based on your needs via the `<sku-name>` parameter. Please refer to [this page](https://docs.microsoft.com/cli/azure/maps/account?view=azure-cli-latest#az_maps_account_create) for more details.

```bash
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.

```bash
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][azure-key-credential].

```python
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:

```python
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.

```python
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][maps_authentication_microsoft_entra_id] using the [Azure Identity library][azure_identity].
Authentication by using Microsoft Entra ID requires some initial setup:

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

After setup, you can choose which type of [credential][azure-key-credential] from `azure.identity` to use.
As an example, [DefaultAzureCredential][default_azure_credential]
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][how_to_manage_authentication] on how to find it.

```python
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](https://pypi.org/project/aiohttp/).
See [azure-core documentation](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/core/azure-core/CLIENT_LIBRARY_DEVELOPER.md#transport) 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-attribution)
- [Get Maps Static Image](#get-maps-static-image)
- [Get Maps Tile](#get-maps-tile)
- [Get Maps Tileset](#get-maps-tileset)
- [Get Maps Copyright for World](#get-maps-copyright-for-world)

### Get Maps Attribution

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

```python
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.

```python
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.

```python
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.

```python
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.

```python
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](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/core/azure-core/README.md).

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](https://docs.python.org/3/library/logging.html) 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:

```python
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)

```
