Traffic - Get Traffic Incident Viewport

Traffic Incident Viewport

Applies to: S0 and S1 pricing tiers.

This API returns legal and technical information for the viewport described in the request. It should be called by client applications whenever the viewport changes (for instance, through zooming, panning, going to a location, or displaying a route). The request should contain the bounding box and zoom level of the viewport whose information is needed. The return will contain map version information, as well as the current Traffic Model ID and copyright IDs. The Traffic Model ID returned by the Viewport Description is used by other APIs to retrieve last traffic information for further processing.

URI Parameters

Name In Required Type Description
format
path True

Desired format of the response. Value can be either json or xml.

subscription-key
query
  • string

One of the Azure Maps keys provided from an Azure Map Account. Refer to the subscription-key security definition.

api-version
query True
  • string

Version number of Azure Maps API. Current version is 1.0

boundingbox
query True
  • string

Bounding box of the map viewport in EPSG900913 projection. The boundingbox is represented by two value pairs describing it's corners (first pair for lower left corner and second for upper right). All values should be separated by commas (e.g., minY,minX,maxY,maxX). The maximum size of the bounding box that can be passed is dependent on the requested zoom level. The width and height cannot exceed 4092 pixels when rendered on the given zoom level.

NOTE: Bounding boxes that cross the 180° meridian require special treatment. For such boxes, the eastern maxX value will be negative, and thus less than the minX value west of the 180° meridian. To address that, the value 40075016.6855874 should be added to the true maxX value before it is passed in the request.

boundingzoom
query True
  • integer

Zoom level of the map viewport. Used to determine whether the view can be zoomed in.

overviewbox
query True
  • string

Bounding box of the overview map in EPSG900913 projection.

Used in case the overview box/mini map has different copyright data than the main map. If there is no mini map, the same coordinates as boundingBox is used.

overviewzoom
query True
  • integer

Zoom level of the overview map. If there is no mini map, use the same zoom level as boundingZoom.

copyright
query True
  • boolean

Determines what copyright information to return. When true the copyright text is returned; when false only the copyright index is returned.

Request Header

Name Required Type Description
x-ms-client-id
  • string

Specifies which account is intended for usage in conjunction with the Azure AD security model. It represents a unique ID for the Azure Maps account and can be retrieved from Azure Maps management plane Account API. To use Azure AD security in Azure Maps see the following articles for guidance.

Security

azure_auth

These are the Azure Active Directory OAuth2 Flows. When paired with Azure Role Based Access control it can be used to control access to Azure Maps REST APIs. Azure Role based access controls are used to designate access to one or more Azure Maps resource account or sub-resources. Any user, group, or service principal can be granted access via a built in role or a custom role composed of one or more permissions to Azure Maps REST APIs.

To implement scenarios we recommend viewing authentication concepts. In summary, this security definition provides a solution for modeling application(s) via objects capable of access control on specific APIs and scopes.

Note

  • This security definition requires the use of the x-ms-client-id header to indicate which Azure Maps resource the application is requesting access to. This can be acquired from the Maps management API.
  • The Authorization URL is specific to the Azure public cloud instance. Sovereign clouds have unique Authorization URLs and Azure Active directory configurations.
  • The Azure role based access control is configured from the Azure management plane via Azure portal, Powershell, CLI, Azure SDKs, or REST APIs.
  • Usage of the Azure Maps Web SDK allows for configuration based setup of an application for multiple use cases.
  • Currently Azure Active Directory v1.0 tokens are supported.

Type: oauth2
Flow: implicit
Authorization URL: https://login.microsoftonline.com/common/oauth2/authorize

subscription-key

This is a shared key which is provisioned when creating an Azure Maps resource through the Azure management plane via Azure portal, Powershell, CLI, Azure SDKs, or REST APIs. With this key, any application is authorized to access all REST APIs. In other words, these can currently be treated as master keys to the account which they are issued for. For publicly exposed applications our recommendation is to use server to server access of Azure Maps REST APIs where this key can be securely stored.

Type: apiKey
