Spatial - Post Point In Polygon

Reference

Service:: Maps

API Version:: 2022-08-01

Use to determine if a given a point is inside a set of polygons.

Note

Azure Maps Spatial service retirement

The Azure Maps Spatial service is now deprecated and will be retired on 9/30/25. For more information, see End of Life Announcement of Azure Maps Spatial.

The Post Point In Polygon API is an HTTP POST request that returns a boolean value indicating whether a point is inside a set of polygons. The user data may contain Polygon and MultiPolygon geometries, other geometries will be ignored if provided. If the point is inside or on the boundary of one of these polygons, the value returned is true. In all other cases, the value returned is false. When the point is inside multiple polygons, the result will give intersecting geometries section to show all valid geometries (referenced by geometryId) in user data. The maximum number of vertices accepted to form a Polygon is 10,000.

URI Parameters

Name	In	Required	Type	Description
format	path	True	JsonFormat	Desired format of the response. Only `json` format is supported.
geography	path	True	string	Location of the Azure Maps Account. Valid values are us (East US, West Central US, West US 2) and eu (North Europe, West Europe). This parameter is required when a `udid` is supplied in the request. For example, if the Azure Maps Account is located in East US, only requests to us geography will be accepted.

Name	Required	Type	Description
x-ms-client-id		string	Specifies which account is intended for usage in conjunction with the Microsoft Entra ID security model. It represents a unique ID for the Azure Maps account and can be retrieved from the Azure Maps management plane Account API. To use Microsoft Entra ID security in Azure Maps see the following articles for guidance.

Security

AADToken

These are the Microsoft Entra OAuth 2.0 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.

Notes

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 Microsoft Entra ID 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.

Scopes

Name	Description
https://atlas.microsoft.com/.default	https://atlas.microsoft.com/.default

subscription-key

This is a shared key that 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
In: header

SAS Token

This is a shared access signature token is created from the List SAS operation on the Azure Maps resource through the Azure management plane via Azure portal, PowerShell, CLI, Azure SDKs, or REST APIs.

With this token, any application is authorized to access with Azure role-based access controls and fine-grain control to the expiration, rate, and region(s) of use for the particular token. In other words, the SAS Token can be used to allow applications to control access in a more secured way than the shared key.

For publicly exposed applications, our recommendation is to configure a specific list of allowed origins on the Map account resource to limit rendering abuse and regularly renew the SAS Token.
