Spatial - Post Buffer

Applies to: S1 pricing tier.

This API returns a FeatureCollection where each Feature is a buffer around the corresponding indexed Feature of the input. The buffer could be either on the outside or the inside of the provided Feature, depending on the distance provided in the input. There must be either one distance provided per Feature in the FeatureCollection input, or if only one distance is provided, then that distance is applied to every Feature in the collection. The positive (or negative) buffer of a geometry is defined as the Minkowski sum (or difference) of the geometry with a circle of radius equal to the absolute value of the buffer distance. The buffer API always returns a polygonal result. The negative or zero-distance buffer of lines and points is always an empty polygon. The input may contain a collection of Point, MultiPoint, Polygon, MultiPolygon, LineString and MultiLineString. GeometryCollection will be ignored if provided.

URI Parameters

Name In Required Type Description
format
path True

Desired format of the response. Only json format is supported.

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

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.

Request Body

Name Type Description
geometries

A valid GeoJSON FeatureCollection object type. Please refer to RFC 7946 for details. All the feature's properties should contain geometryId, which is used for identifying the geometry and is case-sensitive.

Responses

Name Type Description
200 OK

OK

400 Bad Request

Bad request: one or more parameters were incorrectly specified or are mutually exclusive.

401 Unauthorized

Access denied due to invalid subscription key or invalid Azure Active Directory bearer token. Make sure to provide a valid key for an active Azure subscription and Maps resource. Otherwise, verify the WWW-Authenticate header for error code and description of the provided AAD bearer token.

Headers

  • WWW-Authenticate: string
403 Forbidden

Permission, capacity, or authentication issues.

404 Not Found

Not Found: the requested resource could not be found, but it may be available again in the future.

500 Internal Server Error

An error occurred while processing the request. Please try again later.

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
