Search - Get Reverse Geocoding

Use to get a street address and location info from longitude and latitude coordinates.

The Get Reverse Geocoding API is an HTTP GET request used to translate a coordinate (example: 37.786505, -122.3862) into a human understandable street address. Useful in tracking applications where you receive a GPS feed from the device or asset and wish to know the address associated with the coordinates. This endpoint will return address information for a given coordinate.

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.

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 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.
  • For more information on Microsoft identity platform, see Microsoft identity platform overview.

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.

Definitions

Name Description
Address

The address of the result

AdminDistricts

The subdivision name in the country or region for an address. This element is typically treated as the first order administrative subdivision, but in some cases it also contains the second, third, or fourth order subdivision in a country, dependency, or region.

CalculationMethodEnum

The method that was used to compute the geocode point.

ConfidenceEnum

The level of confidence that the geocoded location result is a match. Use this value with the match code to determine for more complete information about the match.

The confidence of a geocoded location is based on many factors including the relative importance of the geocoded location and the user’s location, if specified.

ErrorAdditionalInfo

The resource management error additional info.

ErrorDetail

The error detail.

ErrorResponse

FeatureCollectionEnum

The type of a FeatureCollection object must be FeatureCollection.

FeaturesItem
FeatureTypeEnum

The type of a feature must be Feature.

GeocodePoints

A collection of geocode points that differ in how they were calculated and their suggested use.

GeocodingResponse

This object is returned from a successful Geocoding call

GeoJsonPoint

A valid GeoJSON Point geometry type. Please refer to RFC 7946 for details.

Intersection

The address of the result.

MatchCodesEnum

One or more match code values that represent the geocoding level for each location in the response.

For example, a geocoded location with match codes of Good and Ambiguous means that more than one geocode location was found for the location information and that the geocode service did not have search up-hierarchy to find a match.

Similarly, a geocoded location with match codes of Ambiguous and UpHierarchy implies that a geocode location could not be found that matched all the provided location information, so the geocode service had to search up-hierarchy and found multiple matches at that level. An example of up an Ambiguous and UpHierarchy result is when you provide complete address information, but the geocode service cannot locate a match for the street address and instead returns information for more than one RoadBlock value.

The possible values are:

Good: The location has only one match or all returned matches are considered strong matches. For example, a query for New York returns several Good matches.

Ambiguous: The location is one of a set of possible matches. For example, when you query for the street address 128 Main St., the response may return two locations for 128 North Main St. and 128 South Main St. because there is not enough information to determine which option to choose.

UpHierarchy: The location represents a move up the geographic hierarchy. This occurs when a match for the location request was not found, so a less precise result is returned. For example, if a match for the requested address cannot be found, then a match code of UpHierarchy with a RoadBlock entity type may be returned.

Properties
ReverseGeocodingResultTypeEnum

Specify entity types that you want in the response. Only the types you specify will be returned. If the point cannot be mapped to the entity types you specify, no location information is returned in the response. Default value is all possible entities. A comma separated list of entity types selected from the following options.

  • Address
  • Neighborhood
  • PopulatedPlace
  • Postcode1
  • AdminDivision1
  • AdminDivision2
  • CountryRegion

These entity types are ordered from the most specific entity to the least specific entity. When entities of more than one entity type are found, only the most specific entity is returned. For example, if you specify Address and AdminDistrict1 as entity types and entities were found for both types, only the Address entity information is returned in the response.

UsageTypeEnum

The best use for the geocode point. Each geocode point is defined as a Route point, a Display point or both. Use Route points if you are creating a route to the location. Use Display points if you are showing the location on a map. For example, if the location is a park, a Route point may specify an entrance to the park where you can enter with a car, and a Display point may be a point that specifies the center of the park.

Parcel

string

The geocode point was matched to the center of a parcel.

Rooftop

string

The geocode point was matched to the rooftop of a building.

ConfidenceEnum

The level of confidence that the geocoded location result is a match. Use this value with the match code to determine for more complete information about the match.

The confidence of a geocoded location is based on many factors including the relative importance of the geocoded location and the user’s location, if specified.

Name Type Description
High

string

If the confidence is set to High, one or more strong matches were found. Multiple High confidence matches are sorted in ranked order by importance when applicable. For example, landmarks have importance but addresses do not.

If a request includes a location or a view, then the ranking may change appropriately. For example, a location query for "Paris" returns "Paris, France" and "Paris, TX" both with High confidence. "Paris, France" is always ranked first due to importance unless a user location indicates that the user is in or very close to Paris, TX or the map view indicates that the user is searching in that area.

Low

string

Medium

string

In some situations, the returned match may not be at the same level as the information provided in the request. For example, a request may specify address information and the geocode service may only be able to match a postal code. In this case, if the geocode service has a confidence that the postal code matches the data, the confidence is set to Medium and the match code is set to UpHierarchy to specify that it could not match all of the information and had to search up-hierarchy.

If the location information in the query is ambiguous, and there is no additional information to rank the locations (such as user location or the relative importance of the location), the confidence is set to Medium. For example, a location query for "148th Ave, Bellevue" may return "148th Ave SE" and "148th Ave NE" both with Medium confidence.

If the location information in the query does not provide enough information to geocode a specific location, a less precise location value may be returned and the confidence is set to Medium. For example, if an address is provided, but a match is not found for the house number, the geocode result with a Roadblock entity type may be returned.
