Convert geometric coordinates to iModel's spatial coordinate system.
iModel coordinates in response array will be ordered in the same order as they were requested.
Response coordinate may contain warning property which identifies an issue with converted coordinate:
Out of useful range- indicates that the conversion was performed outside of the normal use of application of either Geographic Coordinate Reference Systems.Vertical datum convert error- indicates that a problem occurred during vertical datum conversion. The horizontal coordinates returned are valid but the returned elevation ordinate is unchanged or partially changed.
Instead of coordinate, response may contain an error:
Out of mathematical domain- conversions were requested outside of the area of the mathematical capacity of the conversion process for either Geographic Coordinate Reference Systems involved.
For more information on how iModels are geolocated see GeoLocation of iModels.

Response 401 Unauthorized
This response indicates that request lacks valid authentication credentials. Access token might not been provided, issued by the wrong issuer, does not have required scopes or request headers were malformed.
{ "error": { "code": "HeaderNotFound", "message": "Header Authorization was not found in the request. Access denied." } }
Response 429 Too many requests
This response indicates that the client sent more requests than allowed by this API for the current tier of the client.
{ "error": { "code": "RateLimitExceeded", "message": "The client sent more requests than allowed by this API for the current tier of the client." } }
Response headers
Number of seconds to wait until client is allowed to make more requests.

Error Response
Gives details for an error that occurred while handling the request. Note that clients MUST NOT assume that every failed request will produce an object of this schema, or that all of the properties in the response will be non-null, as the error may have prevented this response from being constructed.
