Finding Street Intersections

The geocodeIntersections operation searches for the intersections between two or more streets. The response contains the coordinates of the intersections.

The following l isting shows the general structure of the operation in the WSDL file of the MapTP Geocoder 5.1 Service:

   ...

      <message name="geocodeIntersectionsRequest">

          <part name="RequestHeader" type="tns:RequestHeader"/>

          <part name="GeocodeIntersectionsRequest" type="tns:GeocodeIntersectionsRequest"/>

      </message>

      <message name="geocodeIntersectionsResponse">

         <part name="GeocodeIntersectionsResponse " type="tns:GeocodeIntersectionsResponse"/>

      </message>

   </operation>
   ...
  </portType>
  ...

 

Request

GeocodeIntersectionsRequest contains the parameters of a geocodeIntersections operation.




Field Description
Intersections The Intersections array contains all found intersections of type Intersection.
Properties Not used.







 

Field Description
Addresses

An Intersection contains an array of Address elements used for specifying the streets to be taken into account in the intersection search.

Note: Not all fields of an address are necessary to identify the street. Usually, only the following fields are used:

  • Street- defines the name of the street
  • City - defines the city where the street is.
  • Country – defines a country where the city is.
  • County
  • ZIP
Properties Not used.



Response

The GeocodeIntersectionsResponse element contains the response of a geocodeIntersections request in the Intersections array.



Field Description
Intersections

The Intersections array contains the point of intersection between the two given streets.

Properties Not used

 

 

Field Description
IntersectionPoints

The IntersectionPoints array contains an array of coordinates for each found intersection. Each found intersection can then be identified by its coordinates.

Bounds The Bounds element contains the coordinates of two corners that describe a bounding box containing all found intersections.
GeocodedAddresses

The GeocodedAddresses array contains a GeocodedAddress element for each address that was specified in the request.
Properties Not used.

 

The GeocodedAddresses array contains a GeocodedAddress element for each address that was specified in the request.


A GeocodedAddress element contains the following information:

  • If an ID is passed for the input address in the request, the ID field contains this ID. Otherwise, this field is empty.
  • The HouseNo, Street, ZIP, etc. fields contain the input address data. Only those fields are returned that have been provided in the request.
  • The Alternatives array contains the geocoding results. If more than one address was found for the given address data, multiple geocoding results are provided in the Alternatives array. Note that the maximum number of returned geocoding results can be defined in the request with MaxNoOfAlternatives. A geocoding result is contained in a GeocodeAddress.Alternative element. The structure of a GeocodeAddress.Alternative element is shown in the following figure:

Fields of a GeocodeAddress.Alternative element:

Field Description
ID
 A unique identifier of the request. If an ID is passed in the request, it is returned in the response. Otherwise, this field is empty.
HouseNo The house number of the geocoding result (if available).
Street The street of the geocoding result.
ZIP
 The ZIP code of the geocoding result.
City
 The city of the geocoding result.
District
 The district.
County
 The county.
State
 The state.
Country
 The country of the geocoding result.
Quality
 The quality of the result. The following quality levels are defined:
  • Exact: The result matches the input address exactly. Even the house numbers of the input address and the result are identical.
  • Street: The result matches the input address on street level.
  • ZIP: The result matches the input address on ZIP code level.
  • District: The result matches the input address on city district level.
  • City: The result matches the input address on city level.
  • Mismatch: The result does not match the input address.
Similarity
 The similarity between the result and the given input address in a scale from "0.00" (mismatch) to "1.00" (direct hit). Besides the Quality element, this field provides information on the accuracy of the result.
Coordinate
 The latitude and longitude of the result.
