Address Verification applies a search radius to the geocoordinates to define an area in which to search for addresses. The geocoordinates are the center of the search area. The default search radius is 50 meters. You can set the radius to a value between 10 metres and 200 meters.

You can enter a pair of geocoordinates as a single input value, or you can enter the latitude and longitude coordinates as discrete input values. Address Verification will return one address or multiple addresses, depending on the parameters that you set and the distance between the addresses.

Address Verification returns the address closest to the geocoordinates that you enter. If any address lies within ten meters of the closest address, Address Verification returns the closest address and also each address within the ten-meter range. Address Verification also returns the distance from the geocoordinates of each output address and the direction in which the address lies.

If Address Verification cannot find any address within the search radius, Address Verification does not return an address.

To retrieve addresses in GeocodeToAddress mode, configure the following properties

in the

AVJob.schema.json

file

:

Consider the following rules and guidelines when you configure an address job for reverse geocoding:

Address Verification follows the World Geodetic System standards (WGS 84) for geocoding.
Reverse geocoding requires arrival point reference data and returns addresses with arrival point precision.
The geocoordinates that you provide may identify a location on a given plot of land but may be closer to the arrival point on an adjacent plot of land. In this case, Address Verification selects the address of the adjacent plot as it represents the nearest arrival point.
The MaxResultCount property governs the total number of addresses that reverse geocoding can return for the geocoordinates that you enter.

To read the list of countries that support reverse geocoding, see Appendix B: Reverse Geocoding Coverage.
