Reverse Geocoding

Reverse Geocoding

You can submit geocoordinates as input values to Informatica Address Verification and retrieve the closest address or addresses to the coordinates. To perform reverse geocoding, submit the address job in GeocodeToAddress mode.
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 if it finds no other address within ten metres of the address. 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 addresses corresponding to the geocoordinates, Address Verification does not return any address.
To retrieve addresses in GeocodeToAddress mode, configure the following properties in the
AVJob.schema.json
file:
  • SearchRadius. Defines the radius from the geocoordinates in which Address Verification searches for addresses. Find the property under
    Parameters
    CountrySets
    Process
    Geocode
    .
  • Value. Contains the latitude and longitude vales that constitute the geocoordinates. Find the property under
    Parameters
    IO
    Inputs
    Geocode
    . Use the property if you do not use the Latitude and Longitude properties.
  • Latitude and Longitude. Contain the latitude and longitude coordinates as discrete values. Find the properties under
    Parameters
    IO
    Inputs
    Geocode
    . Use the properties if you do not use the Value property.
Address Verification returns the following values in addition to each address:
  • Distance. Indicates the distance in metres from the address to the center of the search radius. Find the property under

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 be closer to the arrival point on a neighboring plot of land.
  • The MaxResultCount property governs the total number of addresses that reverse geocoding can return for the geocoordinates that you enter.
