<dependency>
    <groupId>org.apache.camel</groupId>

    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

geocoder:address:name[?options]
geocoder:latlng:latitude,longitude[?options]

Options

Unknown macro: {div}

Property	Default	Description

Message Headers

Unknown macro: {div}

Header	Description
`CamelGeoCoderStatus`	Status code from the geocoder library. If status is `GeocoderStatus.OK` then additional headers is enriched
`CamelGeoCoderAddress`	The formatted address
`CamelGeoCoderLatlng`	The latitude and longitude of the location. Separated by comma.
`CamelGeoCoderCountryLong`	The country long name. May only be available in latlng mode.

Samples

In the example below we get the latitude and longitude for Paris, France

  from("direct:start")
    .to("geocoder:address:Paris, France")

If you provide a header with the CamelGeoCoderAddress then that overrides the endpoint configuration, so to get the location of Copenhagen, Denmark we can send a message with a headers as shown:

template.sendBodyAndHeader("direct:start", "Hello", GeoCoderConstants.ADDRESS, "Copenhagen, Denmark");

To get the address for a latitude and longitude we can do:

  from("direct:start")
    .to("geocoder:latlng:40.714224,-73.961452")
    .log("Location ${header.CamelGeocoderAddress} is at lat/lng: ${header.CamelGeocoderLatlng} and in country ${header.CamelGeoCoderCountryShort}")

Which will log

Location 285 Bedford Avenue, Brooklyn, NY 11211, USA is at lat/lng: 40.71412890,-73.96140740 and in country US
