    <p>it allows to retrieve the complete address (municipality, street and civic number) given the GPS position. It may also
        provide a list of services or public transport lines intersecting with the provided GPS position.
    </p>

    <h3>Inputs</h3>
    A JSON with these parameters:

    <dl class="message-properties">
        <dt>latitude
            <span class="property-type">number</span>
        </dt>
        <dd> latitude of a GPS position</dd>
        <dt>longitude
            <span class="property-type">number</span>
        </dt>
        <dd> longitude of a GPS position</dd>
    </dl>

    <h3>Outputs</h3>
    <dl class="message-properties">
        <dd> A JSON object with properties: • address: the street name. • number: the civic number. • addressUri: the URI identifying
            the civic number in the road graph. • municipality: the estimated municipality (it may not work properly on the
            municipalities borders) • municipalityUri: the URI identifying the municipality in the road graph.
        </dd>
    </dl>

    <h3>Details</h3>
    <p>The node can receive a JSON with the parameters described in the Inputs section and with them generate the output JSON.
        If the values are not present in the input JSON, these are read by those in the configuration. If they are not present
        in either part, an error is generated for the necessary parameters.</p>
