Node-RED block in Snap4City Microservice library node-red-contrib-snap4city-developer is "geometry-search-near-gps-position">
    <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>
    <ol class="node-ports">
        <li>ServiceUri Array
            <dl class="message-properties">
                <dd> Returns an array containing the servicesUri of each service found</dd>
            </dl>
        </li>
        <li>Address Information
            <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. • intersect: array of objects with properties: o name: name of the intersecting service
                    or public transport line. o uri: URI of the intersecting service or public transport line. o class: URI
                    representing the class o type: type of geometry intersecting the GPS position, can be lineString or Polygon
                    o routeType: type of route can be Bus, LightRail, Ferry, Train o agency: name of the agency providing
                    the service o direction: direction of the line o distance: distance of the GPS position with the intersecting
                    geometry
                </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>
