Then what would be good is to code it as open-source so that people can join effort.

Did you check the packages of geolocalisation developed by Hernan Morales?

    Hi Sven,

    thanks for your fast response and the snippets. I scanned the
    different geocoder classes from "geopy" and also the OSM Nominatim
    docs. Indeed, it is not hard, ..... but if there is already a
    package, why not using it :-)

    maybe i start to write such a lib.

    Thanks,
    Volkert

            Dear all,

            do we have a package to access the a geocoder service?
            Something similar to "geopy".

        As far as I know there is no such library.

        We have it internally, but that part is not open source. But
        it is not so hard to do yourself.

        Here is an example for forward geocoding (address -> coordinates):

        ZnClient new
                url: 'http://nominatim.openstreetmap.org/search
        <http://nominatim.openstreetmap.org/search>';
                queryAt: #format put: 'json';
                queryAt: #addressdetails put: '1';
                queryAt: #q put: 'Villerspark 5, 3500 Hasselt';
                queryAt: #countrycodes put: 'be';
                accept: ZnMimeType applicationJson;
                contentReader: [ :entity | STONJSON fromString: entity
        contents ];
                get.

        Here is an example for reverse geocoding (coordinates -> address):

        ZnClient new
                url: 'http://nominatim.openstreetmap.org/reverse
        <http://nominatim.openstreetmap.org/reverse>';
                queryAt: #format put: 'json';
                queryAt: #lon put: 5.33732 asString;
                queryAt: #lat put: 50.926 asString;
                accept: ZnMimeType applicationJson;
                contentReader: [ :entity | STONJSON fromString: entity
        contents ];
                get.

        These are against the OpenStreetMap Nomatim service, others
        are similar.

        HTH,

        Sven
