Wie xml-Datei (Liste von verschiedenen Örtlichkeiten) per JavaScript in einer OSM-Webkarte anzeigen?

0

Moin,

wie muss man vorgehen,um eine xml-Datei(Liste von verschiedenen Örtlichkeiten) in einer Openstreetmap-Karte angezeigt zu bekommen?

Beispiel für eine Gestaltung einer Grundkarte in einer Html mittels CSS und Javascript ist hier: http://wiki.openstreetmap.org/wiki/DE:Karte_in_Webseite_einbinden

Aber wie muss ich dann weiter gehen?

Gruß

Thal

As far as I understand, the question is about displaying data stored in xml on OSM map.

Do you know if a parser still exist for your XML format? What is the structure of your format.

The example given use Openlayers, but Leaflet can also be used if it is easier for your data.

Moin,

bislang bin ich kein Schritt weiter gekommen.

in welcher Zeile muss ich den Code einfügen?

Folgende Dateien sind vorhanden:

function jumpTo(lon, lat, zoom) {
    var x = Lon2Merc(lon);
    var y = Lat2Merc(lat);
    map.setCenter(new OpenLayers.LonLat(x, y), zoom);
    return false;
}

function Lon2Merc(lon) {
    return 20037508.34 * lon / 180;
}

function Lat2Merc(lat) {
    var PI = 3.14159265358979323846;
    lat = Math.log(Math.tan( (90 + lat) * PI / 360)) / (PI / 180);
    return 20037508.34 * lat / 180;
}

function addMarker(layer, lon, lat, popupContentHTML) {

    var ll = new OpenLayers.LonLat(Lon2Merc(lon), Lat2Merc(lat));
    var feature = new OpenLayers.Feature(layer, ll); 
    feature.closeBox = true;
    feature.popupClass = OpenLayers.Class(OpenLayers.Popup.FramedCloud, {minSize: new OpenLayers.Size(300, 180) } );
    feature.data.popupContentHTML = popupContentHTML;
    feature.data.overflow = "hidden";

    var marker = new OpenLayers.Marker(ll);
    marker.feature = feature;

    var markerClick = function(evt) {
        if (this.popup == null) {
            this.popup = this.createPopup(this.closeBox);
            map.addPopup(this.popup);
            this.popup.show();
        } else {
            this.popup.toggle();
        }
        OpenLayers.Event.stop(evt);
    };
    marker.events.register("mousedown", feature, markerClick);

    layer.addMarker(marker);
    map.addPopup(feature.createPopup(feature.closeBox));
}

function getCycleTileURL(bounds) {
   var res = this.map.getResolution();
   var x = Math.round((bounds.left - this.maxExtent.left) / (res * this.tileSize.w));
   var y = Math.round((this.maxExtent.top - bounds.top) / (res * this.tileSize.h));
   var z = this.map.getZoom();
   var limit = Math.pow(2, z);

   if (y < 0 || y >= limit)
   {
     return null;
   }
   else
   {
     x = ((x % limit) + limit) % limit;

     return this.url + z + "/" + x + "/" + y + "." + this.type;
   }
}

Dies ist die tom.js(-Datei).

Und dies ist die Index.html(-Datei):

In welcher Datei muss man dann den xml-Link zur Datei hinzufügen. Natürlich sollen mittels der XML-Datei die Marker aus dem Code heraus ausgelagert werden.

Dieser oben genannte Code stammt von hier: http://wiki.openstreetmap.org/wiki/DE:Karte_in_Webseite_einbinden

Ich hoffe ich habe dabei nichts übersehen,wie man zu einer Lösung kommt.

Hey thal, dein Openlayers-Ploblem scheint alles andere als eine FAQ zu sein.

Ich halte es daher für besser und aussichtsreicher, wenn du die Fragestellung im deutschen Unterforum auf http://forum.osm.org nochmal stellst. Da lesen wohl mehr OL-Experten mit.

Some hints are listed at the website of OpenLayers.org ... they have a collection of examples there.

About the Leaflet framework, have a look at their website.
