Hi,
I am trying to show an inline kml string onto a OSM layer (using the
proper projection transformations).
Everything seems to work, except the features in the KML string are
not shown properly.
I use this code:
function init(){
var options = {
projection: new OpenLayers.Projection("EPSG:900913"),
displayProjection: new OpenLayers.Projection("EPSG:
4326"),
units: "km",
numZoomLevels: 18,
maxResolution: 156543.0339,
maxExtent: new OpenLayers.Bounds(-20037508, -20037508,
20037508, 20037508.34)
};
map = new OpenLayers.Map('map', options);
// create OSM layer
var mapnik = new OpenLayers.Layer.TMS(
"OpenStreetMap (Mapnik)",
"http://a.tile.openstreetmap.org/";,
{
type: 'png', getURL: osm_getTileURL,
displayOutsideMaxExtent: true,
attribution: '<a href="http://
www.openstreetmap.org/">OpenStreetMap</a>'
}
);
map.addLayer(mapnik);
// Add a KML as inline String
var kmlString = '<?xml version="1.0"
encoding="UTF-8"?><kml xmlns="http://earth.google.com/kml/2.1
"><Document><Style
id="marker"><IconStyle><Icon><href>http://localhost:3000/openlayers/img/marker-green.png
</href></Icon></IconStyle></Style><Placemark id="13856"><name>place
name</name><description>NULL::character varying</
description><styleUrl>#marker</
styleUrl><Point><altitudeMode>relativeToGround</
altitudeMode><coordinates>23.29555556,-17.98611111</coordinates></
Point></Placemark><Placemark id="13852"><name>place name 2</
name><description>NULL::character varying</
description><styleUrl>#marker</
styleUrl><Point><altitudeMode>relativeToGround</
altitudeMode><coordinates>24.56638889,-17.54027778</coordinates></
Point></Placemark></Document></kml>';
kmlLayer = new OpenLayers.Layer.Vector("KML", {
projection: new
OpenLayers.Projection("EPSG:4326"),
format: OpenLayers.Format.KML,
formatOptions: {
extractStyles: true,
extractAttributes: true
}
});
var kmlParser = new OpenLayers.Format.KML();
var kmlFeatures = kmlParser.read(kmlString);
kmlLayer.addFeatures(kmlFeatures);
map.addLayer(kmlLayer);
bounds = getFeaturesBounds(kmlLayer.features);
map.zoomToExtent(bounds.transform(map.displayProjection,
map.getProjectionObject()));
}
When I read the same KML from a file and use this code, the data is
shown correctly:
kmlLayer = new OpenLayers.Layer.GML("KML",
"kml/data.kml",
{
projection: new
OpenLayers.Projection("EPSG:4326"),
format: OpenLayers.Format.KML,
formatOptions: {
extractStyles: true,
extractAttributes: true
}
});
My guess is that I should do something else to add the features to the
kmlLayer. Like a projection maybe?
Thanks for your time.
