Hi,
If you want to have points and lines on an own layer you can try
1. create two layers to read the same kml file
2. add an own parameter to your layers (geom:"OpenLayers.Geometry.Point" or
geom:"OpenLayers.Geometry.Point" )
3. register beforefeatureadded for the layers, where you separate the
feature by geometryType
...
var kmlLines = new OpenLayers.Layer.Vector("KML tracks", {
geom:"OpenLayers.Geometry.LineString",
protocol: new OpenLayers.Protocol.HTTP({
url: "test.kml",
format: new OpenLayers.Format.KML({extractStyles: false,
extractAttributes: true})
}),
strategies: [new OpenLayers.Strategy.Fixed()],
style: {fillColor: "red", strokeColor: "blue", strokeWidth: 4,
strokeOpacity: 0.5, pointRadius: 5},
projection: new OpenLayers.Projection("EPSG:4326")
});
kmlPoints.events.register("beforefeatureadded", kmlPoints, function (obj) {
return( addFeatureByGeometry(obj, this));});
kmlLines.events.register("beforefeatureadded", kmlLines, function (obj) {
return( addFeatureByGeometry(obj, this));});
...
function addFeatureByGeometry(obj, lyr)
{
if(obj.feature.geometry.CLASS_NAME==lyr.geom)
return true;
else
return false;
}
>From Layer\Vector.js
* Supported map event types (in addition to those from
<OpenLayers.Layer>):
* beforefeatureadded - Triggered before a feature is added. Listeners
* will receive an object with a *feature* property referencing the
* feature to be added. To stop the feature from being added, a
* listener should return false.
This way you can separate the feature also by given attributes.

Betreff: [OpenLayers-Users] Re: Reading KML file into multiple layers
The pre condition is that I have a KML file which contains both Placemarks
and Track(s).
It is no option to seperate it into multiple files.
Is there no way to extract portions, or let generate multiple layers from
one KML?
Thanks for your help.
