Hi all,
I am creating vector layers in format KML. I have the sources in drop box to avoid CORS, but when I load them in the map they have no features. Any ideas about this issue will be very much appreciated.
Thank you
JJ.
Please see below how I am doing it.
var layers = [
wms_bmid_pipes = new ol.layer.Vector({
source: new ol.source.Vector({
url: 'https://dl.dropboxusercontent.com/s/ea4qzzuyk5i2mxt /geid_ws-bmid-pipes.kml?dl=0',
format: new ol.format.KML()
})
})
];
Since the layer does not show up in the map I ran the code below to check how many features it has (this code comes from the open layers web site). It turns out that in the console I get "Count after change: 0" , meaning that there are no features.
wms_bmid_pipes.getSource().on('change', function(evt){
var source = evt.target;
if (source.getState() === 'ready') {
var numFeatures = source.getFeatures().length;
console.log("Count after change: " + numFeatures);
}
});
The point is that the wms_bmid_pipes contains this:
