[OpenLayers-Users] Accessing user defined data from a OpenLayers application

[Gery .]

it looks good to me, probably modifying your code like this?:

new OpenLayers.Layer.Vector("KML", {
            strategies: [new OpenLayers.Strategy.Fixed()],
            protocol: new OpenLayers.Protocol.HTTP({
                url: "kml/YOUR-KML.kml",
                format: new OpenLayers.Format.KML({
                    extractStyles: true, 
                    extractAttributes: true,
                    maxDepth: 2
})
            })
        })

This is the KML file I am using. I have tried with some other KML files, but still it does not work. 

Thanks,
Nipuni

Probably the kml structure is wrong, is it?

Hi,

I have tried displaying data from GeoJSON file which worked fine with both localhost and local file location. But when I tried to get data from a KML file it does not show data on the vector layer, only the base layers is visible. 


This is my vector layer instantiation for retrieving KML data. 

vector_layer = new OpenLayers.Layer.Vector('KML Data',
{ projection:new OpenLayers.Projection('EPSG:4326'),


protocol:new OpenLayers.Protocol.HTTP({url:'flicker_data.kml', format:new OpenLayers.Format.KML({extractAttributes:true})})
,stratagies:new OpenLayers.Strategy.Fixed()});

Thanks,


Nipuni

I am assuming that your application will run off a server? If so, then no problem putting the data as xml file on that server and using http to access it (eg, that is how you normally fetch GML).



If you are working "server-less" then its a whole different ball game. For starters you will need to use a script protocol to get around browser security restrictions on local files. To make your life easier, if at all possible use a server. If you can feed your data to a spatial database like PostGIS and extract with WMS/WFS server like geoserver or mapserver, then it will be easier still.
