[OpenLayers-Users] Can Not Get Rule-based Stying to Work on KML

[Arnd Wippermann]

It seems, that OL doesn't parse ExtendedData in filter property

try simple attributes to see if your code works.
...
<ANNUAL>2242.269</ANNUAL>
<SPRING>2128.142</SPRING>
<SUMMER>2864.096</SUMMER>
<FALL>2002.744</FALL>
<WINTER>1974.092</WINTER>
... 

This should work.

Betreff: Re: [OpenLayers-Users] Can Not Get Rule-based Stying to Work on KML

OpenGSC,

Thanks for he advise, but I can't get it to work.

Please point out where I am wrong.

This my code now:

var map = new OpenLayers.Map("map");

var vector_style = new OpenLayers.Style({
        fillColor: "#ffffff",
        fillOpacity: 0.1,
        strokeWidth: 1,
        strokeColor: "#ffffff",
        strokeOpacity: 4,
});

var ruleLow = new OpenLayers.Rule({
                    filter: new OpenLayers.Filter.Comparison({
                       type: OpenLayers.Filter.Comparison.LESS_THAN,
                       property: "SUMMER",
                       value = 2000.0
                    }),
                    symbolizer: {
                      strokeColor: "#00ff00",
                      strokeWidth: 1,
                      fillColor: "#00ff00"
                    }
                });
var ruleHigh = new OpenLayers.Rule({
                    filter: new OpenLayers.Filter.Comparison({
                      type:
OpenLayers.Filter.Comparison.GREATER_THAN_OR_EQUAL_TO,
                      property: "SUMMER",
                       value = 2000.0
                    }),
                    symbolizer: {
                      strokeColor: "#ff0000",
                      strokeWidth: 1,
                      fillColor: "#ff0000"
                    }
                });

vector_style.addRules([ruleLow, ruleHigh]);

var vector_style_map = new OpenLayers.StyleMap({
'default': vector_style
});

var vectorlayer = new OpenLayers.Layer.Vector("SOLAR RAD BA", {
        strategies: [new OpenLayers.Strategy.Fixed()],
        protocol: new OpenLayers.Protocol.HTTP({
            url: "kml/ba_diffuse_summer.kml",
            format: new OpenLayers.Format.KML({
               extractStyles: false,
               extractAttributes: true,
               srsName: "EPSG:900913"
            })
        }),
        styleMap: vector_style_map
});

var googleLayer = new OpenLayers.Layer.Google("Google Satellite",
            {type: google.maps.MapTypeId.SATELLITE, numZoomLevels: 22}
        );

map.addLayers([googleLayer, vectorlayer]); map.addControl(new
OpenLayers.Control.LayerSwitcher());
map.zoomToMaxExtent();
