[OpenLayers-Users] Problem with polygon layer

[Arnd Wippermann]

There is a format option "ignoreExtraDims".

OpenLayers.Format.GeoJSON = OpenLayers.Class(OpenLayers.Format.JSON, {

    /**
     * APIProperty: ignoreExtraDims
     * {Boolean} Ignore dimensions higher than 2 when reading geometry
     * coordinates.
     */ 
    ignoreExtraDims: false,


with set to true the geojson file will show up as expected:

var polygon_layer = new OpenLayers.Layer.Vector("Polygon Test", {
    strategies: [new OpenLayers.Strategy.Fixed()],
    protocol: new OpenLayers.Protocol.HTTP({
        url: "zoning_3857.geojson",
        format: new OpenLayers.Format.GeoJSON({extractStyles: false ,
extractAttributes: true, ignoreExtraDims:true})
    })
});
map.addLayer(polygon_layer);

Betreff: Re: [OpenLayers-Users] Problem with polygon layer

I figured out my problem.  In the GeoJSON file my coordinates were in XYZ
format (see below) once I removed the Z cooridinate value everything worked
fine.

[ -8932119.2363246344, 4964545.5571182314, 0.0 ]

Why did Openlayers not display my GeoJSON file when the file was in 3d
format?
