[GIS] My GeoJson will not display on a Vector Layer in Openlayers

geojsonopenlayers-2

I have geoJson from the the USGS that I am downloading to my server.

It validates just fine with geojsonlint.

When I past the JSON into this Openlayers example it says it is bad input json.

My Code to display it on a vector layer is as follows where variable mapProjection is EPSG:900913.

I have spent 3 days on this now, and cannot get it do display. What am I doing wrong?

Added Information, I have tried this method:

vectorLayer = new OpenLayers.Layer.Vector("MyLayer");
map.addLayer(vectorLayer);

function handler(request) {

var geojson_format = new OpenLayers.Format.GeoJSON({
    'internalProjection': map.baseLayer.projection,
    'externalProjection': new OpenLayers.Projection("EPSG:4326")
});

vectorLayer.addFeatures(geojson_format.read(request.responseText));
}

var request = OpenLayers.Request.GET({
    url: "geojson.json",
    callback: handler
});

and have been able to see the json in variable request in the handler function. It has to be something to do with the format of the data.

I am on a windows system and writing the data to a txt file, then serving it to my openlayers app via IIS. I have the correct mime types set up for json already.

    var geojson_format = new OpenLayers.Format.GeoJSON({
                'internalProjection': mapProjection,
                'externalProjection': wgs84
                });

var newlayer = new OpenLayers.Layer.Vector(
            layername, 
            {
            style: style_mark,
            projection: wgs84,                          
            strategies: [new OpenLayers.Strategy.Fixed()],
            protocol: new OpenLayers.Protocol.HTTP
                    ({
                            url: '/data/earthquake_day.json?' + forcedownload,
                            format: geojson_format
                    })
            }
    );
 map.addLayers([newlayer]);

This is the Geojson ..

Best Answer

You are getting this issue, because your GeoJSON data has Z coordinates.

By Default, OpenLayer's GeoJSON parser fails when it finds more than two coordinates (i.e X & Y).

To solve this issue, you must set the GeoJSON.ignoreExtraDims parameter to true.

Here is a sample JSFiddle which shows the code in actions.
