Hi guys
I'm developing a web service where it will be possible to export each vector
layer to GML, GeoJSON, Shapefile...
So, I have a vector layer defined this way:
traverseHaughton = new OpenLayers.Layer.Vector("Haughton Traverses", {
strategies: [new OpenLayers.Strategy.BBOX(),
saveStrategyTraverse],
styleMap: vectorStyleMap,
protocol: new OpenLayers.Protocol.WFS({
version: "1.0.0",
url: "http://***:8080/geoserver/wfs?";,
featureType: "traverse_haughton",
srsName: "EPSG:26916",
featurePrefix: "topp",
geometryName: "the_geom"
})
});
As you can see, the projection is EPSG:26916, which is also defined for the
map object.
The problem is when I'm using the .write() function. Even though a
projection is defined, it does not translate into the GML or GeoJSON.
GeoJSON example:
var geojson = new OpenLayers.Format.GeoJSON();
geojson.externalProjection = map.projection;
geojson.internalProjection = map.getProjectionObject();
var ingeoj = geojson.write(layer.features);
ingeoj =
"{"type":"FeatureCollection","features":[{"type":"Feature","id":"line_haughton.100934661","properties":{"id":"1","name":"2","notes":"344"},"geometry":{"type":"MultiLineString","coordinates":[[[422336.53759006,8363423.4713272],[422626.89012912,8362411.92054595],[422336.53759006,8361400.3697647]]]}},{"type":"Feature","id":"line_haughton.101521704","properties":{"id":"1","name":"2","notes":"3"},"geometry":{"type":"MultiLineString","coordinates":[[[423722.73680883,8367984.8160542],[425034.00634008,8366186.5035542],[425914.4301682,8366898.3355855]]]}}]}"
There is no CRS property. The same thing is happening with GML. I think this
is causing me problem when I try to use GDAL/OGR on server side.
Do any of you know how to add the projection information into a GML of
GeoJSON created by openlayers?
Thanks
Maxime
