Hello Robert, I don't know ArcGis Server, but I would look, if you can get your data in gml or kml. Otherwise you have to write your own parser. Arnd

I am trying to read in data coming from an ArcGIS Server in JSON format. Unfortunately, ArcGIS Server doesn't serve GeoJSON. Here is a sample of what the data looks like: { "results" : [ { "layerId" : 0, "layerName" : "Main_Gates", "displayFieldName" : "road_name", "foundFieldName" : "farm_id", "value" : "AS00136", "attributes" : { "point_location_id" : "232495", "farm_id" : "AS00136", "rapid_no" : "104", "road_name" : "Winslow Willowby Rd", "locality" : "Null", "x_nztm" : "1492934.61", "y_nztm" : "5131545.29", "Shape" : "Point" }, "geometryType" : "esriGeometryPoint", "geometry" : { "x" : 1492934.61, "y" : 5131545.29, "spatialReference" : { "wkid" : 2193 } } } ] } Any ideas how to get OL to read this into a Vector layer? Thanks, Robert >>> "Arnd Wippermann" <[email protected]> 7/03/2010 10:43 a.m. >>> Hi, i would think, that you have to use geojson instead of json, to get the geometry for the features.

Until the moment i haven't been able to achieve this. Following, is the relevant part of the code: var connect = new Ext.data.Connection(); connect.request({ url: 'mfbase/geoquery.php', params: { species: species, datai: datai, dataf: dataf }, success: function(response){ var resp = response.responseText; var json = new OpenLayers.Format.JSON(); var data = json.read(resp); //console.log(data[0].the_geom); var querylayer1 = new OpenLayers.Layer.Vector( 'Query1', { isBaseLayer: false, projection: wgs, geometryName: 'the_geom', } ); querylayer1.addFeatures(data); map.addLayer(querylayer1); } }) Any suggestions are more than welcomed :) Thanks to you all!
