What is wrong with my geoJSON?

CesiumJS

The geoJSON sandcastle examples runs perfectly with me, but when I use my own geoJSON file as a data source nothing appear. Please help:

Below is my geoJSON data source:

{ "type": "Feature", "properties": { "OBJECTID": 20, "ENGID": "40RBN5319301351"}, "geometry": { "type": "Polygon", "coordinates": [ [ [ 54.566124539478878, 24.406021338476325 ], [ 54.566148107752099, 24.406028017955055 ], [ 54.566115732828465, 24.406123836089698 ], [ 54.566235456768659, 24.406157760188982 ], [ 54.566255574031182, 24.406098193520144 ], [ 54.566281975778445, 24.406105667739457 ], [ 54.566279060022957, 24.406114304250391 ], [ 54.566329951512451, 24.406128725476261 ], [ 54.566371950924683, 24.406004421274567 ], [ 54.566292775469798, 24.405981990105861 ], [ 54.566286944486251, 24.405999236057994 ], [ 54.566270925041493, 24.405994699916651 ], [ 54.566268584486721, 24.406001612608108 ], [ 54.566239349486047, 24.405993334604545 ], [ 54.566241680361216, 24.405986412731547 ], [ 54.566182308651392, 24.405969589467993 ], [ 54.566175004474289, 24.405991180502262 ], [ 54.566138240189531, 24.405980768499898 ], [ 54.566124539478878, 24.406021338476325 ] ] ] } }

and below is the source code:

//Create the viewer
var viewer = new Cesium.Viewer('cesiumContainer');
Cesium.viewerEntityMixin(viewer);

var dataSource = new Cesium.GeoJsonDataSource();
viewer.dataSources.add(dataSource);
dataSource.loadUrl('../../SampleData/bldgs.geojson');

Even the original geojson example is not working when I run it locally.

Any idea?

By the way, I am using IIS as a web server, and following is the error I got when running the application using Chrom:

XMLHttpRequest cannot load http://hqtpssdd0082d/Cesium/Apps/Sandcastle/ne_10m_us_states.topojson. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:52956' is therefore not allowed access. GeoJSON.html:1

IIS by default does not serve file extensions that it doesn’t recognize. This includes .geojson and .topojson files. You have to configure it to tell it the correct MIME type to use for those extensions. http://stackoverflow.com/questions/8158193/how-to-allow-download-of-json-file-with-asp-net

Also, if you want to load files from a different server, you will also need to enable CORS headers on the server hosting the data file. http://enable-cors.org/server_iis7.html

Many thanks Scott Hunter, it is working now.
