-# Vector Use Cases
-
-These use cases describe common scenarios for loading, rendering, and editing vector data.
-
-## Load data once from static file
-
-User has a static file (e.g. GeoJSON) hosted on the same origin as their application.  User expects data to be loaded and rendered over a raster tile based layer (e.g. WMS).  Data may be in a different coordinate reference system than map.
-
-**Alternative 1**
-
-```js
-var raster = new ol.layer.TileLayer({
-  source: new ol.source.TiledWMS({
-    url: 'http://demo.opengeo.org/geoserver/wms',
-    params: {'LAYERS': 'topp:states', 'TILED': true}
-  })
-});
-
-// assume features.json is a FeatureCollection in EPSG:4326
-var vector = new ol.layer.Vector({
-  source: new ol.source.Vector({
-    protocol: new ol.protocol.HTTP({
-      url: './data/features.json'
-    }),
-    parser: new ol.parser.GeoJSON()
-  })
-});
-
-var map = new ol.Map({
-  target: 'map',
-  layers: [raster, vector],
-  view: new ol.View2D({
-    projection: 'EPSG:1234',
-    center: ol.projection.transform(
-        new ol.Coordinate(139.7, 35.7), 'EPSG:4326', 'EPSG:1234'),
-    zoom: 9
-  })
-});
-```

-This alternative can be implemented if the layer knows the map projection.  The vector layer would be responsible for calling `source.protocol.read({success: callback})` where the callback would call `source.parser.parseFeatures(data, {projection: projection})` (`data` is supplied to the callback and `projection` comes from the map's view).  The layer would maintain a cache of features in the map view's projection, and these would be provided on demand to layer's the renderer.
