Oracle Maps example - GeoRSS support

Instructions

This demo shows the basic support for displaying data from a GeoRSS feed. To achieve this, all you need to do is create a theme-based FOI layer, and provide the URL of the GeoRSS feed with a special prefix string "__georss__" as the name of the MapViewer theme. For instance, typicall you create a theme-based FOI layer based on a predefined mapviewer theme such as "customers" in this manner: 
  var themebasedfoi = new MVThemeBasedFOI('themebasedfoi1', 'mvdemo.customers');
To display the data from a GeoRSS accessible at the url 'http://foo.com/georss.xml', you will create the theme-based FOI layer like this: 
  
    var georss="mvdemo.__georss__http://foo.com/georss.xml";
    var themebasedfoi = new MVThemeBasedFOI('themebasedfoi1',georss);
That's all you need to do to display the geographic data or items in the GeoRSS feed. Note that typically MapViewer will render the geo-features in a GeoRSS feed using the default (gray) style. If you want to use a different style simply supply a MapViewer style name and set it on the theme-based FOI layer through MVThemeBasedFOI.setRenderingStyle().
Dont'f forget to specify proper web proxy info in the MapViewer's config file if you are running MapViewer inside a firewall and the GeoRSS feed comes from an external source.

For more information about GeoRSS, please check the GeoRSS web site, http://www.georss.org. MapViewer supports both Atom and RSS 1 or 2 feeds. For the detailed information regarding MapViewer's support of GeoRSS, please check the MapViewer User's Guide.

Here is the sample GeoRSS xml file that is used for this demo.

Source code

Here is the JavaScript code for the above map. 
  var mapview;
  
  function on_load_mapview() 
  {	
    var baseURL  = "http://"+document.location.host+"/mapviewer";
    var mapCenterLon = -122.45;
    var mapCenterLat =  37.7706;
    var mapZoom      =  4;       
    var mpoint = MVSdoGeometry.createPoint(mapCenterLon,mapCenterLat,8307);
    mapview = new MVMapView(document.getElementById("map"), baseURL);
    mapview.addMapTileLayer(new MVMapTileLayer("mvdemo.demo_map"));   
    mapview.setCenter(mpoint);   
    mapview.setZoomLevel(mapZoom);    
    
    var georss="mvdemo.__georss__"+baseURL+"/fsmc/tutorial/samples/georss.xml";
    var themebasedfoi = new MVThemeBasedFOI('themebasedfoi1',georss);
    
    
    themebasedfoi.setBringToTopOnMouseOver(true);
    mapview.addThemeBasedFOI(themebasedfoi);
    mapview.display();
  }
