The tutorials are all based on the MVDEMO sample data set (available from the map visualization component page on the Oracle Technology Network) and assume a data source named mvdemo. The tutorials start with the basics (display a map tile layer, add a navigation panel, display interactive features and information windows) and move on to more complex topics such as registering event listeners, programmatically creating and using styles, and spatial filtering. Tutorials and demos for the API are available as a standalone packaged application with the root context path /mvdemo. For detailed information about all classes in the Oracle Maps JavaScript API ), see the Javadoc-style reference documentation, which is included in the mvdemo.ear file and is available at the following location: host:port /mvdemo/api/oracle_maps_html5_api.jsp To access these functions, use the JavaScript API, which consists of several JavaScript classes. (Redline drawings are often rendered in red, although you can specify a line style that uses any color.) Redlining refers to the application user creating a polygon or polyline by clicking the mouse button and then moving the mouse and clicking multiple times, with each click extending the redline by a straight line. But there is no issue of label repition.The Oracle Maps JavaScript client is a browser-based map visualization engine that works on top of the map tile server and that uses HTML5 technology.įetching map tiles from the map tile server and displaying them as a map tile layer in the web browser.Ĭontrolling user interaction, such as dragging for map navigation, clicking features, drawing rectangles, and redlining.ĭrawing a rectangle refers to the application user creating a rectangle by clicking and holding the mouse button at one corner of the rectangle, dragging the mouse to the diagonally opposite corner, and releasing the mouse button. For example, the tile at zoom level 5, x=15, y=10, should cover these bounds: You need to calculate the appropriate parameters to pass to your service to get each tile. Return new Uri(String.Format(this.UriFormat, zoomLevel, x, y )) īing Maps will insert the parameters into the tile request to get the right tile. pngĪs your base URL template, then in your getUri() method: These are stored using the URL syntax zoomlevel / x / y. The GetUri() method requests different tiles by inserting the requested tile x, y, and zoom level into this template, but as there's no placeholders for it to do so, instead you're just getting the same tile returned each time.įor example, suppose that you wanted to create a tile layer based on the OpenStreetMap tile server. Your GeorServerSource class appears to state a hardcoded URL to one particular tile. Note: Is this becuase we extend the class as TileSource? Is therey any UnTileSource for bing map? Return new Uri(String.Format(this.UriFormat, x, y, zoomLevel)) Public override Uri GetUri(int x, int y, int zoomLevel)
It seems only a single tile of map is repeatedly shown by bing map Recently while trying to display a wms map using bing map control, It is found that the map is not rendered
