NAVTEQ MapTP MGI Service: Retrieving Bitmaps and Text Based Image Map Data
The MapTP MapGraphicsInterface (MGI) Service provides methods for requesting binary map images (bitmaps) and text based image map data (imap/csv). The MAPTP MGI Service renders raster maps (bitmaps) from vector data on the fly. The images generated by the MGI always refer to the current state of a MapTP session. This state depends on initial settings and modifications through MapTP Maplet Remote Control (MRC) commands. The main purpose of MGI is to return static information after interaction with the MapTP Web Services and without the need for an applet.
Two possible use cases:
-
Printing: The render engine produces high quality, anti-aliased maps of different scale and resolution measured in dots per inch (DPI). The map images can be produced in GIF, PNG or JPG format and can be used for Internet and mobile applications as well as for print media.
-
Static mapping clients: The MGI Service is also used for mapping applications on platforms where an implementation of the MapTP vector streaming technology is not available. Mobile devices without Java support are examples.
The MapTP MGI Web Service can be accessed via SOAP and HTTP GET.
Operations of the NAVTEQ MapTP MGI Service
The MapTP MGI Service provides the following operations for retrieving image data of the current map view:
- renderBitmapImage: Renders and returns a bitmap image.
- renderImageMap: Renders a bitmap image. The image itself is buffered on the server and can be retrieved with a ''getBufferedBitmapImage'' operation. This operation returns additional information about the image such as the bounds of the rendered map image.
- getBufferedBitmapImage: Returns the bitmap image that was rendered in a previous ''renderImageMap'' request.
SOAP Interface
The WSDL document for the MapTP MGI Web Service is for example available at:
http://maptp12.map24.com/map24/webservices1.5?soap=Map24RenderEngine
Note: The given server URL (maptp12.map24.com) is just an example. The actual server URL to use will be given to you when registering as a customer of MapTP products.
Examples
Example SOAP and HTTP GET requests are available here.
