Using JAK and Google Geocoder

In a previous post I mentioned that I would be doing some experimenting with the JAK - Java API for KML. I have now created a simple program that creates a KML file using co-ordinates obtained from calling the Google Geocoder.

If you wish to review the whole program I have made it available here (4mb).

The main parts of the code are as follows:

GeoCoder class

• converts a street address into a longitude/latitude point.
• call getLocation method with a string representing the address.
• class uses Google Geocoder.

Refer to the Geocoder.java class file in the download for more information on how this works.



Main Class

• assigns an address from the first command line argument
  

view source

print?

1	address = args[0];

• calls the GeoCoder.getLocation method with Address String
  

view source

print?

1	location = Geocoder.getLocation(address).toString();

• creates a KML file using the location value returned by the GeoCoder class
  

view source

print?

01	final Kml kml = new Kml();

02	kml.createAndSetPlacemark()

03	.withName(address)

04	.withOpen(Boolean.TRUE)

05	.createAndSetPoint()

06	.addToCoordinates(location);

07

08

try {

09	kml.marshal(new File("HelloKml.kml"));

10	} catch (FileNotFoundException ex) {

11	Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);

12

}

In the future I will expand on this application to provide more information in the KML.
