Option 1

Write a Processing program using Eitan M.'s example, and the ones available on the Class Web page illustrating how to access Web pages (php pages) to put together a Processing applet that displays two different KML files. The selection of the KML files is done via the URL request, inside the Processing program. The way I recommend implementing this is to append a request at the end of the URL of your php page of the form "?Id=3,4". In this particular example, it would indicate that the php program has to return the contents (filtered or not) of the KML files with Ids 3 and 4.

Option 2

Write a Processing applet that contains the same elements (box, buttons, widgets) as the form you created in a previous assignment, where you specify which KML file should be selected depending on various parameters. In this case you need to display only one KML file.
