The input comes in the form of [http://en.wikipedia.org/wiki/XML XML] [http://www.cs.umd.edu/users/meesh/420/spr07/part1/p11/node19.html]; a handy [https://www.cs.umd.edu/users/meesh/420/ProjectBook/cmsc420util.jar XmlUtility] for parsing the input is provided.

If you are not familiar with XML, w3schools has a great tutorial that can be found [http://www.w3schools.com/xml/ here]. The spec also has a decent amount of information on how to parse the XML.

== Output ==
Output is stored in a DOM object that represents an XML file. A DOM document consists of a root Element that has any number of child Elements, each of which can have any number of child Elements. The DOM document building is handled by [http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html org.wc3.dom.Document]. When required to print [http://en.wikipedia.org/wiki/XML XML] for output, you can use the same handy [http://wam.umd.edu/~bzoller/cmsc420/doc/cmsc420/xml/XmlUtility.html XmlUtility] [http://www.cs.umd.edu/users/meesh/420/spr07/part1/p11/node21.html].

You will want to create a <code>City</code> object to store basic information about cities; the spec recommends extending <code>[http://java.sun.com/j2se/1.5.0/docs/api/java/awt/geom/Point2D.Float.html java.awt.geom.Point2D.Float]</code> [http://www.cs.umd.edu/users/meesh/420/spr07/part1/p11/node23.html].

Since this is a visual project, it will help to be able to visualize your data structures. A nice graphics library called [http://wam.umd.edu/~bzoller/cmsc420/doc/cmsc420/drawing/CanvasPlus.html CanvasPlus] [http://www.cs.umd.edu/users/meesh/420/spr07/part1/p11/node24.html] makes this visualization easy.
