One of the most important capabilities of the IInformationTree5 interface is to provide a means of traversing the TerraExplorer Information Tree. This, in conjunction with other features, is a very powerful tool that can be used to achieve many different goals. For example, the client can traverse the tree and change the color for all or a subset of the objects. You can also use this method to present the project’s content in another format. Traversing the tree might also be used to search items in the project that match a set of criteria (i.e. all the models that are in a certain area on the terrain). You can even delete objects from the project using the IInformationTree3::DeleteItem() method.
