Leandro, Stefan's advice on using an iterative development process was excellent. If I remember correctly the original goal for this project was to allow the user to develop a graphical model for data processing.
So I will take this a step further than Stefan. Pick just ONE or TWO vector layer processing operations. These may be operations that are already implemented in OpenJUMP that we can extract, or they may be new operations. This will be your first module. If you decide to go with new operations I can help you access the OpenJUMP and JTS API. Then we need to construct the user interface that allows the user to construct the graphical model for processing. This could get really ugly, really fast, because of the potential complexity. So I think we start by making the user interface very constrained. Let's used a fixed grid. We can have a button or list that allows the user to assign a single input to the grid (this will be an OpenJUMP Layer), and then a single vector operation (one of the ones you create in your first modue). I am starting to get a little nervous, and I don't want to bite of more than you can chew. Your next assignment: Choose one or two vector operations that we can allow the user to add to the graphical model. The simpler these operations the better. I will poke around on the net to see if there is an existing Swing grid component that we can use. The Sunburned Surveyor OpenJUMP Developers: I imagine we will want to encapsulate the "vector operation" as an interface. Do we have an existing interface kicking around in JTS/deegree/GeoTools that can be used for this purpose?
