We mostly used Google Street View to guesstimate where to put things. We started off building a 1/3 scale model of Gampel Pavilion (the stadium where commencement takes place), then we expanded on the roads around Gampel and started on the buildings connected to those roads. There are a variety of console commands (like /fill) that enable you to basically cut and paste portions of the world, so we could start building something in an open area and then transfer it to where it belonged once it was done.
