An aerial view of southeast Oxford, England. In the foreground is the Oxford Science Park, a high-tech industrial estate, focusing on biotechnology and computer hardware and software. Key to its success are the good transport network (notice the roads), the availability of land (this is a green-field site on the edge of town), and the association with Oxford University. In the background, the 1950s housing development of Rose Hill is clear, with the houses laid out in a geometric pattern.
