From the back: In the years 420 and 1065, the Imperial Interstellar Scout Service published the First and Second Grand Surveys. Some of their methods, and some of the results of their surveys, have been published before. But now, with the brand-new, state-of-the-art material in this book, you can have all the detail you ever wanted. If you already use Scouts, Grand Survey continues where Scouts left off. And if you don't use Scouts, you can still use Grand Survey to learn more about a world. Starting with the basic Traveller UPP for the world, Grand Survey leads you step-by-step to detailed physical characteristics and an accurate map of the world. Whether you're a Traveller player or a referee, Grand Survey tells you what you want to know when you arrive at a new world.
