These are 'deckplans' for the 2 most basic types of starport in Traveller. The pdf contains background information and details of the facilities available. Another 5 pages contain details of sample npc's from the various departments.
There are seperate deckplans for various parts of the starport in black & white, which are clear & crisp with a square grid ideal for minatures. I would have liked colour plans, so have rated this as a 4 rather than a 5.
The product is excellent value for money.
