GEOGRAPHIC INFORMATION SYSTEMS - Introduction

On a rainy weekend during the school year, you decide to visit the science museum that has just opened near your home. When you arrive, you discover that it is huge. There are more interesting things to see than you can possibly examine in an afternoon. How do you decide what to see? How do you find out where to go?

Luckily, inside the entrance of the museum, you see a row of computer stations. At each station, a screen displays a map of the museum. As you move the computerís mouse over the map, a window appears telling you what is displayed in each area. You want to see the museumís exhibit on gemstones. You notice that the computer screen has a search command. You enter the word "gemstones". The screen responds by highlighting the room on the map where gemstones are displayed. It also tells you how to get there from the museum entrance, as well as what gemstones are currently on display.
