I see you've found my prized possession, my GIS computer. GIS stands for Geographic Information System. People that work for the city use GIS when they plan new roads, phone lines, electric wires, and buildings. I made this computer out of old parts that got washed down into the storm drains. You'll be able to see where you climbed down the manhole, where we are now, and where the sewer ends at Field's Point Treatment Plant.
Maps appear on the screen.
Rima consults user when each map loads up. There are four in all that display sewer data in the form of blue lines, or that are aerial photographs of downtown Providence. Landmarks are labeled on the maps. Kid can click and drag on the map to pan. Pushing the arrow keys causes other maps to appear.
