17. Make a new blank map. Add as data Boat_SP83.shp. There is a dropdown menu besides the Add
Data button, which you probably haven't noticed. Click it. Click Add Basemap. Assuming you have
an Internet connection, you will see a dozen or so thumbnails of basemaps that are available
over the web, courtesy of Esri. Select National Geographic. Click Add. Wait. (If nothing shows up
after a few seconds, click the pan tool and move the map very slightly, to encourage the software
to create the display.) You will see topography (by means of shading) and some roads. Note
Interstate 75 for future reference. Type 50,000 in the scale box and then Pan, following I-75 north,
to Lexington. Find Lexington Reservoir No 4 to the west of I-75, as you begin to get into the more
developed area of Lexington. You could pan all the way to Toronto if you wanted to. This is a world-
wide basemap. Type 4,000,000 into the scale box. Find Lake Ontario and Toronto, Canada. At a
scale of 1:500,000 you can see that Toronto has an airport south of the city on an island in Lake
Ontario. At 1:25,000 you can read the name of the Toronto Airport. __________________________.
