A map scale is displayed on the bottom of the window and a status line provides information about print scales, and system events. A 1,000

Moving the Map Around the Screen
You can use the arrow keys and the scroll bar handles to move the map around your screen.
Press the shift key and the mouse cursor changes to a hand
that you can use to drag the
map around the screen.
Double click on any map location to bring the location to the screen center. Double
click on a map border to move to an adjacent map.
Setting the Map Scale
Zoom in using the PageDn key (moves the helicopter down). Zoom-Out using the PageUp key
(moves the helicopter up). Use the Zoom box to directly set the scale, or use a hot key
(Alt-1 100%, Alt-2 200%..).
The resulting map scale depends upon the size of a pixel on your monitor. The 'File:
Setup Printer, Map Scale' selection allows you to accurately control the resulting printed
map scale. Your map viewing window will be adjusted to match the aspect ratio of your
printer so that 'what you see, will be what you get' on the printed output. (See
also Tour 9: Printing Maps).
Map Resolution
1:24,000 scale maps are stored at 160 DPI resolution. This results in each displayed
pixel representing 3.81 square meters of area. (Alaskan 1:24,000 scale maps are
stored at 250 DPI.)
1:100,000 scale maps are
stored at 250 dpi resolution which results in 10.61 meters per pixel.
1:250,000 scale maps are stored at 250
DPI resolution which results in 25.4 square meters per pixel.
These two maps show the same
location at these two scales:
1:24,000 Scale: The confluence of the Yampa and Green Rivers
1:250,000 Scale: The confluence of the Yampa and Green Rivers
