Changing the Base Map

You can add map datasets, such as XMap USA Street Level Data and USA Topographic

Data, to XMap using the Base Data feature. Click the Map Data tab, click Data, and then

click Base Data. Then add the path where the data is stored on your system. Once a data-

set has been added to base data, it is automatically loaded in all other projects.

By default, the DVD drive on your computer is a base data location. Also, any compatible

datasets that you have saved to your hard drive since you installed XMap should display in

the Base Data locations list.

Changing the Map View to Show a Single Map or a Split Map

Use the split-window in XMap to view two maps at the same time.

Youcanaccesstheleft(secondary)mapbyslidingthedividerbarthatrunsperpendicular

to the tab area. When you move the bar all the way to the left of the map, only the primary

map displays. When you move the bar all the way to the right, only the secondary map

displays. Drag the divider bar to adjust the display areas of the primary and secondary

maps.
