MapData
MapData Overview
The MapData tab in Topo USA 4.0 lets you manage the type of data you view on your maps and save
separate views of your maps.
The following list describes the functions that are available in the MapData tab.
Save all of the work that you have done as a single file so you can open it again later. These saved
workspaces are called projects.
Create various map views and save each one in a different project, if desired. In this way, you can
save separate views of often-viewed areas at your preferred zoom level and other settings.
Open projects as you need them to view and/or edit. Save any desired changes.
What Is a Project?
A project consists of currently viewed datasets, the map center coordinates, the current zoom level, the
current magnification, preferences, and any routes and draw files you have added to it.
As you create routes and draw files, they are added to the currently selected project file, which are saved
by default in C:\DeLorme Docs\Projects.
Each associated file is saved in its respective folder in the C:\DeLorme Docs directory. For example, a
draw file is saved in C:\DeLorme Docs\Draw. For more information about the DeLorme Docs directory,
see Topo USA 4.0 File Directories on page 10.
How Do I View Multiple Datasets With One CD-ROM Drive?
Most users do not have more than one CD-ROM drive on their computer. Users with one CD-ROM drive
who want to view multiple types of data in Topo USA 4.0 can do so by saving at least one dataset to their
hard disk drive. Some datasets can be installed by running setup.exe on the disc. However, some discs do
not offer an installation utility and must be saved on your hard disk drive using Windows
®
Explorer or
other file management tools. Data that is manually copied to your hard disk drive must be referenced
using the Locations feature in Topo USA 4.0. Locations keeps track of all datasets that have been
installed on your system. If you want to view a dataset in Topo USA (such as 3-D TopoQuads
®
), you can
use the Locations feature to add the data to the program. For more information, see Transferring Map
Data Locations on page 55.
What is Exchange?
If you click the Data button and then click Exchange, the Exchange wizard displays. The Exchange
wizard allows you to exchange the selected data file with a GPS device.
Note: You can also launch the Exchange wizard using the Exchange button on the GPS tab. For more
information, see Uploading to a GPS Receiver on page 115 or Downloading from a GPS Receiver on
page 115.
Can I Reuse Draw Files and Routes in Other Projects?
After creating routes and draw files, you may not want to do all this work again for another project. You
can share routes and draw files between projects by clicking the Data button and then clicking Add on
the shortcut menu.
