Using GPS
GPS Overview
You can take advantage of the Global Positioning System (GPS) through an interface
with most GPS receivers, such as DeLorme Earthmate devices.
Using your DeLorme application, a portable computer, and your GPS receiver, you
can display a "bread crumb trail" to track your progress as you travel.
You have two ways to use GPS in your mapping application:
• NavMode–This is the default GPS view—a hands free full-screen view that
you can display in 2-D or 3-D. By default, the Control Panel is hidden and the
tabs are minimized; however, you can change your display options.
• GPS tab view–This option allows you to use the GPS tab to control
navigating and tracking. By default, the tabs and Control Panel are visible,
but you can opt to hide them. It is available only in 2-D mode.
To turn NavMode on or off, click the NavMode
button on the toolbar. When the
button appears indented
NavMode is on.
Note The button is greyed out
unless you have a GPS device plugged in or are
playing back a GPS log file.
You can also change your GPS view in the Options dialog box:
1. Click the Options button
on the toolbar and click the GPS tab.
You can also click the Options button
on the GPS tab.
2. Clear the Use NavMode check box to turn it off, or select the check box to
turn it on.
3. Click OK.
DeLorme software interfaces with different GPS devices as outlined below.
• DeLorme GPS Devices: DeLorme GPS devices will interface with a current
DeLorme software release.
• USB GPS Support: DeLorme software can use the data output from a USB
GPS if the device meets one of the following criteria:
• When the GPS is attached to the computer, it is recognized and
displayed under Ports in the Microsoft Windows Device Manager.
• The unit is a GARMIN USB device and the GARMIN drivers are
installed.
Note Magellan USB devices are not currently supported.
• Serial GPS Support: DeLorme software can use the data output from a serial
GPS device. The device must be connected to a free COM port and output a
generic NMEA (National Marine Electronics Association) stream.
• Bluetooth GPS Support: DeLorme software can use the data output from a
Bluetooth GPS device. You must configure your Bluetooth software to create a
virtual serial port.
