10.6 GpsDrive

GpsDrive
(http://www.gpsdrive.cc/index.shtml) is an
open source GPS-aware navigation system that uses
GTK+. It works with
maps from a variety of sources, and plot waypoints, and even lets you
share your position with friends and send SMS text messages with
position information.

If you launch GpsDrive while GPSd is listening on the localhost, it
will pick it up and start reading coordinates from it. By default,
GpsDrive displays a placeholder map that's not very
detailed (see Figure 10-9). However, you can
download new maps by clicking the Download Map button and selecting
the map server from the dialog that pops up, as shown in Figure 10-10.

Using GpsDrive to download maps from a commercial map service may violate that site's Terms of Service (ToS). Be sure to consult that mapping site's ToS before proceeding.

The latest beta version as of this writing (2.08pre12) comes with
support for NASA's Blue Marble
(http://earthobservatory.nasa.gov/Newsroom/BlueMarble/)
satellite images. You must download some extremely large files (over
1 GB uncompressed) and install them according to the
README.nasamaps file that's
included with the GpsDrive distribution. Figure 10-11
shows the NASA maps in action.

GpsDrive does not support route planning, but it does show your
speed, position, and altitude. What's more, a
version is available that runs on Linux-powered handhelds
(http://www.gpsdrive.cc/pda.shtml), so you can
load it up with waypoints for points of interest and use it while you
wander around unfamiliar territory.
