Off-Road Navigation with GPS Fugawi Global Navigator 3.3.1(5)
By admin | May 15, 2007
Be careful how much you zoom in, however, since the maps are raster versions and if you get in too close, they will become pixelized beyond usefulness.
Figure 8: Excessive zooming in can render the map useless, since the graphics are not ’scaled’ but simply bitmap pictures of the original map.
The top left of the screen provides information on current speed and heading. In the right top is the current map scale, an indicator of whether the GPS unit has a ‘fix’ yet, and whether the GPS port is open (the P in a circle in the top right). Along the bottom is the menu system, then icons for toggling centering of the map on the current GPS position on and off, accessing the GPS information screens, and turning Tracking on and off.
The PDA version of the application basically provides the ability to track current location, mark waypoints, create a route of waypoints, and follow a route. You can also download routes and waypoints from those created/managed on the PC version None of the fun stuff like 3-D rendering and flythough based on elevation data is available.
The main difference between this and a road-based GPS application is that you really can’t ask GN “How do I get there?” because it will simply draw a straight line between you and destination, regardless of the terrain. Even using the street map overlay, Global Navigator is unaware of the use of streets as preferred routes for travel.
This application is most useful for back-tracking to the starting point when out on a hike (using the tracking function) or following a route predefined by you or supplied by others. The tracking function allows the application to mark your route as you travel, by recording your current position at regular intervals as you hike (or ride) along.
