Support for the "Garmin GPS Database" format used by default in MapSource™ versions since release 6.0 of that product. By default GPSBabel creates gdb files of version 2. Version 2 is used in Mapsource 6.3 and 6.5.
Garmin GPS database is an undocumented file format. The basic info for this module came from the existing MapSource conversion code.
Default category on output (1..16).
This option specifies the default category for gdb output. It should be a number from 1 to 16.
Version of gdb file to generate (1..3).
This option specifies the data format version for the output file. Version 2 is the default. Currently, the only other valid values for this option are 1 and 3.
Drop route points that do not have an equivalent waypoint (hidden points).
This option instructs GPSBabel to drop hidden (calculated) points from routes.
Include major turn points (with description) from calculated route.
If this option is specified, GPSBabel drops all calculated route points,
with exception of points with a description (i.e. "Make U-turns until you know where you are.").
The priority of this option is higher than of the via
option.
A value of 1 or y overwrites the via
settings.
Example 3.1. Using gdb option roadbook
to create simple html roadbook
gpsbabel -i gdb,roadbook -f sample.gdb -x nuketypes,waypoints,tracks -x transform,wpt=rte -o html -F roadbook.html
Because gdb creates internal a route AND a waypoint list, you have to drop all waypoints and transform the route into waypoints. So you'll get a well ordered html output. We sugess these steps for all waypoint-only formats as html.
