<title>Recommended Programs</title>
<formalpara><title>gpsbabel</title>
<para>&appname; uses &gpsbabel; for several important functions, such as:</para>
</formalpara>
<itemizedlist>
<listitem><para>Importing Files from many formats (including KML)</para></listitem>
<listitem><para>Exporting Files to various formats</para></listitem>
<listitem><para>Transfer Data to/from GPS Devices via serial connections</para></listitem>
</itemizedlist>
<para>Thus these will not be available if the program can not be found.</para>
<para>For <trademark>Unix</trademark> like systems this will search the system path to find the program, as it is typically installed via the System's package manager.</para>
<para>
From &appname; 1.6 onwards &gpsbabel; is not deployed automatically on <trademark>Windows</trademark> systems.
If &gpsbabel; is not installed in a typical <trademark>Windows</trademark> location that &appname; can find,
then the &gpsbabel; preference can be set to specify the exact location. See <xref linkend="prefs_external"/>.
</para>
<para>&appname; will need to be restarted to use the new &gpsbabel; location preference.</para>
<formalpara><title>unbuffer</title>
<para>&appname; uses unbuffer command to optimize conversion calls.</para>
</formalpara>
<para>This mainly applies to <trademark>Unix</trademark> like systems when invoking &gpsbabel; commands.</para>
<formalpara><title>gpsd (not available for <trademark>Windows</trademark>)</title>
<para>&appname; can use <ulink url="https://gpsd.gitlab.io/gpsd">gpsd</ulink> to get the current location.</para>
</formalpara>
<formalpara><title>togpx</title>
<para>&appname; will use <ulink url="https://github.com/tyrasd/togpx">togpx</ulink> to open GeoJSON files if the program is available on the system.</para>
</formalpara>
<formalpara><title>togeojson</title>
<para>&appname; will use <ulink url="https://github.com/mapbox/togeojson">togeojson</ulink> to export to GeoJSON files if the program is available on the system.</para>
