This format is described at: <a class="ulink" href="http://tiger.census.gov/instruct.html" target="_top">tiger.census.gov</a>.
Do notice that this format is not the actual Tiger line mapping
records, but rather the interface to their online mapping
program.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_nolabels"></a><code class="option">nolabels</code> option</h3></div></div></div><p>
      Suppress labels on generated pins.
    </p><p>This option tells GPSBabel to not generate labels on the pins.   If
this is true, the description of the incoming waypoints are ignored and not
placed on the pins.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_genurl"></a><code class="option">genurl</code> option</h3></div></div></div><p>
      Generate file with lat/lon for centering map.
    </p><p>
genurl is a convenience option for generating the scaling parameters
when accessing the Tiger servers.  It will output the latitude, longitude,
height, and width parameters in a form suitable for use in the URL to generate
a map that will hold all the points to be displayed  and is suitably scaled
and centered.   
</p><p>For example:</p><p><strong class="userinput"><code>gpsbabel -i geo -f geocaching.loc -o tiger,genurl=tiger.ctr -F tiger.dat</code></strong></p><p>
may create tiger.ctr with
</p><pre class="screen">
lat=36.042108&amp;lon=-86.877408&amp;ht=0.161172&amp;wid=0.591771&amp;iwd=768&amp;iht=768</pre><p>

After uploading tiger.dat to a public server, a request to 
</p><pre class="screen"> http://tiger.census.gov/cgi-bin/mapgen?murl=$THATFILE$(cat tiger.ctr)</pre><p>
will return a gif file from the tiger server that's suitably scaled.

</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_margin"></a><code class="option">margin</code> option</h3></div></div></div><p>
      Margin for map.  Degrees or percentage.
    </p><p>This option specifies a margin around the maps for the genurl options.
The margin may be specified in either decimal degrees or as a 
percentage.</p><p>
This option is most useful for ensuring there is adequate space for
the label around the markers when generating automatically scaled maps.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_snlen"></a><code class="option">snlen</code> option</h3></div></div></div><p>
      Max shortname length when used with -s.
    </p><p>
The snlen option controls the maximum length of names generated by the '-s'
option.  It's particularly useful in Tiger maps to avoid the amount of clutter
generated by potentially lengthy labels on the markers.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_oldthresh"></a><code class="option">oldthresh</code> option</h3></div></div></div><p>
      Days after which points are considered old.
    </p><p>This options allows you to control the threshold in days between
whether a pin is considered "new" (and thus potentially governed by the
'newmarker' option) or "old" (and thus potentially governed by the 
'oldmarker' option).
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_oldmarker"></a><code class="option">oldmarker</code> option</h3></div></div></div><p>
      Marker type for old points.
    </p><p>This option specifies the pin to be used if a waypoint has a creation
time newer than 'oldthresh' days.</p><p>The default is "redpin".</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_newmarker"></a><code class="option">newmarker</code> option</h3></div></div></div><p>
      Marker type for new points.
    </p><p>This option specifies the pin to be used if a waypoint has a creation
time older than 'oldthresh' days.</p><p>The default is "greenpin".</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_suppresswhite"></a><code class="option">suppresswhite</code> option</h3></div></div></div><p>
      Suppress whitespace in generated shortnames.
    </p><p>
When set, this options tells the '-s' smartname generator to not allow 
any spaces in the labels generated for markers.
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_unfoundmarker"></a><code class="option">unfoundmarker</code> option</h3></div></div></div><p>
      Marker type for unfound points.
    </p><p> 
  Specifies the icon type for unfound geocaches.  Default is "bluepin".
</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_xpixels"></a><code class="option">xpixels</code> option</h3></div></div></div><p>
      Width in pixels of map.
    </p><p>The xpixels argument lets you specify the number of pixels to be
generated by the Tiger server along the horizontal axis when using the 
'genurl' option.  </p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_ypixels"></a><code class="option">ypixels</code> option</h3></div></div></div><p>
      Height in pixels of map.
    </p><p>The ypixels argument lets you specify the number of pixels to be
generated by the Tiger server along the vertical axis when using the
'genurl' option.  </p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_tiger_o_iconismarker"></a><code class="option">iconismarker</code> option</h3></div></div></div><p>
      The icon description is already the marker.
    </p><p> This options signifies that the icon in the incoming format is to be used
without change in the generated Tiger output file.  Without this option,
GPSBabel tries to color pins based on their creation time and certain 
Geocaching traits when available.</p></div></div><div xmlns="http://www.w3.org/1999/xhtml" class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="fmt_dmtlog.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="The_Formats.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="fmt_unicsv.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">TrackLogs digital mapping (.trl) (dmtlog) </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Universal csv with field structure in first line (unicsv)</td></tr></table></div>
