genurl option

Generate file with lat/lon for centering map.

genurl is a convenience option for generating the scaling paramaters 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.

For example:

gpsbabel -i geo -f geocaching.loc -o tiger,genurl=tiger.ctr -F tiger.dat

may create tiger.ctr with

lat=36.042108&lon=-86.877408&ht=0.161172&wid=0.591771&iwd=768&iht=768

After uploading tiger.dat to a public server, a request to

http://tiger.census.gov/cgi-bin/mapgen?murl=$THATFILE$(cat tiger.ctr)

will return a gif file from the tiger server that's suitably scaled.

margin option

Margin for map. Degrees or percentage.

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.

This option is most useful for ensuring there is adaequate space for the label around the markers when

generating automatically scaled maps.

snlen option

Max shortname length when used with -s.

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.

oldthresh option

Days after which points are considered old.

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 'old-

marker' option).

oldmarker option

Marker type for old points.
