I just added a 'points' option to the arc filter, so you can filter on distance from the vertices instead of on distance from the lines between them. One thing that'll be useful for is taking a whole state full of caches and filtering it down to just the caches that are within, say, 20 miles of one or more of your favorite spots. Just throw all of your favorite spots in an arc-formatted text file and do this: gpsbabel -i gpx -f indiana.gpx \ -x arc,file=favorites.txt,points,distance=20m \ -o xmap,prefer_shortnames -F nearby.txt Of course, it'd also be useful if you had, say, a collection of Interstate exits, rest areas, or what-have-you. Note that this functionality is not in the currently downloadable build of GPSBabel, so it might not be useful for your talk. (In other non-tip-or-trick news, I also consolidated all of the conversions from radians to miles and updated them to use the WGS84 value for the earth's radius.) |
