gpsplot.py - A tiny program to plot GPS output

GPS data file

GNU plot

You can visualize it using GNU plot and the following commands:

$ gnuplot
gnuplot> set grid
gnuplot> unset logscale x
gnuplot> unset logscale y
gnuplot> set xlabel "Distance in km"
gnuplot> set ylabel "Height in m"
gnuplot> set terminal png
gnuplot> set output "track.png"
gnuplot> plot "gpsplot.gp" using 3:7 notitle with lines linetype 3

Then open track.png in your folder.

Limitations

You need to change file names in script. Also this doesn't work yet if a time difference between two data points is more than 24h. Other than that have fun!
