I am looking for ways to programmatically convert my GPS logs into images and would like to do it in Ruby ... if this is an acceptable tool. I don't have a GIS background, but as a programmer, I think this is an interesting problem.
Here is what I have come up with so far. First you need some kind of graphics library. I set off gnuplot because I found Ruby binding for this, but R seems to be hot these days. I created a small script that converts a GPX file and transfers the data to gnuplot, which leads to something like this: alt text http://dl.dropbox.com/u/45672/gpslog.png
It looks great, but gnuplot seems really a tool for creating graphs, not spatial data. Is this a way to do this or are there much better solutions?
Here is another example , any idea how you create such things?
