People, please, before suggesting alternatives to this GPS-Logger I found, do first check if the sources are available, and if the license allows us to work further on it. I am currently quite happy with the Qt interface in GPS-Logger, and I'm learning Qt, which I think is a good use of my time. I don't know how to make it read OSM tiles, and I don't know how to re-package it in a deb file, but these are two interesting things to learn, and the result would be something that can be reused by others.
