Wednesday I linked a few roads that don't appear yet on the vector version of the french land registry. That's roads near Rabouillet, Ille-sur-Têt, St Michel-de-Llotes, Néfiach and Millas in Pyrénées-Orientales, France.
I also made a blog post (in french) on how to create OSM Garmin maps with a Mac. I compiled information on how to retrieve data, make maps and tie them in a single file with mkgmap.
