I just discovered openstreetmap before going on holliday to Elnido, so I decided to bring my laptop and GPS to follow the progression of my bus trip from the airport to Elnido.
GPS maps and good maps in general are relatively rare here in the Philippines, and openstreetmap is a great alternative.
Unfortunately the roads in Palawan were not so accurately mapped (traced from Yahoo ?).
Back home, I started correcting the roads I used and logged. I'm done just now...one month later. Wow this is really addictive...
