I created this data with a Garmin 64st.

while driving I used a 1 second interval

while hiking I tried to change it to 3-5 seconds (if I remembered). The ferry from Paquera to Puntarenas I believe i did every 8-10 seconds.

I also saved my tracks with a Olympus Stylus TG-2. This data is pretty rough though (but there is one line when we went white water rafting that shows the river that I did not bring my GPS on).

I release this data to the public domain – you may use for any purpose.
