Today was environmental orientation day. Saturday classes were cancelled, and instead, students got to choose from a variety of activities that would get them outdoors and exploring the environment. I decided to do an activity where we used smartphones and Google Earth to map the trails around campus. I was pretty impressed by how far software has come in this area. Mapping was as easy as pressing a button on Trail Tracker, and then emailing the KML datafile for me to add to Google Earth.
