I’ve been playing around with a lot of time lapse ideas lately. I took some pictures for part of the return trip from Potholes which you’ll see soon, but on the hike up to Muir, I distracted myself by thinking how I could combine all the various data I had collected into one display.
In the backpack, the GPS was taking a recording every few seconds. I was also snapping photos every once in a while. To combine the two, I wrote an app to plot out our current location on top of a topo map and show a photo that was taken at that time (if one exists.) With the GPS data, I was also able to show our rate of ascent, the current elevation, the current time, and the latitude and longitude.
I combined that all into one application, wrote each update out to a new image file and then combined the image files into a movie file. It’s embedded below or you can find it on YouTube. It’s best when viewed in HD in full screen mode.
