AGU 2015 – Day 3 – Tiredness and Structure-from-Motion

It’s now the third day of the AGU 2015 and the tiredness starts to kick in, making the morning poster session a bit difficult and slow until the coffee break at 10:00. However after the caffeine reached my brain, my day started and I saw some pretty good things. Most of the day was dedicated to snow processes and remote sensing of the cryosphere so obviously there was a lot of Structure-from-Motion (SfM) studies.

One poster was combining the 2 subjects of the day: Phillip Harder (University of Saskatchewan) was displaying a study on how to use UAV, SfM and modelling to better understand snow depletion.

In the talk session of the afternoon, the 3 presentations which I think stranded out were:

  • Jessica Cherry talked about the cost of SfM vs traditional photogrammetry and how to take them into account before choosing a remote sensing solution.
  • Matt Nolan presented his work on measuring the elevation of some Alaskan mountains using SfM (http://www.fairbanksfodar.com)
  • Gabriel Wolken showed that is possible to measure snow depth with a very good accuracy on a vast domain using SfM.

I concluded my day with a drink at “the Thirsty Bear” bar with David Rounce, his supervisor Prof. McKinney and some other people that I can’t remember the name (sorry guys, too many people in this conference)!
