DESCRIPTION:At the last minute\, I packed my drone for a trip to the CUCC A
 ustria Expedition to the Loser Plateau. Loser is a very large limestone pl
 ateau at 2\,000 meters\, so the vegetation is mostly a low scrub pine. Thi
 s creates an ideal environment for using drones to aid prospecting for new
  potential entrances. This talk covers the speaker's crash course in photo
 grammetry to create useful imagery and models from drone flights.
