    • Survey design
    • Collect GPS/GNSS ground control points
    • Collect photos via UAV (uncrewed aerial vehicle)
    • Deliverables – SfM photos (on UAV), ground control points (via Emlids), variety of GPS points for more profiles/topography profiles, field notes, reflections on implications for teaching
    • TAKE group photo
  • 5:00 pm - Return to campus/dorms
  • 6:30 pm – Dinner at Ben's house

Monday May 23 - Change detection and start implementation planning

  • 7:15 am - Breakfast buffet near classroom
  • 8:00 am – MetaShape continued; Getting started with change detection
    • Make SfM point clouds from photos taken at Sunday's field site
    • Break as needed
    • Change detection with CloudCompare
      • Including M3C2 plugin - which allows you to surface-normal change (not just, say, vertical change)
      • More typically DEMs only allow you to look at change in one of the cardinal directions
  • 12:00 pm - Lunch
  • 1:00 pm – More on GPS and Starting Implementation Planning [mostly Beth]
    • Continue a bit on software from the morning if needed
    • Post-processing kinematic and NTRIP (non-RTK options); also troubleshooting FIX issues

      Accessing GPS/GNSS Field Equipment and Support
    • Field teaching case studies (including DEI and accessibility considerations) [leaders, plus any participants who can contribute]
    • Break when it makes sense
    • Start implementation planning for teaching
      • Participant Implementation Workspaces - Record ideas in the workspace under your name (Yesenia and Nina are grouped with Anita and MikeM, respectively)
      • Brief survey about initial field teaching ideas (to help us divide up breakout groups for Tuesday)
        Please do this (very) short survey by 5:00 pm TODAY
      • HOMEWORK
        • First thing Tuesday be ready to share initial plans with breakout group (opt. 2-5 slides shown on your laptop) – aim for ~5 minutes of sharing
