Dr. Adam SteerA couple of years ago I was invited to a UiT (University of the Arctic in Tromsø) outreach day about coastal ecology. I did a practical session about drones and made this map!How did I get unlicensed pilots to make a drone map in a no fly zone? They walked a flight pattern in teams, holding the drone up high - while a "pilot" directed them and pressed the shutter button! It was processed in time to show results at the end of the day :)<a href="https://mapstodon.space/tags/dronemapping" class="mention hashtag" rel="nofollow noopener" target="_blank">#dronemapping</a> <a href="https://mapstodon.space/tags/coastalEcology" class="mention hashtag" rel="nofollow noopener" target="_blank">#coastalEcology</a> <a href="https://mapstodon.space/tags/coastalMorphology" class="mention hashtag" rel="nofollow noopener" target="_blank">#coastalMorphology</a>

Dr. Adam SteerIt's been a while since the writing energy has hit. So today has been all about punching through a writeup of doing something useful with imperfect data<a href="https://mapstodon.space/tags/dronemapping" class="mention hashtag" rel="nofollow noopener" target="_blank">#dronemapping</a> <a href="https://mapstodon.space/tags/fieldwork" class="mention hashtag" rel="nofollow noopener" target="_blank">#fieldwork</a> <a href="https://mapstodon.space/tags/FOSS4G" class="mention hashtag" rel="nofollow noopener" target="_blank">#FOSS4G</a><a href="https://www.spatialised.net/counting-trees-in-sparse-woodland-with-opendronemap-pdal-and-qgis/" rel="nofollow noopener" translate="no" target="_blank">https://www.spatialised.net/counting-trees-in-sparse-woodland-with-opendronemap-pdal-and-qgis/</a>

Adam SteerThis is one of the worst <a href="https://pixelfed.social/discover/tags/DroneMaps?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#DroneMaps</a> I've ever made, and is also incredibly valuable because it is data that will never be captured again, plus it really helps get another dataset - the electromagnetic induction ridge survey line - into context. It was about -12C, with 12m/s winds, 82 degrees north (in this map, north is to the right). I launched the drone with a snow shovel as a windshield against blowing /saltating snow at ground level, and at the first launch the aircraft promptly blew away and crashed in the snow. On recovery the drone was undamaged, so we made sure it was on 'full power mode' and took off. Control was nuts - trying to keep to sane speeds for photography and flying hard into the wind then being blown back. Turning was a mission. I was done after not too long, just mentally cooked from flying. The heroes in this story are the tools which let us undertake such audacious ideas and know that we'll get something useable. Even in the worst conditions, we had a drone that could handle it (<a href="https://pixelfed.social/discover/tags/ANAFIUSA?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#ANAFIUSA</a>), software which made sense of scrappy data (<a href="https://pixelfed.social/discover/tags/OpenDroneMap?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#OpenDroneMap</a>) and tools to visualise it effectively alongside other data - which makes it all worthwhile (<a href="https://pixelfed.social/discover/tags/QGIS?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#QGIS</a>). There's another story about how we map on drifting ice, that's in the works. I was working on / funded by the Norwegian Nansen Legacy Project when this map was made, in mid-2021. My co-conspirators on this voyage were Polona Itkin and Tristan Petit. And this same drone lived to fly many more successful missions! <a href="https://pixelfed.social/discover/tags/Arctic?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Arctic</a> <a href="https://pixelfed.social/discover/tags/SeaIce?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#SeaIce</a> <a href="https://pixelfed.social/discover/tags/DroneMapping?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#DroneMapping</a> <a href="https://pixelfed.social/discover/tags/ResearchStories?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#ResearchStories</a> <a href="https://pixelfed.social/discover/tags/FOSS4G?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#FOSS4G</a>

Paul Knightly<a href="https://mstdn.social/tags/Photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#Photography</a> has been a natural complement to the <a href="https://mstdn.social/tags/fieldwork" class="mention hashtag" rel="nofollow noopener" target="_blank">#fieldwork</a> that I've performed over the years. It's afforded me opportunities to visit places like this canyon in northern <a href="https://mstdn.social/tags/Iceland" class="mention hashtag" rel="nofollow noopener" target="_blank">#Iceland</a>. The columnar basalt lining the canyon sidewalls are <a href="https://mstdn.social/tags/geologist" class="mention hashtag" rel="nofollow noopener" target="_blank">#geologist</a>'s dream! This view was captured from my <a href="https://mstdn.social/tags/drone" class="mention hashtag" rel="nofollow noopener" target="_blank">#drone</a> during a trip in 2019. I had just finished performing fieldwork focused on <a href="https://mstdn.social/tags/dronemapping" class="mention hashtag" rel="nofollow noopener" target="_blank">#dronemapping</a> several <a href="https://mstdn.social/tags/periglacial" class="mention hashtag" rel="nofollow noopener" target="_blank">#periglacial</a> and <a href="https://mstdn.social/tags/glacial" class="mention hashtag" rel="nofollow noopener" target="_blank">#glacial</a> sites across the island and took the last week of the trip for some sightseeing!
