Hey fellow nerds! Hope you're all enjoying the beginning of the week! I can’t believe it’s already June and officially summer! Between moving into a new place and doing deep edits on my thesis proposal, I’m working on
a new summer schedule now that I don’t have to TA or take classes. I’m using
the extra time to focus on research, and maybe a few fun things like shopping
and traveling.

Anyway,
I’m itching to talk about drones! I’ve been working with and flying drones a
lot this past semester as a way to learn a new skill for data acquisition for
my research. It turns out learning how to fly a drone is not as easy as it
looks…
 |
| The struggle is real! |
But
it’s been incredibly fun! You can fly drones for a number of reasons, whether
it’s professional or recreational, like fancy-looking videos, photos, and
surveys. For me, I’m learning that I can take large scale but detailed imagery
of my study sites so that I can create high-quality hydrologic models for my
research. To practice, I first performed a survey of a stretch of Revere Beach
north of Boston:

The
purpose of the survey was to make sure that drone surveys could actually serve
as an efficient alternative to manually conducted surveys for measuring beach
erosion. We flew four flights on a beautiful April morning and were able to
create this map:

It
was tricky, though. We were so close to the Boston Airport that the FAA
authorities asked us to fly below an altitude of 80 feet to make sure we didn’t
run the risk of hitting any planes. On top of that, piping plovers were nesting
nearby, so we had to make sure that our drone didn’t disturb the birds.
Luckily, we were not hit either a plane or a bird, and were able to come up
with a few comparisons of manual to drone surveys:

I’m
still doing some image processing to make the imagery a bit more accurate, and
when I get it, I’ll definitely post it! But, in the meantime, feel free to
contact me or comment below if you have any thoughts or questions!
