just to let you know: Task squares do not have to be squares, they
can have arbitrary polygon boundaries. You will find examples for
these in nearly every project. <br>

<div>5 Coordinates because the feature is a polygon and
the final coordinate duplicates the first - closing the

</div>
<div>It might be worth looking at the Task Manager github
page to see if there's any plans to present coordinates
via the API. I had a very quick look at the
documentation and couldn't find anything. Calling the
API for the above gives me as follows:</div>

I don't know if that would be more useful to you if it
contained those coordinates.

<div dir="ltr">Hi,
<div>I am a graduate student in a Data Science
program, and I wanted to get in touch with
you because me and my two other friends are
interested in working on a machine learning
project to map areas using their satellite
images and produce their labels. If we
obtain a high accuracy, we thought it could
be of use to the hotosm and the missingmaps
initiatives.<br>
</div>
<div>
<div><br>
</div>
<div>I have first heard about Missing Maps
when I came across a mapathlon event two
years ago in Istanbul. We were in search
for a class project for one of our courses
and I remembered about the mapathlon event
and we would be very happy if we could
contribute to the this wonderful
initiative. There are already some
previous successful works on this subject,
so we are very hopeful that we could come
up with an algorithm with high accuracy.</div>
<div><br>
</div>
<div>In order to develop the model, we need
to extract bounding boxes of the validated
tiles we see at hotosm. Then we will
extract the satellite images and their
labels using the label-maker API which is
developed by DevSeed. Is there a method to
extract the coordinates of these validated
tiles? </div>
<div><br>
</div>
<div>Thank you for your time and help.</div>
