Hi Serkan,
I am in the process of extending Mapswipe (http://www.missingmaps.org/)
an app that is used to create some of the task manager task geometries.
Together with Benni Herfort at Heidelberg university, we're setting up a
workflow to help people validate building footprints produced by ML
Hi Michael,
I see, thank you. We'll make sure we handle those cases correctly then.
Thank you very much for pointing that out.
Best,
Serkan

Hi Serkan,
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.

Thanks a lot, the geojson file seems to be more than enough for us really:)
Thanks you for your help, really appreciate it.

Hi Serkan,
Glad I could be helpful :)
5 Coordinates because the feature is a polygon and the final coordinate
duplicates the first - closing the polygon.
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
Serkan,
The last value is the same as the first, it closes the polygon.

Hi Joseph,
Thanks a lot, this was exactly what we needed indeed! Much appreciated,
thank you for your help.
Is there a reason that there are five coordinates for the tile btw, instead
of four?

Thanks a lot for the discussions and your time. I will definitely try some
quality control methods as you suggested. Sometimes more data also increase
the accuracy even when it's noisy, that part is not an exact science
unfortunately:) But I will try using only %100 validated tasks as you
Hi Serkan,
I've not looked into this properly, but a quick look at a project on the
Task Manager shows I can find a validated square:
https://tasks.hotosm.org/project/5182?task=2212#bottom
This task 2212 appears in the project geojson, and marked as validated:
As John is saying, quality can vary a lot. You should look at the thread where

I've done a lot of validation in HOT. Some is done by people with
little experience so I don't think validated tiles would be much use to
you. Also be aware that some imagery can be three years out of date so
the imagery can vary. The sort of problems you'll run into are much of

Dear John,
the question isn't about imports. Seems guys are preparing dataset to train
and test models and they need to download data that's been already
validated within Missing Maps, as a "ground truth".
Is there a way to get the precise coordinates of the areas where this job
is done or
Essentially you are proposing an import. There are OpenStreetMap rules
about how this should be done. It can be done, Microsoft has released
building outlines for the US which were created in this manner but the
import itself is being done in sections by conventional mappers.
You will need the
Hi,
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
