[Talk-ke] Dadaab refugee camp data OSM import review

[Mugeha Laura]

Hi Naomi,


Thank you so much for working on importing essential data to OSM and, in
particular missing infrastructure facilities in Dadaab. On behalf of a
group of OSM Kenya members who reviewed the planned import, here are some
thoughts / questions / comments that we have:


   -

   *Data quality and accuracy*

The linked maps are dated January  2019; a lot of changes occur daily
across refugee camps; therefore, one year+ is quite long for this dataset
to reflect the actual state on the ground. Has the data been updated since
the initial data collection? Are all these facilities operational? If so,
can this be noted as well?


   -

   *Closed camps*

As recently noticed while mapping project 8823
<https://tasks.hotosm.org/projects/8823> to support COVID-19 response
efforts in Dadaab, several camps have been closed between 2018-2019. See
media reports here
<https://reliefweb.int/report/kenya/unhcr-operational-update-dadaab-kenya-june-2019#:~:text=Kambioos%20refugee%20camp%20was%20closed,support%20in%20Kenya%20and%20Somalia.>.
As part of your data preparation and cleaning process, have these areas
been catered for, i.e., removing features in these areas so that we do not
import non-operational infrastructure?


   -

   *OSM Tagging*

Kindly take note of specific tagging guidelines for the East African region
here <https://wiki.openstreetmap.org/wiki/East_Africa_Tagging_Guidelines>
(water point infrastructure) and, similarly, guidelines used by Map Kibera
here <https://www.mapkibera.org/wiki/index.php?title=Tagging>(health
facilities and water point infrastructure).


   -

   *Import schedule*

Could you kindly give more information on this: Data prep, data merging,
conflict resolution process, QA, etc. This will be important for future
updates and imports.


   -

   *Corrections and updates*

Are there plans to update and maintain this data? If so, could you add a
comment on the same?


   -

   *Deletion*

For validation and future updates, kindly note that deleting something for
a project might affect someone else’s  - it’s difficult to know the true
“provenance” of an object, and we all want to make an accurate map.
Secondly is the practicalities of databases: deleted nodes still take up
room in the database, and for an open-source platform that is not
well-funded, it is vital to conserve database space. Its therefore
advisable to move nodes, and add attributes to enrich existing data as
opposed to deletion.

Thank you so much for reaching out to the local OSM community in Kenya via
the mailing list and Twitter <https://twitter.com/OSMKenya> :) You can also
get more feedback from the global OSM community by sharing this on the
imports mailing list: https://lists.openstreetmap.org/listinfo/imports
