<div>Before I plan to upload the boundaries import data for
Surabaya, I have received some feedback and helped by <a
moz-do-not-send="true"
href="https://wiki.openstreetmap.org/wiki/User:Capiscuas">Ivan
Garcia</a> who has expertise in correcting boundaries and
has previously worked with us in settling Jakarta
boundaries.</div>

yes, but is no anwers about your experence. The script of Ivan
looks fine and i'll check it with real data - of course without
uploading.<br>

<div>The current raw file has the boundary relations already,
which I think is quite accurate. I will send the link to the
raw gis data when it's uploaded on github.</div>

It's not a question of <b>data quality</b>, it's a question about
the <b>technical way</b> adding boundary relations as
multipolygons to osm - without damaging the "neighbourhood" and
without deleting the old releations with their history before.
Ivan's script seems to do the job in an empty area but does not
respect the outer borders ("neighbourhood") and the history.<br>
<br>
We had a lot of problems during such a task in Mexico Nov. '15
till March '16 . See <a moz-do-not-send="true"

They even damaged the international boundaries of the USA,
Guatemala and Belize. We had to stop them and they had to change a
lot in their working process. <b>Now</b> they know how to do
this. ;)<br>

<div>In regards to the current boundaries in Surabaya, we had
contacted those who mapped them previously but they were
unable to provide the data license / approval and I believe
our data which is formally attained from Indonesian
government is more accurate. <br>

This was only an example of what did go wrong and may go wrong
again. At least at the edges of the import area.<br>

<div>I might need to clarify that HOT Indonesia, which is
where I work now, has not focused its work yet on the issue
of data import due to some problem attaining the data from
Indonesian government and in explaining about the
sensitivity of it to Indonesian OpenStreetMap Community.
Thank you very much for your input, we plan to work more on
correcting this issue following OpenStreetMap procedures of
validating existing data and improving data quality in the
incoming project.</div>

btw: Working with HOT - not OSM? Talking of OpenStreetMap
Community as an extra organisation? Strange to me. You are member
of the OSM Community too. But that is another "problem".<br>
