So it can be simply told them that we use only unprocessed tracks and
if possible they shall do the same. If they do not have it we can't
use them.
Generally I suggest to tell them what we would like to get and we do
not really need so they can respond.

>(xlation) I looked, for example, at BP III. district modified something, source = maxar was premium. The problem with this is that we have previously clarified that area from an orthophoto. So if they modify geometry based on "best imagery", they might just make a mistake.

This could be phrased as: we have several local orthophotos which has
much higher precision and resolution as Maxar, so generally you should
not correct anything based on satellite imagery unless you have
verified that there is no data source with better accuracy. Generally
you are strongly advised against "fixing" anything by satellite
imagery.

This racist commentary could have been phrased as:
Hungarian road classification system is not exactly the same as
elsewhere (they are a little different in every country), so we would
kindly ask you to familiarise yourself with the system before you plan
to start making larger changes. The wikipages (in Hungarian) detail
the system but there are still cases where the best source of
information is checking how it's done in other parts of the country.

>(xlation) This is the most problematic because it is not detailed on what basis they are validated and what errors are planned (automatically?) To be corrected.

That is a question to be asked.
What kind of validation do you mean and on what basis do you plan to
fix anything?

I see it as a request for help.
