Hello.I have checked at random a few mappings of project 11385 and
can't say anything else but that the validation went well wrong.
There are 2 people who validated most of them in iDeditor !!! and
without correcting any significant errors.
Info from "Overview of the ResultMaps @ neis-one.org"
Validator 1 (experience with mapping since early December 2021)
Quality assurance: iD editor: Resolved issues=679, Ignored warnings=1100
OSMI issues (details): routing=12, tagging=8
Osmosis issues: Level 1=0, Level 2=1, Level 3=2
Validator 2 experience with mapping since early December 2021)
Quality assurance: iD editor: Resolved issues=152, Ignored warnings=133
OSMI issues (details): routing=2
Osmosis issues: Level 1=0, Level 2=0, Level 3=0
Then I am not talking about whether or not poorly mapped buildings were
squared. Yes , changes were made, but most of them were not changed,
while in iDeditor the errors were reported.
To my opinion the best option here is to asign a few experenced
validators to this project, put all tasks back to "more validaton
needed" and start all over again with validating
Best regards.
