I asked this question on the github of the 3Dbag:
''I saw that the “identificatie”: number from the 3DBAG dataset is different from the “identificatie”: number of the BAG dataset from Pdok.
It seems like the 3DBAG “identificatie” number always adds a 0 at the start of the number, am I correct?’’
I got a reply from the 3Dbag team:
"That’s correct. In this case pdok is incorrect, because apparently they cast the identificatie to integers, which removes the 0-padding.
Why have a 0-padded ID? Because the first 4 digits of the ID is the municipality code, which begins below 1000.
For the correct identificatie attribute please refer to the official BAG viewer: https://bagviewer.kadaster.nl"
My question is, is it possible to know which dataset source has the right identificatie number? PDOK or bagviewer.kadaster.nl? And is it possible to have the identificatie data not being changed from one data source to the other?
