Forum:Request help/No more relation-data in the backup-files?

Forums → Request help or feedback → Request help/No more relation-data in the backup-files?

Hello all! Once in a while i download the latest backup (ogf-planet.osm.pbf) from this page https://data.opengeofiction.net/backups/ . With osmconvert i clip it to the area of my country of Neberly and i have some more scripts to get some data out of it. But with the files i downloaded in august and this morning i noticed there is no more data on relations in them. The files i had before (last from november 2021) did had relation-data. My question is then what happened? Is it on purpose that relation-data is no longer included? Is it somewhere else to find? Or is it some hick-up in te last months waiting to be repaired? Does someone know? Antoon (talk) 09:11, 1 October 2022 (UTC)

Are you sure your tools are up-to-date? I use the backup files all the time, and they have relation data in them. I just did a quick test on a fresh setup:

$ wget https://data.opengeofiction.net/backups/ogf-planet.osm.pbf
$ osmconvert ogf-planet.osm.pbf -o=gobras.osm.pbf -B=gobras.poly --complex-ways
# I can load this OSM.PBF file in JOSM, it has 2253 relations in it
$ osmconvert --version | head -2
osmconvert 0.8.10  Parameter Overview
$ osmconvert gobras.osm.pbf -o=gobras.o5m

          1     collection
          1     relation
          1     treaty

The tools used to create the backup changed around April 2022, older utils might not support reading the newer files? wangi (talk) 13:07, 1 October 2022 (UTC)

Thanks for your quick response Wangi. Then probably the change from april has resulted in it for me no longer able to get the relations out of the ogf-planet.osm.pbf file in the way i'm used too for many years. I downloaded the osmconvert.exe file, probably around 2015, and made a step by step plan to first clip the file to the Neberly-area resulting in a pbf-file and that converting to an osm-file. The osm.pbf-file and pbf-file i can't open to check on relations, but when opening the final osm-file i can see no more relations mentioned anymore.

I've tried before to find a new osmconvert-program but failed. The Windows-links on the Openstreetmap-site don't work or lead to a Russian site i don't trust. Wangi, you gave some syntaxes/codes but i have no idea on where or how to use such things. I would be grateful is someone could help me out, but then please keep it plain and simple.

I just ran a quite old version of osmconvert (installed around 2018 - the ogfsrtm server is intentionally out-of-date) with a brand-new ogf-planet.osm.pbf, using a gobras.poly - I got the same result as wangi (counts are different because I probably have a more expansive .poly file)

To add @Antoon: could you share the steps you take to get your extract? One thought - an incomplete xml (.osm.pbf) might "work" in osmconvert but be missing relations - those are at the end of the file, normally--Luciano (talk) 15:06, 2 October 2022 (UTC)
