osmconvert - CSV and relations / ways

Question

Hello,

I have a question. Using osmconvert can reasonably be saved in CSV relations and ways?

With the nodes do not have a problem. Simply:

./osmconvert europe-latest.osm.pbf --out-csv --csv="@id @lat @lon"

The current record in the CSV relations and ways, however, does not make sense to me ...

It looks like this:

relation    3903876     
relation    3903985     
relation    3903986     
relation    3903987     
relation    3903988     
relation    3903989     
relation    3903990

How to identify what is in relation to what?

Ways and relations are too complex to be output in a CSV file. If you want to process ways and relations, other avenues might be more promising, e.g. writing a program that reads the OSM file (using e.g. the Osmium library), or loading the OSM file into a database with osm2pgsql and then running your analysis on the database.

If you really need a text file with one OSM object per line, try Osmium's "OPL" format.

How big will the MySQL database if the file osm.bz2 takes almost 900 MB?

The --csv="@id @lat @lon" in your question suggests that you need just IDs and coordinates. Maybe the option --all-to-nodes will help. It will retrieve the coordinates for all your ways and relations.
