Update: Telenav publishes weekly planet Parquet files at osm-data.skobbler.net
The project intends to provide a way to get the OpenStreetMap data available in a Big Data friendly format as Parquet.
Currently any PBF file is converted into three parquet files, one for each type of entity from the original PBF (Nodes, Ways and Relations).
In order to get started:
git clone https://github.com/adrianulbona/osm-parquetizer.git
cd osm-parquetizer
mvn clean package
java -jar target/osm-parquetizer-1.0.1-SNAPSHOT.jar path_to_your.pbfFor example, by running:
java -jar target/osm-parquetizer-1.0.1-SNAPSHOT.jar romania-latest.osm.pbfIn a few seconds (on a decent laptop) you should get the following files:
-rw-r--r-- 1 adrianbona adrianbona 145M Apr 3 19:57 romania-latest.osm.pbf
-rw-r--r-- 1 adrianbona adrianbona 372M Apr 3 19:58 romania-latest.osm.pbf.node.parquet
-rw-r--r-- 1 adrianbona adrianbona 1.1M Apr 3 19:58 romania-latest.osm.pbf.relation.parquet
-rw-r--r-- 1 adrianbona adrianbona 123M Apr 3 19:58 romania-latest.osm.pbf.way.parquetThe parquet files have the following schemas:
