QuackOSM

An open-source tool for reading OpenStreetMap PBF files using DuckDB.

What is QuackOSM 🦆?

Scalable reader for OpenStreetMap ProtoBuffer (pbf) files.
Is based on top of DuckDB[^1] with its Spatial[^2] extension.
Saves files in the GeoParquet[^3] file format for easier integration with modern cloud stacks.
Utilizes multithreading unlike GDAL that works in a single thread only.
Can filter data based on geometry without the need for ogr2ogr clipping before operation.
Can filter data based on OSM tags.
Utilizes caching to reduce repeatable computations.
Can be used as Python module as well as a beautiful CLI based on Typer[^4].

Installing

As pure Python module

pip install quackosm

With beautiful CLI

pip install quackosm[cli]

Usage

If you already have downloaded the PBF file 📁🗺️

Load data as a GeoDataFrame

>>> import quackosm as qosm
>>> qosm.convert_pbf_to_geodataframe(monaco_pbf_path)

How does it work?

Basic logic

QuackOSM utilizes ST_ReadOSM function from DuckDB's Spatial extension to read raw data from the PBF file:

Nodes with coordinates and tags;
Ways with nodes refs and tags;
Relations with nodes and ways refs, ref roles and tags.

Library contains a logic to construct geometries (points, linestrings, polygons) from those raw features.

Read nodes from the PBF file, save them to the parquet file.
1. (Optional) Filter nodes based on geometry filter
2. (Optional) Filter nodes based on tags filter
Read ways from the PBF file, save them to the parquet file.
1. Select all nodes refs and join them with previously read nodes.
2. (Optional) Filter ways based on geometry filter - join intersecting nodes
3. (Optional) Filter ways based on tags filter
Read relations from the PBF file, save them to the parquet file.

Geometry validation

You might ask a question: How do I know that these geometries are reconstructed correctly?

To answer this question, the QuackOSM has implemented dedicated tests that validate the results of GDAL geometries vs QuackOSM. This might come as a surprise, but since OSM geometries aren't always perfectly defined (especially relations), the QuackOSM can even fix geometries that are loaded with weird artifacts by GDAL.

You can inspect the comparison algorithm in the test_gdal_parity function from tests/base/test_pbf_file_reader.py file.

Caching

Library utilizes caching system to reduce repeatable computations.

By default, the library is saving results in the files directory created in the working directory. Result file name is generated based on the original *.osm.pbf file name.

Original file name to be converted: example.osm.pbf.

Default output without any filtering: example_nofilter_noclip_compact.parquet.

The nofilter part can be replaced by the hash of OSM tags provided for filtering. example_a9dd1c3c2e3d6a94354464e9a1a536ef44cca77eebbd882f48ca52799eb4ca91_noclip_exploded.parquet

The noclip part can be replaced by the hash of geometry used for filtering. example_nofilter_430020b6b1ba7bef8ea919b2fb4472dab2972c70a2abae253760a56c29f449c4_compact.parquet

The compact part can also take the form of exploded, it represents the form of OSM tags - either kept together in a single dictionary or split into columns.

When filtering by selecting individual features IDs, an additional hash based on those IDs is appended to the file. example_nofilter_noclip_compact_c740a1597e53ae8c5e98c5119eaa1893ddc177161afe8642addcbe54a6dc089d.parquet

When the keep_all_tags parameter is passed while filtering by OSM tags, and additional alltags component is added after the osm filter hash part. example_a9dd1c3c2e3d6a94354464e9a1a536ef44cca77eebbd882f48ca52799eb4ca91_alltags_noclip_compact.parquet

General schema of multiple segments that are concatenated together: pbf_file_name_(osm_filter_tags_hash_part/nofilter)(_alltags)_(clipping_geometry_hash_part/noclip)_(compact/exploded)(_filter_osm_ids_hash_part).parquet

If the WKT mode is turned on, then the result file will be saved with a _wkt suffix.

Memory usage

DuckDB queries requiring JOIN, GROUP and ORDER BY operations are very memory intensive. Because of that, some steps are divided into chunks (groups) with a set number of rows per chunk.

QuackOSM has been roughly tuned to different workloads. The rows_per_group variable is set based on an available memory in the system:

Memory	Rows per group
< 8 GB	100 000
8 - 16 GB	500 000
16 - 24 GB	1 000 000
> 24 GB	5 000 000

WSL usage: sometimes code can break since DuckDB is trying to use all available memory, that can be occupied by Windows.

Resources usage

The algorithm depends on saving intermediate .parquet files between queries. As a rule of thumb, when parsing a full file without filtering, you should have at least 10x more free space on disk than the base file size (100MB pbf file -> 1GB free space to parse it).

Below you can see the chart of resources usage during operation. Generated on a Github Actions Ubuntu virtual machine with 4 threads and 16 GB of memory.
