Topics File format OSM import tools Programming with OSM data
(.osm, .pbf )

File format .osm, .osc (XML file) All nodes contain the
location in the WGS84 reference system. Simplest format and readable for human. .osc is OSM Change file. .pbf (Protocol Bu ff er) Binary format and half of the size of gzipped osm file. .proto file defines format and many programming language supports Protocol Bu ff er. Some columns are delta‑encoded. .o5m, .o5c Design for small file size and fast processing. .osh History file includes all changes.

Compare Human reaable Process speed ﬁle size osm yes too
slow biggest pbf no fast small o5m no fast small pbf is smaller than o5m but 7zip compressed o5m is smaller than pbf.

osmconvert osmconvert use to convert and process OpenStreetMap ﬁle. Supports
.osm, .osc, .osh, .o5m, .o5c and .pbf ﬁles.

osm import tools osm2pgsql imposm3 ogr2ogr osm2pgrouting

osm2pgsql Most famous tool to import osm data to postgresql.
Written in C++ and libosmium. OpenStreetMap.org default style depends osm2pgsql. https://github.com/gravitystorm/openstreetmap‑ carto/blob/master/openstreetmap‑carto.style Control import tags with style ﬁle.

Imposm 3 Alternative osm import tool. Imposm 3 is written
in Go. Imposm 2 is written in Python and configurations/mappings are not compatible. High performance and firster than osm2pgsql. Create table structrue with YAML/JSON file. We can design postgresql table structure for rendering server.

Notice: Imposm 3 Current master can't import japan pbf. Use
osm2vectortiles/imposm3 instead of master branch. $ g i t c l o n e h t t p s : / / g i t h u b . c o m / o s m 2 v e c t o r t i l e s / i m p o s m 3 \ $ G O P A T H / s r c / g i t h u b . c o m / o m n i s c a l e / i m p o s m 3 $ c d $ G O P A T H / s r c / g i t h u b . c o m / o m n i s c a l e / i m p o s m 3 $ g i t r e s e t ‐ ‐ h a r d 0 6 0 f 4 1 1 1 f c a f 4 5 9 e 8 b 0 9 a 0 3 5 1 8 3 6 d f e 8 e b 4 d c 9 4 3 $ g o g e t $ g o i n s t a l l

osm2pgsql vs Imposm 3: table structures osm2pgsql controls tags with
style file but it can't control table structures. Imposm 3 controls table structures and tags in json or yaml file (mapping file).

Programming for OSM ﬁles.

Libraries for programmer osmium (C++, Python, Node.js) libosmpbfreader (C++) osmpbfreader‑rs
(Rust) rust‑osm‑reader (Rust)

osmium C++ library for osm data. http://osmcode.org/libosmium/ It provide C++11
header library. Easy to contain your C++ product with cmake. osmium provide python binding (PyOsmium) and node.js binding (Node‑Osmium). Supports too many OpenStreetMap ﬁle format. Old versions are still used in many products. https://github.com/joto/osmium If you ﬁnd the product use old version, it's pull‑request chance (or death road).

concept osmium provide simple interfaces. open many format (.osm, .osh,
.osc, .pbf, ...) OSM Entity classes (Node, Way, Relation, Changesets, ...) Also provide iterator for tag. Basic Types (OSM id, version, user, Location, Segment(connection between two location), Box) process each OSM Entities in Handler

libosmpbfreader and osmpbfreader‑rs libosmpbfreader is C++ library to read osm's
pbf ﬁle. https://github.com/CanalTP/libosmpbfreader This library supports only osm id, location and tags. Can't make user stats. osmpbfreader‑rs is Rust library and same concept as libosmpbfreader. https://github.com/TeXitoi/osmpbfreader‑rs It's use iterator and match.

rust‑osm‑reader (pbf‑reader) rust‑osm‑reader is Rust implementation and uses multithreaded approach
for reading data. https://gitlab.com/oleksandromelchuk/rust‑osm‑reader This library also supports only osm id, location and tags. But I hacked to get user name. use Concurrency and match Package name has problem, pbf is not used only OpenStreeetMap.

benchmark result Program Taiwan Japan osmium (C++) 0.58 12.33 rust‑osm‑reader
master (Rust) 1.00 16.40 rust‑osm‑reader 0.1.2 (Rust) 2.20 61.08 libosmpbfreader (C++) 3.74 76.39 osmpbfreader‑rs (Rust) 4.13 88.85 pyosmium (Python) 4.13 89.93 node‑osmium (Node) 8.72 none

summary osmium has good interface and better speed. If you
are C++11/Python programmer, osmium is best solution in now. If you are Javascript programmer, let's hack node‑osmium. Rust is hot programming language in OSM. Let's try Rust.
