# OSMPBF

https://github.com/openstreetmap/OSM-binary

Osmpbf is a Java/C++ library to read and write OpenStreetMap PBF files.
PBF (Protocol buffer Binary Format) is a binary file format for OpenStreetMap
data that uses Google Protocol Buffers as low-level storage.

For more information see https://wiki.openstreetmap.org/wiki/PBF_Format .

Note that this is a low-level library that does only part of the
encoding/decoding needed for actually writing/reading an OSM PBF file. For
something more complete see [libosmium](https://osmcode.org/libosmium/).

## Java Version

### Building with Maven

We publish the Java library to [Maven Central](https://mvnrepository.com/artifact/org.openstreetmap.pbf/osmpbf): ![Maven Central](https://img.shields.io/maven-central/v/org.openstreetmap.pbf/osmpbf.svg)

```xml
<dependency>
  <groupId>org.openstreetmap.pbf</groupId>
  <artifactId>osmpbf</artifactId>
  <version>${LATEST_VERSION}</version>
</dependency>
```

To build the Java library run:

```sh
mvn package
```

For a Java usage example, see
[`ReadFileTest`](https://github.com/openstreetmap/OSM-binary/blob/master/test.java/crosby/binary/ReadFileTest.java).

### Building with Ant

If you can not use Maven for some reason you can use the
[Ant](https://ant.apache.org/) instead:

```sh
ant
```

This will build `osmpbf.jar` in the main directory.

This build is also used for Debian packaging.

## C++ Version

To compile:

```sh
mkdir build && cd build
cmake ..
make
```

To install:

```sh
make install
```

There is a demo tool named osmpbf-outline that shows a debug output of some of
the contents of a PBF file. To run it:

```sh
demo/osmpbf-outline osm-file.osm.pbf
```

## Using the C++ Library

To include in your program use:

```c
#include <osmpbf/osmpbf.h>
```

and link with:

```
-pthread -lz -lprotobuf -losmpbf
```

## License

The .proto definition files and osmpbf.h are licensed under the MIT license.
The other source code is licensed under the LGPL v3+.
