GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

# 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/).
[![Github Actions C++ CI](https://github.com/openstreetmap/OSM-binary/actions/workflows/c.yml/badge.svg)](https://github.com/openstreetmap/OSM-binary/actions/workflows/c.yml)
[![Github Actions Java CI](https://github.com/openstreetmap/OSM-binary/actions/workflows/java.yml/badge.svg)](https://github.com/openstreetmap/OSM-binary/actions/workflows/java.yml)
[![Packaging status](https://repology.org/badge/tiny-repos/libosmpbf.svg)](https://repology.org/project/libosmpbf/versions)
## 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+.

.TH osmpbf-outline 1 LOCAL
.SH NAME
osmpbf-outline - outline the content of an .osm.pbf or .osh.pbf file
.SH SYNOPSIS
.B osmpbf-outline
[
.B --color
]
.I filename
.SH DESCRIPTION
.I osmpbf-outline
generates a colored outline of an .osm.pbf or .osh.pbf file, revealing its inner structure.
It does not decode all information nor does it check for of possible mistakes, but it will
warn on some bad mistakes one can make when generating .osm.pbf files.
This tool can be used by authors of .osm.pbf readers and writers and is useful to understand
the inner blob/block structure of .osm.pbf files.
Its source code is heavily documented and can be used as a good starting point
understanding on how to read and write .osm.pbf files with C++.
.SH OPTIONS
.TP 5
.B -c, --color
usually colorization is disabled when writing to a file descriptor that is not a tty (eg. when
the output is piped to a file or to a pager like more or less). Some pagers can handle ANSI
color code (
.I more
can, less can when invoked as
.I less -R
). To enforce colorization when working with such pagers, specify the
.B --color
flag.

/* OSM Binary file format
This is the master schema file of the OSM binary file format. This
file is designed to support limited random-access and future
extendability.
A binary OSM file consists of a sequence of FileBlocks (please see
fileformat.proto). The first fileblock contains a serialized instance
of HeaderBlock, followed by a sequence of PrimitiveBlock blocks that
contain the primitives.
Each primitiveblock is designed to be independently parsable. It
contains a string table storing all strings in that block (keys and
values in tags, roles in relations, usernames, etc.) as well as
metadata containing the precision of coordinates or timestamps in that
block.
A primitiveblock contains a sequence of primitive groups, each
containing primitives of the same type (nodes, densenodes, ways,
relations). Coordinates are stored in signed 64-bit integers. Lat&lon
are measured in units <granularity> nanodegrees. The default of
granularity of 100 nanodegrees corresponds to about 1cm on the ground,
and a full lat or lon fits into 32 bits.
Converting an integer to a latitude or longitude uses the formula:
$OUT = IN * granularity / 10**9$. Many encoding schemes use delta
coding when representing nodes and relations.

When a string is referenced, strings in the stringtable with indices:
0 : Is reserved (used as a delimiter in tags
A: 1 to 127 : Uses can be represented with 1 byte
B: 128 to 128**2-1 : Uses can be represented with 2 bytes,
C: 128*128 to X : Uses can be represented with 3 bytes in the unlikely case we have >16k strings in a block. No block will contain enough strings that we'll need 4 bytes.
There are goals that will improve compression:
1. I want to use 1 bytes for the most frequently occurring strings, then 2 bytes, then 3 bytes.
2. I want to use low integers as frequently as possible (for better
entropy encoding out of deflate)
3. I want the stringtable to compress as small as possible.
Condition 1 is obvious. Condition 2 makes deflate compress stringtable references more effectively.
When compressing entities, delta coding causes small positive integers to occur more frequently
than larger integers. Even though a stringtable references to indices of 1 and 127 both use one
byte in a decompressed file, the small integer bias causes deflate to use fewer bits to represent
the smaller index when compressed. Condition 3 is most effective when adjacent strings in the
stringtable have a lot of common substrings.
So, when I decide on the master stringtable to use, I put the 127 most frequently occurring
strings into A (accomplishing goal 1), and sort them by frequency (to accomplish goal 2), but
for B and C, which contain the less progressively less frequently encountered strings, I sort
them lexicographically, to maximize goal 3 and ignoring goal 2.
Goal 1 is the most important. Goal 2 helped enough to be worth it, and goal 3 was pretty minor,
but all should be re-benchmarked.

/* OSM Binary file format
This is the master schema file of the OSM binary file format. This
file is designed to support limited random-access and future
extendability.
A binary OSM file consists of a sequence of FileBlocks (please see
fileformat.proto). The first fileblock contains a serialized instance
of HeaderBlock, followed by a sequence of PrimitiveBlock blocks that
contain the primitives.
Each primitiveblock is designed to be independently parsable. It
contains a string table storing all strings in that block (keys and
values in tags, roles in relations, usernames, etc.) as well as
metadata containing the precision of coordinates or timestamps in that
block.
A primitiveblock contains a sequence of primitive groups, each
containing primitives of the same type (nodes, densenodes, ways,
relations). Coordinates are stored in signed 64-bit integers. Lat&lon
are measured in units <granularity> nanodegrees. The default of
granularity of 100 nanodegrees corresponds to about 1cm on the ground,
and a full lat or lon fits into 32 bits.
Converting an integer to a lattitude or longitude uses the formula:
$OUT = IN * granularity / 10**9$. Many encoding schemes use delta
coding when representing nodes and relations.
