osm2pgsql

https://osm2pgsql.org

osm2pgsql is a tool for loading OpenStreetMap data into a PostgreSQL / PostGIS database suitable for applications like rendering into a map, geocoding with Nominatim, or general analysis.

See the documentation for instructions on how to install and run osm2pgsql.

Features

  • Converts OSM files to a PostgreSQL DB
  • Conversion of tags to columns is configurable in the style file
  • Able to read .gz, .bz2, .pbf and .o5m files directly
  • Can apply diffs to keep the database up to date
  • Support the choice of output projection
  • Configurable table names
  • Gazetteer back-end for Nominatim
  • Support for hstore field type to store the complete set of tags in one database field if desired

Installing

Most Linux distributions include osm2pgsql. It is available on macOS with Homebrew and Windows builds are also available. See https://osm2pgsql.org/doc/install.html for details.

Building

The latest source code is available in the osm2pgsql git repository on GitHub and can be downloaded as follows:

git clone git://github.com/openstreetmap/osm2pgsql.git

Osm2pgsql uses the cross-platform CMake build system to configure and build itself.

Required libraries are

It also requires access to a database server running PostgreSQL 9.5+ and PostGIS 2.2+.

Make sure you have installed the development packages for the libraries mentioned in the requirements section and a C++ compiler which supports C++14.

To rebuild the included man page you'll need the pandoc tool.

First install the dependencies.

On a Debian or Ubuntu system, this can be done with:

sudo apt-get install make cmake g++ libboost-dev libboost-system-dev \
  libboost-filesystem-dev libexpat1-dev zlib1g-dev \
  libbz2-dev libpq-dev libproj-dev lua5.3 liblua5.3-dev pandoc

On a Fedora system, use

sudo dnf install cmake make gcc-c++ boost-devel expat-devel zlib-devel \
  bzip2-devel postgresql-devel proj-devel proj-epsg lua-devel pandoc

On RedHat / CentOS first run sudo yum install epel-release then install dependencies with:

sudo yum install cmake make gcc-c++ boost-devel expat-devel zlib-devel \
  bzip2-devel postgresql-devel proj-devel proj-epsg lua-devel pandoc

On a FreeBSD system, use

pkg install devel/cmake devel/boost-libs textproc/expat2 \
  databases/postgresql94-client graphics/proj lang/lua52

On Alpine, use

apk --update-cache add cmake make g++ boost-dev expat-dev \
  bzip2-dev zlib-dev libpq proj-dev lua5.3-dev postgresql-dev

Once dependencies are installed, use CMake to build the Makefiles in a separate folder:

mkdir build && cd build
cmake ..

If some installed dependencies are not found by CMake, more options may need to be set. Typically, setting CMAKE_PREFIX_PATH to a list of appropriate paths is sufficient.

When the Makefiles have been successfully built, compile with

make

The man page can be rebuilt with:

make man

The compiled files can be installed with

sudo make install

By default, the Release build with debug info is created and no tests are compiled. You can change that behavior by using additional options like following:

cmake .. -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTS=ON

Using the PROJ library

Osm2pgsql has builtin support for the Latlong (WGS84, EPSG:4326) and the WebMercator (EPSG:3857) projection. If you need other projections you have to compile with the PROJ library.

Both the older API (PROJ version 4) and the newer API (PROJ version 6.1 and above) are supported. Usually the CMake configuration will find a suitable version and use it automatically, but you can set the USE_PROJ_LIB CMake cache variable to choose between the following behaviours:

  • 4: Look for PROJ library with API version 4. If it is not found, stop with error.
  • 6: Look for PROJ library with API version 6. If it is not found, stop with error.
  • off: Build without PROJ library.
  • auto: Choose API 4 if available, otherwise API 6. If both are not available build without PROJ library. (This is the default.)

Using LuaJIT

To speed up Lua tag transformations, LuaJIT can be optionally enabled on supported platforms. This can speed up processing considerably.

On a Debian or Ubuntu system install the LuaJIT library:

sudo apt-get install libluajit-5.1-dev

Configuration parameter WITH_LUAJIT=ON needs to be added to enable LuaJIT. Otherwise make and installation steps are identical to the description above.

cmake -D WITH_LUAJIT=ON ..

Use osm2pgsql --version to verify that the build includes LuaJIT support. The output should show something like

Lua 5.1.4 (LuaJIT 2.1.0-beta3)
