<p>These pages describe how to install PROJ on your computer without compiling it
yourself. Below are guides for installing on Windows, Linux and Mac OS X. This
is a good place to get started if this is your first time using PROJ. More
advanced users may want to compile the software themselves.</p>

<p>PROJ is also available via cross platform package managers.</p>
<section id="conda">
<h4>Conda<a class="headerlink" href="#conda" title="Permalink to this headline">¶</a></h4>
<p>The conda package manager includes several PROJ packages. We recommend installing
from the <code class="docutils literal notranslate"><span class="pre">conda-forge</span></code> channel:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>conda install -c conda-forge proj
</pre></div>
</div>
<p>Using <code class="docutils literal notranslate"><span class="pre">conda</span></code> you can also install the PROJ data package. Here’s how to install
the <cite>proj-data</cite> package:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>conda install -c conda-forge proj-data
</pre></div>
</div>
<p>Available is also the legacy packages <code class="docutils literal notranslate"><span class="pre">proj-datumgrid-europe</span></code>,
<code class="docutils literal notranslate"><span class="pre">proj-datumgrid-north-america</span></code>, <code class="docutils literal notranslate"><span class="pre">proj-datumgrid-oceania</span></code> and

<h3>Windows<a class="headerlink" href="#windows" title="Permalink to this headline">¶</a></h3>
<p>The simplest way to install PROJ on Windows is to use the <a class="reference external" href="https://trac.osgeo.org/osgeo4w/">OSGeo4W</a> software
distribution. OSGeo4W provides easy access to many popular open source geospatial
software packages. After installation you can use PROJ from the OSGeo4W shell.
To install PROJ do the following:</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>If you have already installed software via OSGeo4W on your computer, or if
you have already installed QGIS on your computer, it is likely that PROJ is
already installed. Type “OSGeo4W Shell” in your start menu and check whether
that gives a match.</p>
</div>
<ol class="arabic simple">
<li><p>Download either the <a class="reference external" href="https://download.osgeo.org/osgeo4w/osgeo4w-setup-x86.exe">32 bit</a> or <a class="reference external" href="https://download.osgeo.org/osgeo4w/osgeo4w-setup-x86_64.exe">64 bit</a> installer.</p></li>
<li><p>Run the OSGeo4W setup program.</p></li>
<li><p>Select “Advanced Install” and press Next.</p></li>
<li><p>Select “Install from Internet” and press Next.</p></li>
<li><p>Select a installation directory. The default suggestion is fine in most cases. Press Next.</p></li>
<li><p>Select “Local package directory”. The default suggestion is fine in most cases. Press Next.</p></li>
<li><p>Select “Direct connection” and press Next.</p></li>
<li><p>Choose the download.osgeo.org server and press Next.</p></li>
<li><p>Find “proj” under “Commandline_Utilities” and click the package in the “New” column until the version you want to install appears.</p></li>
<li><p>Press next to install PROJ.</p></li>
</ol>
<p>You should now have a “OSGeo” menu in your start menu. Within that menu you can
find the “OSGeo4W Shell” where you have access to all the OSGeo4W applications,
including proj.</p>

<p>How to install PROJ on Linux depends on which distribution you are using. Below

<p>The following guides show how to compile and install the software using CMake.</p>

<section id="build-steps">
<h3>Build steps<a class="headerlink" href="#build-steps" title="Permalink to this headline">¶</a></h3>
<p>With the CMake build system you can compile and install PROJ on more or less any
platform. After unpacking the source distribution archive step into the source-
tree:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>cd proj-9.0.0
</pre></div>
</div>
<p>Create a build directory and step into it:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>mkdir build
cd build
</pre></div>
</div>
<p>From the build directory you can now configure CMake, build and install the binaries:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>cmake ..
cmake --build .
cmake --build . --target install
</pre></div>
</div>
<p>On Windows, one may need to specify generator:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>cmake -G "Visual Studio 15 2017" ..
</pre></div>
</div>
<p>If the SQLite3 dependency is installed in a custom location, specify the
paths to the include directory and the library:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>cmake -DSQLITE3_INCLUDE_DIR=/opt/SQLite/include -DSQLITE3_LIBRARY=/opt/SQLite/lib/libsqlite3.so ..
</pre></div>
</div>
<p>Alternatively, the custom prefix for SQLite3 can be specified:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>cmake -DCMAKE_PREFIX_PATH=/opt/SQLite ..
</pre></div>
</div>
<p>Tests are run with:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>ctest
</pre></div>
</div>
<p>With a successful install of PROJ we can now install data files using the
<strong class="program">projsync</strong> utility:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>projsync --system-directory
</pre></div>
</div>
<p>which will download all resource files currently available for PROJ. If less than
the entire collection of resource files is needed the call to <strong class="program">projsync</strong>
can be modified to suit the users needs. See <a class="reference internal" href="apps/projsync.html#projsync"><span class="std std-ref">projsync</span></a> for more options.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>The use of <strong class="program">projsync</strong> requires that network support is enabled (the
default option). If the resource files are not installed using
<strong class="program">projsync</strong> PROJ will attempt to fetch them automatically when a
transformation needs a specific data file. This requires that

<p>As an alternative on systems where network access is disabled, the
<a class="reference internal" href="resource_files.html#datumgrid"><span class="std std-ref">proj-data</span></a>
package can be downloaded and added to the <span class="target" id="index-1"></span><a class="reference internal" href="usage/environmentvars.html#envvar-PROJ_LIB"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">PROJ_LIB</span></code></a> directory.</p>
