<p><a class="reference external" href="https://www.gaia-gis.it/fossil/libspatialite">SpatiaLite</a> adds spatial support to SQLite, turning it into a full-featured
spatial database.</p>
<p>Check first if you can install Spatialite from system packages or binaries. For
example, on Debian-based distributions, try to install the <tt class="docutils literal"><span class="pre">spatialite-bin</span></tt>
package. For Mac OS X, follow the
<a class="reference internal" href="#spatialite-macosx"><em>specific instructions below</em></a>. For Windows, you may
find binaries on <a class="reference external" href="http://www.gaia-gis.it/gaia-sins/">Gaia-SINS</a> home page. In any case, you should always
be able to <a class="reference internal" href="#spatialite-source"><em>install from source</em></a>.</p>
<p>When you are done with the installation process, skip to <a class="reference internal" href="#create-spatialite-db"><em>Creating a spatial database for SpatiaLite</em></a>.</p>

<p><a class="reference internal" href="geolibs.html#geospatial-libs"><em>GEOS and PROJ.4</em></a> should be installed prior to building
SpatiaLite.</p>
<div class="section" id="s-sqlite">
<span id="sqlite"></span><h3>SQLite<a class="headerlink" href="#sqlite" title="Permalink to this headline">¶</a></h3>
<p>Check first if SQLite is compiled with the <a class="reference external" href="http://www.sqlite.org/rtree.html">R*Tree module</a>. Run the sqlite3
command line interface and enter the following query:</p>
<div class="highlight-python"><pre>sqlite> CREATE VIRTUAL TABLE testrtree USING rtree(id,minX,maxX,minY,maxY);</pre>
</div>
<p>If you obtain an error, you will have to recompile SQLite from source. Otherwise,
just skip this section.</p>
<p>To install from sources, download the latest amalgamation source archive from
the <a class="reference external" href="http://www.sqlite.org/download.html">SQLite download page</a>, and extract:</p>
<div class="highlight-python"><pre>$ wget http://sqlite.org/sqlite-amalgamation-3.6.23.1.tar.gz
$ tar xzf sqlite-amalgamation-3.6.23.1.tar.gz
$ cd sqlite-3.6.23.1</pre>
</div>
<p>Next, run the <tt class="docutils literal"><span class="pre">configure</span></tt> script – however the <tt class="docutils literal"><span class="pre">CFLAGS</span></tt> environment variable
needs to be customized so that SQLite knows to build the R*Tree module:</p>
<div class="highlight-python"><pre>$ CFLAGS="-DSQLITE_ENABLE_RTREE=1" ./configure
$ make
$ sudo make install
$ cd ..</pre>
</div>

<p>Get the latest SpatiaLite library source and tools bundle from the

</div>
<p>Prior to attempting to build, please read the important notes below to see if
customization of the <tt class="docutils literal"><span class="pre">configure</span></tt> command is necessary. If not, then run the
<tt class="docutils literal"><span class="pre">configure</span></tt> script, make, and install for the SpatiaLite library:</p>
<div class="highlight-python"><pre>$ cd libspatialite-amalgamation-2.3.1
$ ./configure # May need to be modified, see notes below.
$ make
$ sudo make install
$ cd ..</pre>
</div>
<p id="spatialite-tools">Finally, do the same for the SpatiaLite tools:</p>
<div class="highlight-python"><pre>$ cd spatialite-tools-2.3.1
$ ./configure # May need to be modified, see notes below.
$ make
$ sudo make install
$ cd ..</pre>
</div>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p>If you’ve installed GEOS and PROJ.4 from binary packages, you will have to specify
their paths when running the <tt class="docutils literal"><span class="pre">configure</span></tt> scripts for <em>both</em> the library and the
tools (the configure scripts look, by default, in <tt class="docutils literal"><span class="pre">/usr/local</span></tt>). For example,
on Debian/Ubuntu distributions that have GEOS and PROJ.4 packages, the command would be:</p>
<div class="last highlight-python"><pre>$ ./configure --with-proj-include=/usr/include --with-proj-lib=/usr/lib --with-geos-include=/usr/include --with-geos-lib=/usr/lib</pre>
</div>

<div class="admonition note">
<p class="first admonition-title">Note</p>
<p>For Mac OS X users building from source, the SpatiaLite library <em>and</em> tools
need to have their <tt class="docutils literal"><span class="pre">target</span></tt> configured:</p>
<div class="last highlight-python"><pre>$ ./configure --target=macosx</pre>

<p>If you are on Python 2.6, you will also have to compile pysqlite2, because
<tt class="docutils literal"><span class="pre">SpatiaLite</span></tt> must be loaded as an external extension, and the required
<tt class="docutils literal"><span class="pre">enable_load_extension</span></tt> method is only available in versions 2.5+ of
pysqlite2. Thus, download pysqlite2 2.6, and untar:</p>
<div class="highlight-python"><pre>$ wget http://pysqlite.googlecode.com/files/pysqlite-2.6.3.tar.gz
$ tar xzf pysqlite-2.6.3.tar.gz
$ cd pysqlite-2.6.3</pre>
</div>
<p>Next, use a text editor (e.g., <tt class="docutils literal"><span class="pre">emacs</span></tt> or <tt class="docutils literal"><span class="pre">vi</span></tt>) to edit the <tt class="docutils literal"><span class="pre">setup.cfg</span></tt> file

<div class="admonition note">

<p>After modifying <tt class="docutils literal"><span class="pre">setup.cfg</span></tt> appropriately, then run the <tt class="docutils literal"><span class="pre">setup.py</span></tt> script

<p>Mac OS X users should follow the instructions in the <a class="reference internal" href="index.html#kyngchaos"><em>KyngChaos packages</em></a> section,
as it is much easier than building from source.</p>
<p>When <a class="reference internal" href="#create-spatialite-db"><em>Creating a spatial database for SpatiaLite</em></a>, the <tt class="docutils literal"><span class="pre">spatialite</span></tt> program is required.
However, instead of attempting to compile the SpatiaLite tools from source,
download the <a class="reference external" href="http://www.gaia-gis.it/spatialite-2.3.1/binaries.html">SpatiaLite Binaries</a> for OS X, and install <tt class="docutils literal"><span class="pre">spatialite</span></tt> in a
location available in your <tt class="docutils literal"><span class="pre">PATH</span></tt>. For example:</p>
<div class="highlight-python"><pre>$ curl -O http://www.gaia-gis.it/spatialite/spatialite-tools-osx-x86-2.3.1.tar.gz
$ tar xzf spatialite-tools-osx-x86-2.3.1.tar.gz
$ cd spatialite-tools-osx-x86-2.3.1/bin
$ sudo cp spatialite /Library/Frameworks/SQLite3.framework/Programs</pre>
</div>
<p>Finally, for GeoDjango to be able to find the KyngChaos SpatiaLite library,
add the following to your <tt class="docutils literal"><span class="pre">settings.py</span></tt>:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="n">SPATIALITE_LIBRARY_PATH</span><span class="o">=</span><span class="s">'/Library/Frameworks/SQLite3.framework/SQLite3'</span>

<div class="section" id="s-creating-a-spatial-database-for-spatialite">

<p>After you’ve installed SpatiaLite, you’ll need to create a number of spatial
metadata tables in your database in order to perform spatial queries.</p>
<p>If you’re using SpatiaLite 2.4 or newer, use the <tt class="docutils literal"><span class="pre">spatialite</span></tt> utility to
call the <tt class="docutils literal"><span class="pre">InitSpatialMetaData()</span></tt> function, like this:</p>
<div class="highlight-python"><pre>$ spatialite geodjango.db "SELECT InitSpatialMetaData();"
the SPATIAL_REF_SYS table already contains some row(s)
InitSpatiaMetaData ()error:"table spatial_ref_sys already exists"
0</pre>
</div>
<p>You can safely ignore the error messages shown. When you’ve done this, you can
skip the rest of this section.</p>
<p>If you’re using SpatiaLite 2.3, you’ll need to download a
database-initialization file and execute its SQL queries in your database.</p>
<p>First, get it from the <a class="reference external" href="http://www.gaia-gis.it/spatialite-2.3.1/resources.html">SpatiaLite Resources</a> page:</p>
<div class="highlight-python"><pre>$ wget http://www.gaia-gis.it/spatialite-2.3.1/init_spatialite-2.3.sql.gz
$ gunzip init_spatialite-2.3.sql.gz</pre>
</div>
<p>Then, use the <tt class="docutils literal"><span class="pre">spatialite</span></tt> command to initialize a spatial database:</p>
<div class="highlight-python"><pre>$ spatialite geodjango.db < init_spatialite-2.3.sql</pre>
</div>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">The parameter <tt class="docutils literal"><span class="pre">geodjango.db</span></tt> is the <em>filename</em> of the SQLite database
you want to use. Use the same in the <a class="reference internal" href="../../../settings.html#std:setting-DATABASES"><tt class="xref std std-setting docutils literal"><span class="pre">DATABASES</span></tt></a> <tt class="docutils literal"><span class="pre">"name"</span></tt> key
