Installing Spatialite
|
|
=====================
|
|
|
|
`SpatiaLite`__ adds spatial support to SQLite, turning it into a full-featured
|
|
spatial database.
|
|
|
|
Check first if you can install Spatialite from system packages or binaries. For
|
|
example, on Debian-based distributions, try to install the ``spatialite-bin``
|
|
package. For Mac OS X, follow the
|
|
:ref:`specific instructions below<spatialite_macosx>`. For Windows, you may
|
|
find binaries on `Gaia-SINS`__ home page. In any case, you should always
|
|
be able to :ref:`install from source<spatialite_source>`.
|
|
|
|
When you are done with the installation process, skip to :ref:`create_spatialite_db`.

|
|
|
|
Installing from source
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
:doc:`GEOS and PROJ.4</ref/contrib/gis/install/geolibs>` should be installed
|
|
prior to building SpatiaLite.
|
|
|
|
SQLite
|
|
^^^^^^
|
|
|
|
Check first if SQLite is compiled with the `R*Tree module`__. Run the sqlite3
|
|
command line interface and enter the following query::
|
|
|
|
sqlite> CREATE VIRTUAL TABLE testrtree USING rtree(id,minX,maxX,minY,maxY);
|
|
|
|
If you obtain an error, you will have to recompile SQLite from source. Otherwise,
|
|
just skip this section.
|
|
|
|
To install from sources, download the latest amalgamation source archive from
|
|
the `SQLite download page`__, and extract::
|
|
|
|
$ wget https://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
|
|
|
|
Next, run the ``configure`` script -- however the ``CFLAGS`` environment variable
|
|
needs to be customized so that SQLite knows to build the R*Tree module::
|
|
|
|
$ CFLAGS="-DSQLITE_ENABLE_RTREE=1" ./configure
|
|
$ make
|
|
$ sudo make install
|
|
$ cd ..
|
|
|
|
__ https://www.sqlite.org/rtree.html
|
|
__ https://www.sqlite.org/download.html
|
|
|
|
.. _spatialitebuild:
|
|
|
|
SpatiaLite library (``libspatialite``)
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Get the latest SpatiaLite library source bundle from the
|
|
`download page`__::
|
|
|
|
$ wget http://www.gaia-gis.it/gaia-sins/libspatialite-sources/libspatialite-4.1.0.tar.gz
|
|
$ tar xaf libspatialite-4.1.0.tar.gz
|
|
$ cd libspatialite-4.1.0
|
|
$ ./configure
|
|
$ make
|
|
$ sudo make install
|
|
|
|
.. note::
|
|
|
|
For Mac OS X users building from source, the SpatiaLite library *and* tools
|
|
need to have their ``target`` configured::
|
|
|
|
$ ./configure --target=macosx
|
|
|
|
__ http://www.gaia-gis.it/gaia-sins/libspatialite-sources/
|
|
|
|
.. _spatialite_macosx:
|
|
|
|
Mac OS X-specific instructions
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To install the SpatiaLite library and tools, Mac OS X users can choose between
|
|
:ref:`kyngchaos` and `Homebrew`_.
|
|
|
|
KyngChaos
|
|
^^^^^^^^^
|
|
|
|
First, follow the instructions in the :ref:`kyngchaos` section.
|
|
|
|
When :ref:`create_spatialite_db`, the ``spatialite`` program is required.
|
|
However, instead of attempting to compile the SpatiaLite tools from source,
|
|
download the `SpatiaLite Binaries`__ for OS X, and install ``spatialite`` in a
|
|
location available in your ``PATH``. For example::
|
|
|
|
$ 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
|
|
|
|
Finally, for GeoDjango to be able to find the KyngChaos SpatiaLite library,
|
|
add the following to your ``settings.py``::
|
|
|
|
SPATIALITE_LIBRARY_PATH='/Library/Frameworks/SQLite3.framework/SQLite3'
|
|
|
|
__ http://www.gaia-gis.it/spatialite-2.3.1/binaries.html
|
|
|
|
Homebrew
|
|
^^^^^^^^
|
|
|
|
`Homebrew`_ handles all the SpatiaLite related packages on your behalf,
|
|
including SQLite3, SpatiaLite, PROJ, and GEOS. Install them like this::
|
|
|
|
$ brew update
|
|
$ brew install spatialite-tools
|
|
$ brew install gdal
|
|
|
|
Finally, for GeoDjango to be able to find the SpatiaLite library, add the
|
|
following to your ``settings.py``::
|
|
|
|
SPATIALITE_LIBRARY_PATH='/usr/local/lib/mod_spatialite.dylib'
|
|
|
|
.. _Homebrew: http://brew.sh/
|
|
|
|
.. _create_spatialite_db:
|
|
|
|
Creating a spatial database for SpatiaLite
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
When running ``manage.py migrate`` with a SQLite or SpatiaLite database, the
|
|
database file will be automatically created if it doesn't exist. Django will
|
|
also ensure that the spatial metadata are initialized in the database.
