SpatiaLite
|
||
|
|
==========
|
||
|
|
|
||
|
|
The `SpatiaLite module <https://www.gaia-gis.it/fossil/libspatialite/index>`_ for SQLite adds features for handling geographic and spatial data. For an example of what you can do with it, see the tutorial `Building a location to time zone API with SpatiaLite, OpenStreetMap and Datasette <https://simonwillison.net/2017/Dec/12/location-time-zone-api/>`_.
|
||
|
|
|
||
|
|
To use it with Datasette, you need to install the ``mod_spatialite`` dynamic library. This can then be loaded into Datasette using the ``--load-extension`` command-line option.
|
||
|
|
|
||
|
|
Installing SpatiaLite on OS X
|
||
|
|
-----------------------------
|
||
|
|
|
||
|
|
The easiest way to install SpatiaLite on OS X is to use `Homebrew <https://brew.sh/>`_.
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
brew update
|
||
|
|
brew install spatialite-tools
|
||
|
|
|
||
|
|
This will install the ``spatialite`` command-line tool and the ``mod_spatialite`` dynamic library.
|
||
|
|
|
||
|
|
You can now run Datasette like so::
|
||
|
|
|
||
|
|
datasette --load-extension=/usr/local/lib/mod_spatialite.dylib
|
||
|
|
|
||
|
|
Installing SpatiaLite on Linux
|
||
|
|
------------------------------
|
||
|
|
|
||
|
|
SpatiaLite is packaged for most Linux distributions.
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
apt install spatialite-bin libsqlite3-mod-spatialite
|
||
|
|
|
||
|
|
Depending on your distribution, you should be able to run Datasette something like this::
|
||
|
|
|
||
|
|
datasette --load-extenison=/usr/lib/x86_64-linux-gnu/mod_spatialite.so
|
||
|
|
|
||
|
|
If you are unsure of the location of the module, try running ``locate mod_spatialite`` and see what comes back.
