ckanext-spatial - Geo related plugins for CKAN

This extension contains plugins that add geospatial capabilities to CKAN, including:

• A spatial field on the default CKAN dataset schema, that uses PostGIS as the backend and allows to perform spatial queries and to display the dataset extent on the frontend.
• Harvesters to import geospatial metadata into CKAN from other sources in ISO 19139 format and others.
• Commands to support the CSW standard using pycsw.

Note: The view plugins for rendering spatial formats like GeoJSON have been moved to ckanext-geoview.

Old documentation, including installation instructions, can be found at:

https://docs.ckan.org/projects/ckanext-spatial/en/latest/

For TWDH installation (CKAN 2.9.5 on Ubuntu 20.04 LTS), first ensure you have ckanext-harvest installed using a Redis backend.

Afterwards, do the following:

. /usr/lib/ckan/default/bin/activate
sudo apt-get install postgis
sudo -u postgres psql -d ckan_default -f /usr/share/postgresql/12/contrib/postgis-3.0/postgis.sql
sudo -u postgres psql -d ckan_default -f /usr/share/postgresql/12/contrib/postgis-3.0/spatial_ref_sys.sql
sudo -u postgres psql -d ckan_default -c 'ALTER VIEW geometry_columns OWNER TO ckan_default;'
sudo -u postgres psql -d ckan_default -c 'ALTER TABLE spatial_ref_sys OWNER TO ckan_default;'
cd /usr/lib/ckan/default/src
git clone https://github.com/dathere/ckanext-spatial
cd ckanext-spatial
pip install -r requirements.txt
sudo apt-get install python3-dev libxml2-dev libxslt1-dev libgeos-c1v5
python setup.py develop

then add ckanext-spatial to your ckan.ini plugins:

ckan.plugins = ... twdh_theme harvest ckan_harvester spatial_metadata spatial_query twdh_schema ...

and restart CKAN:

sudo service supervisor reload
