Modified for use with the vdoj_spatial field.

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.
• Plugins to preview spatial formats such as GeoJSON.

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

http://docs.ckan.org/projects/ckanext-spatial

• Developer mailing list: [email protected]
• Developer IRC channel: #ckan on irc.freenode.net
• Issue tracker

For contributing to ckanext-spatial or its documentation, follow the same guidelines that apply to CKAN core, described in CONTRIBUTING.

When re-initializing database after issuing paster db clean -c /etc/ckan/default/production.ini, it is necessary to issue: sudo -u postgres psql -d ckan_default -f postgis_resetup.sql Instead of issuing, sudo -u postgres psql -d ckan_default -f /usr/share/postgresql/9.1/contrib/postgis-1.5/postgis.sql

Then you can issue: sudo -u postgres psql -d ckan_default -f /usr/share/postgresql/9.1/contrib/postgis-1.5/spatial_ref_sys.sql

Note: there are existing checks in postgis_resetup.sql
