Publicamundi Vector Plugin

Overview

The publicamundi_vector plugin allows users to upload vector geospatial data, and store and publish through OGC services.

Installation

1. Install required Debian packages

Install compression-related libraries

sudo apt-get install unzip unrar p7zip-full

Install GDAL libraries and Python bindings (at system-level):

sudo apt-get install python-gdal

2. Install plugin's requirements

pip install -r vectorstorer-requirements.txt

2.1. Install backend-specific requirements

Depending on the publishing backend you choose (i.e. geoserver or mapserver), a set of additional requirements must be met. So, according to your choice, run:

pip install -r vectorstorer-geoserver-requirements.txt

or

pip install -r vectorstorer-mapserver-requirements.txt

Configuration

1. Enable

This plugin requires publicamundi_dataset to be also enabled. To enable the plugin add this under ckan.plugins in the configuration file:

    ckan.plugins = ... publicamundi_dataset publicamundi_vector ...

2. Configure

The following should be set in the CKAN config:

    ckanext.publicamundi.vectorstorer.temp_dir = %(cache_dir)s/vectorstorer
    ckanext.publicamundi.vectorstorer.gdal_folder = (e.g. /usr/lib/python2.7/dist-packages)

Geoserver-specific configuration

    ckanext.publicamundi.vectorstorer.geoserver.url = (e.g. http://www.example.com/geoserver)
    ckanext.publicamundi.vectorstorer.geoserver.api_url = (e.g. http://geoserver.localdomain:8080/geoserver)
    ckanext.publicamundi.vectorstorer.geoserver.workspace = (e.g. CKAN)
    ckanext.publicamundi.vectorstorer.geoserver.username = (e.g. admin)
    ckanext.publicamundi.vectorstorer.geoserver.password = (e.g. geoserver)
    ckanext.publicamundi.vectorstorer.geoserver.datastore = (e.g. ckan_datastore_default)
    ckanext.publicamundi.vectorstorer.geoserver.reload_url = (optional e.g. http://geoserver.localdomain:5005/reload)

Geoserver workspace and datastore have to be created in advance. The datastore must be the same as the CKAN datastore database.

Mapserver-specific configuration

    ckanext.publicamundi.vectorstorer.mapserver.url = (e.g. http://ckan_services_server/cgi-bin/mapserv)
    ckanext.publicamundi.vectorstorer.mapserver.mapfile_folder = (e.g. /var/www/mapserv/mapfiles)
    ckanext.publicamundi.vectorstorer.mapserver.templates_folder = (e.g. /var/www/mapserv/templates)

If both mapserver and geoserver are both configured, default publishing server has to be specified:

    ckanext.publicamundi.vectorstorer.default_publishing_server= (e.g. mapserver)

If not set, geoserver will be used as the default publishing server.

3. Prepare Datastore

Enable the PostGis extension in the datastore database.
