Add a data to the map with the Isogeo plugin

To add a data directly to the map canvas, let's take a look to the options available in the "Add" column.

Here come the different use cases:

The dataset can be added through different options. User choose its preferred option in the drop-down list.

Fig. 24 : Data can be added through multiple ways

The dataset can be added through only one way. The column "Add" is a button.

The dataset can't be added: file is not reachable and any correct webservice is linked.

Criteria

File data

Metadata field Resource location of Identification tab has to contain the absolute path to the datafile.

This path must be reachable:

by the system user who launched QGIS (read);
from the machine if the data is located on a local network.

Cache

To improve performances, the plugin embed a minimalist cache system storing the unreachable paths. To empty the cache, click on the dedicated button in settings tab.

Supported formats

PostGIS

A PostGIS table can be added when:

the connection to the database has been already set in QGIS
the option "Save username and password" has been choosen
the metadata has been created by the Isogeo Scan

Geographic webservices

Plugin supports webservices layers which have been associated to metadata.

Supported services

Web Feature Service (WFS)
Web Map Service (WMS)
Web Map Tile Service (WMTS)

Important note Be careful, if service layer title, description or style name contains any special characters, it won't be possible to display it. It's a QGIS issue and related to a bad encoding management in PyQGIS.
