Several software must be installed :
- Postgresql (9.4 or higher, http://www.postgresql.org)
- Postgis extension (2.2 or higher, http://postgis.net/)
- QGis (2.12 or higher, www.qgis.org)
These systems are available for download on their respective website or can be found partly bundled together. It is up to the user to choose which version fits its needs and system.
When all these software are installed the TRS database needs to be installed by running the DB installation script, the user accounts have to be created and configured and the parameter tables have to be filled (default data are provided but this should depend on the user organisation).
For an autonomous installation all these elements have to be on the same computer, but alternatively PostgreSQL and PostGIS can be on another computer.
A connection has to be configured inside QGis to the TRS database, using the "ADD a Postgis layer" tool and providing the connection parameters.
Finally, the QGis project can be opened.
