Management and organization of geographic data and QGIS projects

This section describes how to organize QGIS data and projects locally and how to synchronize them on the server environment for publication purposes

Thanks to the integration with the APIs of QGIS it is now possible to manage the main formats (geographically and not) supported by QGIS Server:

  • reading and editing mode

    • PostGreSQL/PostGis

    • Oracle Spatial (compiling QGIS Server)

    • SQLite/SpatiaLite

    • GeoPackage

    • ShapeFile

  • reading mode

    • SQL Server

    • Virtal layer

The suite also allows you to manage in consultation ed editing:

  • simple join data

  • 1:N relation data

Data on DB Server

If your geographical data are stored on Server DB, it will be sufficient to allow access to the DB from the IP address on which the application is installed.

Data on SpatiaLite or OGR format

If your geographical data are stored on SpatiaLite or on physical files (.gpkg, .shp, .kml, .tif…) located on your local PC, you will need:

  • organize data and projects in predefined localy directories and subdirectories

  • upload/synchronize geographic data to the corresponding folder located on the server where the application is installed

Of course, mixed solutions with geographical data on PostGreSQL/PostGis, SpatiaLite and other formats will also be possible.

Organization of data and projects

Data on physical files and / or on GeoDB SpatiaLite and QGIS cartographic projects must be organized in compliance with the following indications:

  • a main directory named and positioned in according to need’s user

    • a project_data sub-directory that must contain the geographic data used for the various cartographic projects, such data can also be organized in subdirectories with no nesting limits.

    • a projects sub-directory that must contain the QGIS cartographic projects (.qgz or .qgs files)


NB: The name of the local directory dedicated to geographic data must correspond to the name defined for the DATASOURCE_PATH variable set during installation. See dedicated paragraph.

That directory is also used to contain images used in the print layouts associated with the QGIS cartographic projects.

Geographic data synchronization on the server

The data stored in the local project_data directory must be synchronized on the server where the G3W-SUITE application is installed.

The geographic data stored in the local project_data folder must be loaded, reflecting any subdirectory structure.

To synchronize your data access to the Administration panel of G3W-ADMIN and click on the Configurations icon _images/iconconfiguration.png located in the upper right corner.

Choose the File Manager item in the linked menu.



Using this tool it is possible to manage the physical geographic data on the server in a simple and intuitive way.

The root directory of the File Manager corresponds to the local project_data directory

It will therefore be necessary, in the case of using geographic files on the file system, to synchronize the contents of the local project_data directory (and any sub-directories) before proceeding with the publication of QGIS projects.

Two specific directories can also be created within the root directory of the File Manager:

  • media_user: a directory exposed on the web, to store your multimedia files

  • svg: a directory to store extra SVG icons used your QGIS projects

All the directories can be organized in subdirectories with no nesting limits.

NB: The names of these directories are defined by the basic settings set during the installation of the suite. See dedicated paragraph.


The example shows the case in which in the local project_data directory there are two directories (geopackage and spatialite) in addition to the two system directories (svg and media_user).
