G3W-SUITE

What is G3W?

G3W-SUITE is a modular client-server application designed for the management and publication of interactive map projects. It was created to offer a simple, fast, and autonomous solution for publishing cartographic projects developed with QGIS on a WebGIS client.

Built using the Django framework and written in Python, G3W-SUITE integrates the core components of QGIS to help users build and publish their own Geographic Information System (GIS) solutions in an intuitive way.

Core Technologies

G3W-SUITE is entirely based on well-established Open Source software components, centered around QGIS:

  • QGIS Desktop: For managing cartographic data, editing, and designing high-quality map projects.
  • QGIS Server: For publishing QGIS projects as Open Geospatial Consortium (OGC) services.


Current Compatibility:

G3W-SUITE version 3.9 is compatible with QGIS 3.34 LTR (both Server and Desktop).

Only the latest LTR (Long-Term Release) version of QGIS is supported.

Modular Architecture of G3W-SUITE

G3W-SUITE is composed of three primary modules:


  1. G3W-ADMIN

    • Administration interface for project management
    • Handles ACL (Access Control List)
    • Includes an OGC proxy server
    • Provides a REST API server


  2. G3W-CLIENT

    • A cartographic web client
    • Enables viewing and interaction with published OGC services


  3. Front-End Geographic Portal

    • Provides public access to thematic groups
    • Allows exploration of WebGIS services and related information


G3W Modules

Key Features and Capabilities

Through the G3W-SUITE web interface, users can:

  • Publish QGIS projects directly to the WebGIS environment in a structured manner
  • Organize WebGIS services into multi-level thematic and functional containers
  • Manage users and groups with customizable functional roles
  • Create and manage various search methods
  • Edit spatial data online
  • Extent capabilities by activating specific functional modules to extend.
  • Define access permissions for both services and functional modules per user

Version Compatibility and Branch Status

Currently, G3W-SUITE does not follow a traditional versioning system. However, the following branches are available, each aligned with specific versions of Python, Django, and QGIS:
