G3W-SUITE and QGIS integration: state of the art, latest developments and future prospects
Walter Lorenzetti

G3W-SUITE is a modular, client-server application (based on QGIS-Server) for managing and publishing interactive QGIS cartographic projects of various kinds in a totally independent, simple and fast way.

Accessing administration, consultation of projects, editing functions and use of different modules are based on a hierarchic system of user profiling, open to editing and modulation.

The suite is made up of two main components: G3W-ADMIN (based on Django and Python) as the web administration interface and G3W-CLIENT (based on OpenLayer and Vue) as the cartographic client that communicate through a series of API REST.

The application, released on GitHub with Mozilla Public Licence 2.0, is compatible with QGIS LTR versions and it is based on strong integration with the QGIS API.

This presentation will provide a brief history of the application and insights into key project developments over the past year.

The developments affected both the administration and management component of the exposed WebGis services, both the aspects of interaction with web maps and their contents, as well as the aspects and functions related to online editing through integration with the QGIS API.

A specific development, specifically covered in another submission, concerns the integration with the QGIS Processing API in order to migrate the analysis models, created in QGIS via the ModelDesigner, to a web environment.

The talk, accompanied by examples of application of the features, is dedicated to both developers and users of various levels who want to manage their cartographic infrastructure based on QGIS.

G3W-SUITE and QGIS Processing API integration: your geographic analysis models on the web
Walter Lorenzetti

The integration between G3W-SUITE and QGIS extends, with the latest release, to the APIs relating to the QGIS Processing module, allowing the use of geographic analysis models, created in QGIS, in a Web environment.

G3W-SUITE is a modular, client-server application (based on QGIS-Server) for managing and publishing interactive QGIS cartographic projects of various kinds in a totally independent, simple and fast way.

The framework is characterized by strong integration with the QGIS API in relation to numerous aspects: project management, data access, editing and much more.

A specific development concerns the integration with the QGIS Processing API in order to migrate the analysis models, created in QGIS via the ModelDesigner, to a web environment.

The new module is dedicated to the creation of geographic analyzes on the web and it is based on the automated analysis models prepared on QGIS through the Processing ModelDesigner.

During the presentation, both the aspects of interactions with the APIs and the workflow to allow the association of the analysis models with the published WebGis services and their use on the web will be described.

Finally, the limits of the current integration and future developments dedicated to simplifying the creation of personalized geographical analyzes on web maps will be described.
