Project: G3W-SUITE QPROCESSING

Release date: 13 December 2023

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

The setup flow is very simple:

1. 1. 1. set up you analysis model on QGIS using the ModelDesigner

      2. upload the model file (.model3) to G3W-SUITE and associate it with one or more WebGis projects

      3.  the model is used directly on the web side, displaying and downloading the results created

The analyzes are performed in “on line” mode.  At the end of the analysis flow, the results will be uploaded to the map (if geographical) and available for download.

Even if the analysis operations to be performed are limited to those performed by a single analysis module, it is necessary to implement a model using the ModelDesigner. This is also to distinguish the options set beforehand from those available to the user.

QGIS Model Builder features and settings

Input type supported

• • • Boolean
    • Distance
    • Fields Mapper
    • Number
    • Raster Layers
    • Vector Features (selected feature of a layer)
    • Vector Layers

It is also possible to define project layers as default input of the individual modules.

This option limits the use of the model to a specific project or to projects containing the layers defined as inputs.

Additional input types will be integrated into the next version of the module!

Managed algorithms

All QGIS modules, considering limitations in handling options/inputs associated with managed type of inputs

Further settings

• • • input order in the model form
