Demo to publish your first QGIS project via G3W-SUITE

Demo  based on G3W-SUITE Dj22Py3 QGIS3.4

Stay tuned …. G3W-SUITE 3.0 (Dj2.2Py3 QGIS3.10) is coming!

The demo is based on a data package available in various formats (ShapeFile, SpatiaLite and PostGis).

Upload the ready-made QGIS project or use this data to create your cartographic project by defining all the aspects you prefer.

Access the G3W-SUITE Administration Panel, publish the QGIS project as WebGis service and manage tools and features.

Download data for the demo

Demo based on the follow services:




Demo on line

This version of G3W-SUITE is deployed for QGIS 3.4.x LTR version.

Download demo data and QGIS project, data avalaible in various formats:



A dataset copy is available on the G3W-Suite server.

Data are in EPSG: 3857. The projects are made with QGIS 3.4.x LTR.

Do you want use your data?

In the demo you can use your data only if you use data on a GeoDB.

Create a QGIS project optimized for publication

Open the QGIS project available on demo data.

You can modify alias, style, label, visibility interval…of the various layers.

For every layer you can decide which field has to be consultable from WebGis. For every field you can choose an alias.

Manage this aspect from the section Field on the Property window.

Property Layers

From the menù Project -> Property you can manage this aspetcs:


You can set Project title: it will be the header of the WebGis

N.B. Every projects must have a different title if you want that it be published on G3W-Suite. Remember to rename it if you have problems on upload.

Vector informations

Set which layer will be queryable from WebGis.

OWS Server

Set the Service capabilities as you prefer, this info will be published on Metadata section on the cartographic client.

Set the WMS Capabilities:

Advertised extent: initial map extension of the WebGis service

Any CRS restrictions: CRS available

Exclude composer: any print layout composer which must not be available on WebGis

Exclude layer: any layers which must not be available on WebGis

To speed up client responses, enable the Use layer ids as names option.

If you want active the auto-zoom function you have to check the Add geometry to feature response option.


If you want use bbox and polygon query tool, you have to set WFS Capabilities (only Published) for the queryable layers.

Now your QGIS project is ready to be published with G3W-SUITE.

Access the G3W-ADMIN Administration panel

Access to the G3W-SUITE application through Firefox or Chrome browsers:


Choose Login and use the demo profile:

user: demo

pwd:  g3w_demo123

Click on Admin section and the on Backend button.

In this section you can:

* create cartographic group: you will can use them to organize your WebGis services

*  publish your QGIS project

*  create and manage users

If you want to use the pre-configured mapping group, access to Demo Group and read directly the ‘Publish your QGIS project’ paragraph.

Demo Group is associated with EPSG 3857. All QGIS projects uploaded in this group must be associated with the same EPSG.

If you want to create a custom Group, follow the next instructions.

Create a new Cartographic Group

To create a custom Group, go to the left menu Cartogrhaphic Group  -> Add Group and fill out the dedicated form.

General Data

Name: title of the cartographic group (it will appear in the frontend)

Title: sub-title of the cartographic group (it will appear in the frontend  under the title of the group)

For free acces project choose Anonymus user.

GEO Data

SRID: define the projection system associated with this group.

Remember: inside this group you will can publish only QGIS projects with the same SR.

Demo Data are in EPSG: 3857

Base layers and default map features

Map controls: set the tools you want to make available to the user for all the WebGis services published within this group:

zoomtoextent: zoom to the initial extension

zoom: zoom in and zoom out

zoombox: zoom tool based on drawing a rectangle

query: classic info tool

querybbox: query using bbox (N.B. the queryable layers must be published as WFS services on the QGIS project)

querybypolygon: the query tool give info about the geometries of the layers that intersect the query polygon (Eg what intersects a cadastral parcel?). – N.B. the queryable layers must be published as WFS services on the QGIS project

overview: set the overview map

scaleline: presence of a scale bar

geolocation: geolocation tool (useful for tablet consultation)

streetview: Google StreetView on your map

nominatim: OSM-based address search tool

addlayers: tool to load on-fly (temporarily) additional layers on individual WebGis services (.shp, kml and geojson)
