G3W-SUITE: publishing and managing cartographic QGIS projects on the web


Published on

G3W-SUITE is a modular, client-server application for managing and publishing interactive QGIS cartographic projects of various kinds in a totally independent, simple and fast way.
The application can organize cartographic contents in a hierarchic way, helping the content management in structured contexts, such as public institutions, parks, companies etc. 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. 4
Its main components are the one for basis administration, G3W-ADMIN , and the visualization client for cartographic contents G3W-CLIENT.
G3W-SUITE and, in particular G3W-ADMIN and G3W-CLIENT modules, are released on GitHub with Mozilla Public Licence 2.0 https g3w-suite

G3W-SUITE: publishing and managing cartographic QGIS projects on the web

  1. 1. 1 Publishing and managing cartographic QGIS projects on the web W.Lorenzetti1 , L.Lami1 , F.Boccacci1 1 Gis3W GIS e WebGis OS Solutions
  2. 2. 2 Who we are? Gis3W is an Italian IT company with a core business on developing web and webgis applications. Gis3W was created in 2009 by main partners Walter Lorenzetti and Leonardo Lami. Over the years other members and collaborators joined in Gis3W. At the moment the main stable members are: Walter Lorenzetti Server-side developer System administrator Leonardo Lami QGIS/GIS User Expert QGIS Edu teacher Sales manager Customer front-end Francesco Boccacci Front-end developer
  3. 3. 3 Origins and objectives of the project ✔ have a software able to publish QGIS cartographic projects on a WebGIS client, in total autonomy and in simple and fast way ✔ can organize cartographic contents in a hierarchical way: Cartographic MacroGroups and Cartographic Groups; ✔ access control systems based on a configurable hierachic user profiling system for administration and consultation of projects ✔ develop dedicated modules that could be managed, from the point of view of access and use, in a profiled way
  4. 4. 4 G3W-SUITE: the project The result of our work is an application available in Open Source mode, under MPL license, on GitHub repository
  5. 5. 5 Components of the Suite G3W-SUITE is a modular client-server application for the publication and management of QGIS cartographic projects, consisting of 2 components: ✔ G3W-ADMIN: Administration component (project management, ACL, OGC proxy server, API rest server)1 ✔ G3W-CLIENT: Cartographic client for consultation and interaction with OGC services2 Optional modules ✔ Front-end geographic portal: access to information, thematic groups and WebGis services3 ✔ Caching Module: tile caching module for single layer powerd by TileStache4 1) 2) 3) 4)
  6. 6. 6 Technological Stack Icons made by Oliver ( from are licensed by CC 3.0 BY G3W-CLIENT developed with reactive tecnology by Vue.js G3W-ADMIN developed in Python 2 using Django QGIS-Server 3.4.X LTR as OGC services server PostgreSQL or SQLite for the management of suite data PostGIS, SpatiaLite or file system to store cartographic data
  7. 7. 7 User upload QGIS project, set ACL and other options through the G3W-ADMIN GUI Standard workflow G3W-ADMIN stores in DB info about project , projet layers etc. On bootstrap G3W-CLIENT calls init API On init API G3W-ADMIN sends project stored data and get extra information data through a GetProjectSettings to QGIS server After bootstrap G3W-ADMIN works as proxy for OGC services requests
  8. 8. 8 G3W-ADMIN The Administration interface G3W-ADMIN is a graphical user interface for dynamic definition parameters for G3W-CLIENT API REST configuration The administration system makes the user independent in publishing and managing WebGIS services
  9. 9. 9 G3W-ADMIN The Administration interface Creating thematic and cartographic Groups and MacroGroups to manage WebGis services in a structured way Creating single and group users that can be associated to different roles (admin, editor I, editor II, viewer) Publishing QGIS projects as webgis services, accompanied by logos, description and definition of access credentials Activating specific functional modules linked to single web services with ACL for users and user groups Managing published webgis services (search tools, editing, layers download)
  10. 10. 10 Settings inherited directly from QGIS projects Many graphic / functional aspects of the WebGis publication derive directly from QGIS 3.4.x projects ✔ Title of the project and therefore of the WebGIS service ✔ General settings of the service and the features of the single layers (activation scale, published attribute fields, display order and activation status, etc...) ✔ WMS service settings: publishing extension, SR restrictions and list of print layouts and layers to be excluded in the publication ✔ WFS service settings of the individual layers (bbox e polygon query) ✔ Print layouts available ✔ Attribute form structure and editing widget ✔ 1:1 and 1:n relation info
  11. 11. 11 G3W-ADMIN The Administration interface: layers Creating search tools, inheritable from the same layer in other projects Managing cache Single layer tiling through optional g3w-admin caching module Allowing layer download in shape file format Enabling editing on line (with attribute form structure and widget inheritable from QGIS projects) Enabling / disabling WMS legend Defining editing geographical constraints for each users enabled
  12. 12. 12 G3W-CLIENT The WebGIS Client Based on a modular approach, it allows to have an interface that adapts to the management of the currently available modules (eg print, search, editing, etc. ..) and future ones, in the simplest and clearest way for the final user
  13. 13. 13 G3W-CLIENT The WebGIS Client: features Browse the interactive cartography Various methods of interrogation (puntual, bbox, polygon) 1:1 e 1:n relation data defined at the QGIS project level Consultation of multimedia links and images preview Changing WebGis service maintaining extension and scale Print tool with layouts defined in the QGIS project Consultation of the attribute table with pagination system geolocation, on-the-fly external layer upload system Attribute form inherited from QGIS project Simple metadata inherited from the General Capabilities Use search tools created in G3W-Admin Video link
  14. 14. 14 ✔ work directily on DB by custom API (no WFS-T) ✔ permissions can be defined at the level of single layer ✔ feature-lock for multi-user editing ✔ user-settings snap mode ✔ geographical constraints based on other layers and settable for individual or group users Editing on line module
  15. 15. 15 ✔ attributes form inherited from the settings on the QGIS project (tabs, sessions …) ✔ editing widget inherited from the QGIS project: drop-down menu, calendar, checkbox, pick- layer, value map... ✔ editing on tables related also through 1:n relations based on the QGIS project settings Editing module Video link

  17. 17. 17 Future developments ✔ Python migration from 2 to 3 (within the end of the year) ✔ Use of QGIS3 API ✔ Release of editing module into the core or as optional module (in the next few weeks) ✔ Implementation of geographic analysis modules via WPS service (within the end of the year) ✔ Release of a CSW service by integrating pycsw as an optional module (within the end of the year)
