GIS ecosystem

The QGIS ecosystem gathers:

• Mobile applications > QField & Mergin
• A processing engine to run algs > QGIS Processing
• A GIS Server > QGIS Server

QGIS Server

• Extensible with Python plugins
• Additional requests: GetPrint, GetLegendGraphics as JSON, etc

Lizmap Web Client uses the power of QGIS Server to bring maps in your browser

Lizmap Web Client

Prepare your projects on QGIS desktop / publish them with Lizmap

• FREE: opensource > Mozilla Public Licence (MPL 2.0)
• SIMPLE: Generates web maps for any QGIS project - No Code web app publication
• SECURE:
  • acts as a Proxy to QGIS Server
  • has a Web admin panel to manage users, rights, configurations
• POWERFUL:
  • many features and tools are available: editing, printing, attribute table, search, spatial filter, etc.
  • extensible with JavaScript or Modules
• MATURE 12 years of active development in QGIS Server & Lizmap Web Client

QGIS & Lizmap Web Client

Lizmap Web Client - some key features

• Manage rights on repositories, projects, layers, features, tools
• Rich editing forms for PostgreSQL layers / expressions for constraints
• Printing: QGIS print layout / Feature-based atlas PDF export
• Dataviz - show charts based on your data (pie, bar charts)
• QGIS relations: parent & child features / cascading filter

QGIS Lizmap extension - An overview

The Lizmap extension allows:

• to easily configure the QGIS project to publish,
• to choose which tools must be activated in your published map:

QGIS Lizmap extension - project validation

A growing set of validity rules

• security: PostgreSQL SSL connection, services
• performance: trusted project, estimated metadata, provider geometry, simplification, raster pyramids
• good practices: primary keys, needed indexes
• issues prevention: duplicated layers, proprietary format (ECW)

Lizmap 3.7 : layer tree

• Allow to check/uncheck the layer symbology rules independently
• A complete rework of the layer tree with modern Javascript object oriented code

Lizmap 3.7 : Printing layouts

• Allow to choose which layouts are published
• Add rights management per layout
• Configure default values for options: output format, resolution
• Allow to use a user-defined icon for each layout
• Atlas is of course supported

Lizmap 3.7 : relations management improvements

Very useful when you have a relation between a parent layer (ex: roads) and a child layer (ex: road works)

• You can now easily create a new child feature from the parent information panel
• The parent editing form respects the QGIS Drag&drop form layout

Lizmap 3.7 : Drawing improvements

• New text labels items
• Display measurements: length, area, perimeter
• Toggle drawing constraints by angle/length from the previous node

Lizmap 3.7 : Improve PostgreSQL actions

Lizmap actions: run specific PostgreSQL queries and display results ->new project and layer contexts / Run an action programmatically with JavaScript

Lizmap 3.8 - new features

• Render all the checked layers as a single image
• New management of the N to M relations data editor
• Ability to display specific layer features at startup when set in URL
• Improvement on the landing page content (logged and not logged user)
• Tooltip feature when hovering the map: allow to build rich content with QGIS expressions
• Popup: add toolbar for child features in the compact table view
• Data editing - Improve snapping functionalities
• New web component lizmap-features-table to display a compact list of features as a table
• A big thank to Faunalia for your contributions to this version

The new compact list of features

• a reusable component which shows a compact list of layer features
• 3.8: available only for user-defined HTML popup
• will be used by default in editing form and identify results (popup) in 3.9

Presentation module - Tell a story with Lizmap

• Create one or more presentation inside your maps
• Create slides with rich text and medias (images or video)
• Each slide can zoom to a specific area with a set of active layers

PgRouting - Find your way

• Based on the amazing PgRouting extension for PostgreSQL
• The module adds routing tools which help the user to find its way
• The routing graph is based on your data, not on a online API

WPS module - Run processing algorithms

• The power of QGIS processing toolbox inside Lizmap
• Each map has its set of allowed algorithms or models
• Run the algorithm: choose input values (buffer size, area code, etc.)
• Results are displayed whenever the algs ends (asynchronous run)
• Download produced outputs (layers, reports, etc.)

The future of Lizmap

Version 3.9:

• Generalize the use of the compact list of features
• Catch up with QGIS editing form capabilities
• Copy-paste geometries between tools (drawing, selection, identified feature)
• Integrate the presentation module inside Lizmap Web Client

Connect with our community !

• Organize online events to meet users and developers
• Gather user needs and maintain a roadmap with priorities
• Communicate more: transition from twitter to Mastodon & Linkedin, etc.
