Publishing geographic information on the web is a common requirement, and numerous platforms are available to support this need. Whether using commercial or self-hosted solutions, understanding the underlying workflows is essential for those looking to develop web map-based applications.

This workshop will focus on using QGIS and QGIS Server to create and publish web map applications. We will leverage QGIS, QGIS Server, and PostgreSQL to build a seamless and automated workflow.

On the server side, projects will be stored in a PostgreSQL database, where a database trigger will extract all necessary project information using PyQGIS. This process will automatically generate a fully functional web map application. QGIS Server will serve project layers, ensuring that any updates or customizations made in QGIS are reflected in the web app in real-time.

To maintain a consistent user experience between QGIS and the web, we will systematically review project components, including layers, column properties, and relationships. This ensures that users see the same content in their browser as they do in QGIS. Additionally, we will explore how QGIS layouts can be used for printing, including the ability to add custom content. The Atlas layout feature will also be demonstrated for generating print-ready maps of selected items or search results.

To simplify setup, the workshop will use a pre-configured Docker environment with all required software, making it accessible for beginners.

Prerequisites

To fully benefit from this workshop, participants should:
* Be familiar with QGIS
* Have basic Python knowledge (we will use PyQGIS, both in the QGIS console and externally)
* Be comfortable using Docker
* Be able to navigate a PostgreSQL client (e.g., pgAdmin or DBeaver)
* Have a basic understanding of how the web works
