QGIS Open Day – QHF March 2021
Join in on the QGIS INTEGRATED open day. Our amazing lineup of presenters will show you how QGIS can work in a network with other software and programs to create dynamic and sharable spatial data, maps, and systems.
If you would like to discuss topics on our QGISOpenDay, please add sections below for each discussion along with the proposed time and agenda.
Simply join the meeting on Jitsi and say hi! https://meet.jit.si/QGISOpenDay
To keep up to date with QGIS Open Day events, please join the Telegram channel
Virtual events will be taking place online (see links below) and in the telegram chat room, and with many events also being live-streamed on YouTube. See the individual event descriptions below for an indication of where to join each event.

QGIS Plugin – Multilayer Select #QGIS
Multilayer Select (QGIS plugin)
Add new selection tools that work across layers.
- Select by Click
- Select by Rectangle
- Select by Polygon (and freehand while the mouse is pressed)
- Select by Freehand
- Select by Radius
- Add/Remove to/from selection when pressing Shift/Ctrl
- Select all features from all layers
- Invert all features
- Select by expression
One can also exclude some layers, that will not be used by the mutli selection tools
- Selection color: effect icons, rubberband, and features
- Set active..: If enabled and the active layer has no selected feature, change the active layer to the first layer with at least one selected feature
- Replace default action: If True, replace the QGIS selection tool with the multilayer selection tools. Else, add the multilayer selection tools in their own toolbar
- Display settings action on the toolbar
- Included Layers: list the vector layers in the current project. Unchecked layers will be ignored by the multilayer selection tools (useful for ignoring a vector basemap for instance).
- If Exclude hidden layers is checked (default), the selection tools will not select or deselect any feature belonging to hidden layers (unchecked in the QGIS layer tree view)
- If Always include an active layer is checked (default), the active layer will not be ignored even if it is unchecked in the list.

Import maps of Azeroth from game “World of Warcraft” in QGIS
QGIS Plugin importing spatial data from World of Warcraft game to your computer!
The plugin can import both raster and vector data by running WFS and WMS requests to GeoServer. Currently, it’s fairly simple and can be considered as proof of concept, but in the future can be easily developed by adding more importable layers, like rivers, dungeon locations, mountain ranges, etc.

Visualize nuclear energy in the world using the Nuclear Energy Plants Radiations plugin #QGIS
Nuclear Energy Plant Radiation Plugin
This project was developed on the course of the Geographic Information System (GIS) of the master’s degree program in data science at the University of Salerno. The goal of this project was develop a python plugin for the software Quantum GIS (QGIS) in order to visualize on the open street map all nuclear energy plant in the world. This plugin use the mqtt protocol for receive of radiation data from sensors in order to dinamically visualize it on the map. In order to clarify the visualization of the radiation data, a heat map was created and used. The plugin uses fake radiation, it simulates that the data comes from real sensors.

Create a section profile of a DEM using the D.E.M. Slicer plugin #QGIS
It is a simple cutting tool (in slices) of DEM data, to draw pretty postcards, for lovers of reliefs.
The principle is to build a series of altitude profiles (lines or polygons), to juxtapose them to give the illusion of a 3D view. Here, no calculation of the atmospheric refractive index, no consideration of the Earth’s curvature … just a little geometry, and the styles do the rest. The resulting layers are positioned where you want, the coordinate system used is that of the map (prefer 3857 rather than 4326 -in degrees-).
The offsets (varied according to the parameters chosen) in height of each cut simulate parallel or perspective views, a ‘radial’ vision attempts to get closer to the vision that an observer can have.
A ‘ridge line’ calculation enhances the reliefs.
- have an altitude raster image. different possible sources: https://dwtkns.com/srtm30m/, https://opendem.info, https://grindgis.com/data/free-world-dem-data
- to work in a projection whose unit coincides with the altimetric unit of the DEM (3857, WGS 84 / Pseudo-Mercator for example).
