We are going to deep dive into Network Analysis with QGIS!
Presentation Slide Deck contains links to step-by-step instructions and links to datasets.
This session will go through built-in tools and plugins in QGIS to do a variety of network analysis tasks. We will cover the following applications and solve them using QGIS and open data
- Locating the nearest health facility for a large number of addresses
- Choosing the optimal location of a new waste management facility
- Determining the service area of a public transit system
The session is suitable for beginners and we will cover network analysis from the very basics. The structure of the session is as follows
- Introduction to networks, graphs, and routing algorithms
- Building a network from a street network dataset
- Routing between 2 points - shortest and fastest path
- Routing between n:m points - distance matrix
- Location-Allocation Analysis
- Service Area Analysis
- Q & A
Ujaval Gandhi is a veteran QGIS user, trainer and blogger. Ujaval got his Masters in Geospatial Information Engineering from the University of Wisconsin-Madison, USA. He joined Google Inc. in 2005 as one of the early employees of the mapping group. He spent 15 years working on various projects at Google including leading Google's GIS teams in India. He started his company Spatial Thoughts in 2019 and now offers a wide range of training programs to address the learning needs of geospatial professionals.
Note that the stream may drop for a few minutes at around the 1h00 mark. Stick around and we will bring it up again ASAP.

Luis is going to give us a walk through of the advanced dashboard creation tool he has made for QGIS!

Host: Tim Sutton
Martin, Saber and Nyall are going to walk us through the cool new Point Cloud features coming in QGIS 3.18!

We will use OpenDroneMap to get point clouds from images. OpenDroneMap can run from docker, so you don't have to install anything (you must have docker, of course). We will use WebODM, which is ODM with a nice web interface.
We will cover the full life cycle, starting from surveying ground control points. Ground control points will be collected using an ArduSimple precise GPS with live corrections. It costs around 400 €. We will use SW Maps, made in Nepal. It is not open source. It is free and the author Avinab Malla answers emails. SW Maps enables the use of and eternal GPS and supports live differential corrections.
They we will fly using Pix4D Capture. It is not open source. It is free and there is a community support forum. Any equivalent software can be used to get the pictures.
We discuss some good practices for the flight, like flight height, image overlapping, camera angle, etc. Some flights will be made available using different configurations.
Then we run OpenDroneMap. OpenDroneMap is a huge software stack. Processing images with full resolution requires lots of RAM and takes time. We will see how easy is to use multiple nodes to run it (so you can take advantage of computers near by). Before using the point cloud in QGIS, we will briefly introduce some nice visualizations tools already available in ODM.
Finally, we will open the point cloud in QGIS.

Presenter: Hannah Dormido
Host: Tim Sutton
Hannah will share how she uses QGIS for work and for her hand-drawn maps. She’ll show us her map-making process, maps made with QGIS, and the hand-drawn maps (which started their lives as QGIS maps).
You can do this too! We really encourage others to follow our initiative, using the wiki page link below to organise your plans (just add a section below the last one). You can host virtual meetups in the Jitsi room, plan your next steps to take QGIS further down the road to world domination and much much more. We encourage language and region specific huddles, documentation improvement sessions, bug fixing, making beautiful maps, and working together to do amazing things with QGIS.
We would really love to see more events offered from our country user groups and broader user base. The content can be at any skill level and in any language you like, and the times can overlap if needed. So please feel free to organise your activities on this wiki page. The QGIS Open Day is also an ideal time to hold virtual country user group meet ups - please share your activities on the open day schedule, so that even people from outside of your country user group can benefit from your presentations. Contact me (see below) if you need help adding your events to the wiki page.
You can spread the word! We have prepared the following materials so that you may easily copy and paste the relevant contents to publish on your media platform of choice to let others know about these awesome events.
About QGIS Open Day
Dear QGIS Users
On Friday, 29 January 2021 we will be holding our monthly QGIS Open Day! What is a QGIS Open Day you may be wondering to yourself? It is an initiative to replace the wonderful community meetups we used to hold every six months when times were different. Like our in-person meetings, the event is organised on a principle of self-organisation and community participation.
