It’s my pleasure to share with you that Trajectools 2.0 just landed in the official QGIS Plugin Repository. This is the first version without the “experimental” flag. If you look at the plu...

The Trajectools toolbox has continued growing: I’m continuously testing the algorithms integrated so far to see if they work as GIS users would expect and can to ensure that they can be integra...

Trajectools development started back in 2018 but has been on hold since 2020 when I realized that it would be necessary to first develop a solid trajectory analysis library. With the MovingPandas...

Starting from 3.26, QGIS now supports .vtpk (Vector Tile Package) files out of the box! From the changelog: ESRI vector tile packages (VTPK files) can now be opened directly as vector tile layers...

In the previous post, we investigated how to bring QGIS maps into Jupyter notebooks. Today, we’ll take the next step and add basemaps to our maps. This is trickier than I would have expected. I...

Did you know that MovingPandas also supports local image coordinates? Indeed, it does. In today’s post, we will explore how we can use this feature to analyze bicycle tracks extracted from vide...

Today’s post is a geeky deep dive into how to leverage DVC (not just) data version control to track QGIS geoprocessing workflows. “Why is this great?” you may ask. DVC tracks data, paramete...

In the previous post, we — creatively ;-) — used MobilityDB to visualize stationary IOT sensor measurements. This post covers the more obvious use case of visualizing trajectories. Thus bring...

Today’s post presents an experiment in modelling a common scenario in many IOT setups: time series of measurements at stationary sensors. The key idea I want to explore is to use MobilityDB’s...
