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...

Previously, we mapped neo4j spatial nodes. This time, we want to take it one step further and map relationships. A prime example, are the relationships between GTFS StopTime and Trip nodes. For e...

In the recent post Setting up a graph db using GTFS data & Neo4J, we noted that — unfortunately — Neomap is not an option to visualize spatial nodes anymore. GeoPandas to the rescue! But firs...

Today, I want to point out a blog post over at https://carto.com/blog/analyzing-mobility-hotspots-with-movingpandas written together with my fellow co-authors and EMERALDS project team members A...

In a recent post, we looked into a graph-based model for maritime mobility data and how it may be represented in Neo4J. Today, I want to look into another type of mobility data: public transport ...

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...

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...

Cartographers use all kind of tricks to make their maps look deceptively simple. Yet, anyone who has ever tried to reproduce a cartographer’s design using only automatic GIS styling and labelin...
This post aims to show you how to create quick interactive apps for prototyping and data exploration using Panel. Specifically, the following example demos how to add geocoding functionality base...
