Python

A spatial look at whether England’s housing crisis is really about too few homes, or too many empty rooms in the wrong places.

Here I show you an easy trick to retrieve completely custom networks from OSM, using Pyrosm, without extra packages and unnecessary conversions.

Here I post about the progress, struggle and success of working on project under GSoC 2021

This post will show you how you can calculate walking distances along OSM road network in matter of miliseconds.

Extracting data from XML and geocoding adresses and creating maps

An investigation into the identification network of global food hazards.

Introduction This notebook provides a simple example of the application of XGBoost Spatial Interaction model in python. For the purposes of this tutorial I will expect you to have some knowledge of Spatial Interaction Models and their purpose as well as some python skills. Yet, if you want to refresh a little or wish to learn, here is a list of relevant sources. Watch Maarten Vanhoof talking about what are the spatial Interaction Models and how they can be used here (6 min) Have a look at a list of some relevant literature in different fields here Look at the example of Spatial Interaction Model application in R from Adam Dennett Part1 and Part2 Look at how you can apply the the same method in python with SpInt package So what is the XGBoost?

Can we safely change a value of variable without casing harm? How is it going to affect the model results?

Do you have an Origin-Destination data, you want to crack on with Spatial Interaction Models, but you dont know the distances between Origins and destinations? This post will show you how to calculate them. You're welcomed.
