#30DayMapChallenge / Music

Where do people listen to music at commuting times? Using mobile phone data, we can observe that mostly when moving in public transportation! This bubble map shows mobile phone towers scattered around the city where Spotify is accessed to.

This is part of a WIP paper where we analyze several signals to infer the mode split (share of usage per mode of transportation) in Chilean cities.

#30DayMapChallenge / Movement: Change in mass transit share from 2012 to 2020 (before covid) in Santiago, Chile.

Public transport share was reduced almost eveywhere, except in areas near new metro/rail infra., as well as municipalities where we hypothesize that remote work has reduced motorized transport (thus increasing mass transit share relatively). We measured this using data fusion of mobile phone data and multiple official sources.

Made with #matplotlib and #geopandas, among other tools.

The Montreal AI Ethics Institute showcased our research on bot influence and political polarization at the bird site, with a case study on Chilean politics in 2020. It has a nice network visualization made with #matplotlib and #graphtool.

Interest in Mastodon/Twitter/other platforms according to Wikipedia pageviews:

On Nov. 6, Mastodon had 1.5X the interest (pageviews) of Twitter. It was its first day surpassing the interest on #Birdsite.

#30DayMapChallenge Day 8: OpenStreetMap

These small multiples show the urban infrastructure available in the Santiago Metropolitan Area (Chile), as seen from OSM in 2020.

Made using #Python, #geopandas and #matplotlib. OSM data was processed using the pyrosm library: https://pyrosm.readthedocs.io/en/latest/

This is a figure from a WIP paper where we integrate OSM data with mobile phone traces and official sources 🐦

#Introduction

I am a Chilean researcher on Urban Informatics and Computational Social Science. Most of my work is driven by visualization. I work mainly in Python.

My website is datagramas.cl and there you can find my visualization course based on the work by Tamara Munzner: http://datagramas.cl/courses/infovis/

I also have a repository with auxiliary functions and wrappers for Python, named aves: https://github.com/zorzalerrante/aves

Here I plan to connect with others and share my work in a focused way. Cheers!
