T. Jennings Anderson
Welcome to my node on the net. I’m currently a PhD student of Computer Science in Human Centered Computing at the University of Colorado Boulder.
I am a research assistant with Project EPIC (Empowering the Public with Information in Crisis), working with Professors Leysia Palen and Ken Anderson. My research emphasis is in Crisis Informatics, where I study the use of social media and social computing platforms during disasters. Specifically, I look at the creation of Volunteered Geographic Information (VGI) during times of crisis, focusing on both OpenStreetMap and Twitter.

OSM Node Density Martin Raifer's osm-node-density scripts create beautiful visualizations of the density of nodes in the OpenStreetMap database. I used his scripts and re-implemented the visualization with mapbox tiles and mapbox-gl to allow for smoother zooming.
