Kenneth Field has made no bones about his frustration with maps of the COVID-19 outbreak, many of which have presented data in ways that are at best misleading. A simple choropleth map isn’t always simple. He’s put his thoughts on what not to do, and what to do instead, in this Twitter thread, and followed that up with this article on the ArcGIS blog.

We live in an amazing time as far as cartography is concerned. Technology allows, and actively supports rapid, democratized mapping. Data, compiled and published in near real-time (if not actual real-time) encourages people to get their hands dirty to see what they can make.

When you throw in a developing human health story the ingredients are ripe for maps to take centre stage, as they have become with the ongoing coronavirus outbreak. Let’s take a look at how maps can help shape the narrative and, as concern (fear?) grows, how to map the data responsibly.
