Here are a few maps showing the boundaries of tectonic plates, specifically those around the Pacific Ring of Fire, helpfully traced out by 100+ years of earthquakes. I think about emergence sort of a lot, and this is convenient, because map making with big-ish data often results in blowing the dust off a larger-order system. … Continue reading Earthquakes and Emergence
Occasionally, you might want to give a map label a bit of a dynamic, dimensional, feel. Here is a technique I’ll use from time to time. Basic solid text… A copy of the text pasted behind, colored black, and given a Gaussian blur (looks like a dropshadow, but we’re not done yet)… The blurred text … Continue reading Envelope-Transformed Label Shadows
Here is a re-visit to the earthquakes map I made long ago. This is actually a much different process, though I’m happy to see the visual results are quite similar. The Pacific Ring of Fire… The Mid-Atlantic Ridge… Follow the how-to process here if you are interested in trying out the technique. Happy Mapping! John Continue reading Earthquakes
A few years ago I made a couple of small simple maps that showed the locations of tweets in the New York City area that mention either “love” or “hate.” And another that shows “happy” or “sad.” It was a fun way to visualize social media terms as a proxy for the sentimental terrain of … Continue reading Twitter Sentiment in NYC
The other day I wrote a Story Map describing my struggle to find affordable housing for my young family as a new cog in the workforce. It included a version of this map (here’s how to make it)… The mapped units are years of labor, at the current median income, to reach the median price … Continue reading How Many Years of Life Does That House Cost?
or, Cobbling Together Screenshots to Create Stereopairs If you ever had an “airphoto interpretation” class, and you are at least as old as me, then you likely peered through these suckers in a geography lab somewhere to view pairs of offset imagery in pseudo-3D. And, if you did it enough, you probably got to where … Continue reading 3D Brain Hack
Here is a walkability map of Seattle, showing areas reachable via a casual stroll within 1, 2, and 3 hours. The geography of Seattle is warped to conform to these walkability rings. In 2011 Kirk Goldsberry showed me a yellowed old draft manuscript of Waldo Tobler’s (covered in his hand-written notes; it was awesome) in … Continue reading Time Warp Walkability Map of Seattle
