Here is the result of a late afternoon diversion. The bathymetric data comes from the NOAA Great Lakes Environmental Research Laboratory. The aspect ratio is consistent with a 1920×1080 monitor so it might make an alright desktop image, if you are into that sort of thing. Quick process run-down, which will take as long to type … Continue reading Great Lakes Bathymetry
Well, coasts have always been especially interesting things on atlases and globes. Here are two throwback methods for giving coastal areas a bit of offset contrast and a sense of depth and abrupt texture. Coastal stippling helps land features rise off the map a bit, via a denser occurrence of pen-tip ink deposits near coasts, … Continue reading Hand-Drawn-ish Coastal Effects
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?
