Median Generations by County (2023) Another version of my previous map. I used the
#QGIS
2.5D symbology with a standard choropleth. It is a little confusing to use, but I think I get the gist of it now. The counties are extruded by population.

Five classes I took in college. - Intro to Art (I still think about this class) - United States History in the 1970s - Climatology - German Fairly Tales - Microeconomics (yuck) Honorable mention for statistics. Also, taking an econ class dropped my opinion of econ into the toilet. Lol

I made a Median Generations map of the US for a contest, but I missed the deadline. 😅 The generations are based on the median age of census tracts in 2023. The urban areas are tract centroids, and the rural areas were dasymetrically binned to a 10km grid.

For context, before 1980,
#Nashville
temperatures hit 0°F an average of once per winter. Because of
#GlobalWarming
, what used to be an annual event has only happened 4 times in the last 30 years. Similarly, before 1980 we got 12" of snow in an average winter. Since 2000, it's around 4".

This simple label took me over day to make. I am still learning expression builder in

. I needed the highest value for each feature from over one hundred attribute columns AND the name of the field name. The worst part is I don't know if I will use this info. lol

Labeling maps is a peaceful practice, and often is half the job of a cartographer. I'm sure seas will be drained and skies will be blackened so that AI can do it in our stead in a year or two, but for now, I always enjoy looking at a "map minus map" version of completed work.

A work-in-progress map of the Forests in the lower US. I haven't decided if I am going to display and label the National Parks and/or Forests yet. Things get pretty busy on the West Coast. The legend is going to be a nightmare and I am not looking forward to it. 😂

Arizona Joy Plot Map Testing out another method. Instead of applying the gradient across the entire feature layer, I applied a gradient to each individual plot line. This gives the plot lines a more 3D like effect. This is still a work in progress.

Can you tell that today is a solstice by the tilt of the Earth? Yes. At a solstice, the Earth's terminator -- the dividing line between night and day -- is tilted the most.

Dark mode maps are attractive & engaging, but present design difficulties. It’s harder for us to parse light on dark than dark on light, and the way we interpret variation in lightness as differences in transparency compounds the difficulty. 📊🗺️🎨 From:

Day 28 - Black The Longest Nights (2025) Polar night (+24 hr night) occurs just beyond the Arctic Circle. This is due to the Earth's gravitational pull on light. The ramp up from just beyond the Arctic Circle 67.4°N (24 hrs) to 67.5°N (11 days) is wild.
