Trying John Nelson's tutorial to generate a prefecture map of Japan in "classic National Geographic sort of political style". Having so much fun playing with the symbology in ArcPro again

Academic vs. media representations of a new Antarctic under-ice dataset. The sequential (University of Grenoble-Alpes) palette emphasizes overall structure, divergent (BBC) emphasizes the extremes. From Science & the BBC/@erwanrivault.com www.science.org/doi/10.1126/ www.bbc.com/news/article... 📊

Map of Antarctica’s under-ice topography with a sequential color palette (viridis, which runs from dark blue (lowest elevations) through green to yellow (highest elevations)). This palette emphasizes the overall structure of elevation, but obscures the line of bedrock between above and below sea level.

The relatively "warm" yellow hues for high elevation also help them visually protrude from the "cool", low-elevation blues.

Map of Antarctica’s under-ice topography with a divergent color palette (blue shades represent areas below sea level, tan and brown areas above sea level). This clearly shows where the bedrock is below sea level. It also allows the map to blend seamlessly with ocean bathymetry.

Since most elevations are only modestly above or below sea level, and are relatively pale, added shaded relief helps accent the topography.

The BBC cartographers also included photos to help illustrate what the topography would look like without ice.

Geological map of Aso Volcano in Japan My knowledge on geology is probably layman level (got a B grade in an intro earth science course during undergraduate), but geological maps still fascinate me so much 🔗 www.gsj.jp/Map/EN/volca...

No idea why, but I love the greenish pale blue color of the palette in this choropleth map from The New York Times so much 🔗 www.nytimes.com/interactive/...

Happy New Year everyone! 🎆✌️ Was reading articles about the first sunrise of Japan (初日の出) and fell down a rabbit hole researching sunrise times on January 1 in cities across Asia and turned it into #MapInProgress

#30DayMapChallenge Day 29 - Raster Daytime/Nighttime temperature difference in Australia, Jan 2025 Wanted to map something about the country after my trip last month, and land surface temperature is always a good starting point for exploring a place you don't know much about

#30DayMapChallenge Day 14 - OpenStreetMap Comparing peaks in Hong Kong based on crowdsourced OSM data vs. official government data We don’t have a strict definition of when the top of a hill should be considered a peak anyway ¯\_(ツ)_/¯

Posting again after a 2-week social media break. Just returned from a holiday in Sydney and Melbourne last week. Great weather, great cities, great national parks, great food. First time in Australia and will definitely come back.

Hi all urbanists here: I will be visiting Australia (Sydney and Melbourne) shortly, are there any transport planning / active travel / architecture / urban planning projects you'd recommend for a site visit?

See my commentary in @nytimes.com in re climatic & non-climatic factors pushing down home prices (always excellent work of @benkeys.bsky.social & P. Mulder) Amazing to see how far prices have tanked in Nola. Good News: homes w/ Fortified Roofs are holding their value. www.nytimes.com/interactive/...

Changes in the insurance market have started to affect home prices in the most disaster-prone areas, new research finds, pushing some homeowners’ finances to the breaking point.

#30DayMapChallenge Day 19 - Projections 19 projected coordinate systems of Japan (JGD2011 Japan plane rectangular CS, I to XIX) shown together, with Tokyo being the centre point Don’t ask me what does this map means, I also have no idea what I’m doing

#30DayMapChallenge Day 17 - A new tool Testing out the {mapgl} package in #RStats with a zoom-in animation on Shibuya station, Tokyo The highlighted zones show 10-minute walking isochrones from each Yamanote Line station made for the previous map

#30DayMapChallenge Day 13 - 10 minute map Reachable areas within a 10-minute walk / 10-min isochrones of Yamanote Line (山手線) stations And yes, the map took much longer than 10 mins to make, sorry not sorry
