#MapsInTheWild overview map of Naoshima, Teshima and Inujima in the Seto Inland Sea

Love the use of RGB colours for each island and that circle zoom-in of Naoshima Port in the top left so much

Weather of my flight from Japan back to Hong Kong yesterday was too tremendous that I took tons of photos of some iconic mountains

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

Map of Antarcticaโ€™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 Antarcticaโ€™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.

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.

Geological map of Aso Volcano in Japan

#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

We donโ€™t have a strict definition of when the top of a hill should be considered a peak anyway ยฏ\_(ใƒ„)_/ยฏ

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?

Rising Home Insurance Premiums Are Eating Into Home Values in Disaster-Prone Areas (Gift Article) Changes in the insurance market have started to affect home prices in the most disaster-prone areas, new research finds, pushing some homeownersโ€™ finances to the breaking point.

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/...
