In R's mapgl package, use `add_image_source()` to add a terra raster to your map, then display it with `add_raster_layer()`.
Drape it over Mapbox's Standard style for built-in 3D!

#30daymapchallenge | Day 29 Raster | Algal Bloom
Raster isn’t my particular area of cartographic expertise… but here’s a stylization of Sentinel 2 imagery capturing a particularly gnarly algal bloom in May 2023. This particular event led to beach closures quite early in the summer season.

I'm sure it can be improved but I really like how it looks already!

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.
