I think it needs more jpeg

This looks like a nasa image in their series “earth at night”. Looks like they do this every few years; they did one in 2012 and in 2016. Every once in a while I get a hankering to check it out, and for a while I could never remember what they were called.
Here’s the USA specific one from 2016: www.usgs.gov/…/photograph-united-states-night
Here’s the global version: earthobservatory.nasa.gov/features/…/page3.php

The community is called No Stupid Questions but apparently it does have stupid answers.

Maybe not, but it apparently helped mildly amuse significantly more folks than it pissed off so I’m happy with it.

To me it looks more like a Bertha.

My understanding is that’s literally what a big chunk of North America looks like at night, when viewed from space with a sufficiently long camera exposure.

The picture is clearly at the very least a composite, because there are zero clouds anywhere. I was skeptical whether it can be called a “photo”. Given how clear the unlit terrain is, even in the ocean around the Bahamas for example, I thought it must have been a visualization, or a photo of daytime terrain shaded blue and overlaid with a map of nighttime lights. But I found the actual source:
…nasa.gov/…/night-lights-2012-map
…nasa.gov/…/dnb_land_ocean_ice.2012.13500x13500.B…
It really is a (composite) photo taken by the Suomi National Polar-orbiting Partnership satellite, whose cameras are so sensitive they can see reflected moonlight and “the nocturnal glow produced by Earth’s atmosphere”, albeit partially in the infrared.This new image of the Earth at night is a composite assembled from data acquired by the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite over nine days in April 2012 and thirteen days in October 2012. It took 312 orbits and 2.5 terabytes of data to get a clear shot of every parcel of Earth’s land surface and islands.
The nighttime view of Earth was made possible by the “day-night band” of the Visible Infrared Imaging Radiometer Suite. VIIRS detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as gas flares, auroras, wildfires, city lights, and reflected moonlight.
I’m unsure though what “assembled from data” means exactly. At the very least the colors are artificial, shifted from the infrared-to-green range of the camera into human visual range. This page describes some more how the sensor functions, along with raw photos:

It kinda shows the dominance humans have over the planet. We affect nearly every part of it. Nearly everything is light up by our lights.
To the point where it’s visible from space. From space, it’s as if we have altered all of the night’s topography.

If you’re talking data viz, maybe a dichromatic chloropleth geo chart or a hot spot/density map?

Yeah heat map seems to be the most generic term for it.

I’m not sure what you’re looking for.
This is a composite satellite image of nighttime light sources.
I can’t think of anything unifying other than “satellite image”.
