It’s a light pollution map!

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”.

Looks like a jpeg to me

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: https://www.usgs.gov/media/images/photograph-united-states-night

Here’s the global version: https://earthobservatory.nasa.gov/features/NightLights/page3.php

Satellite image at night.

Nighttime satellite light map?

I named it Gerald.

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. This specific image may be composed of many exposures, but it’s not a cartogram or something; it’s a composite photograph.

Mostly you’re seeing electric lighting, which is clustered around places where people live and have the resources to light up their buildings and streets – so that people can see, drive, and be safe at night.

Looks like a planning map for high speed rail to me

idk, a light map? you trying to Google it? or just for the trivia knowledge?

!solved

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

What color is this dress?
