If you want others to ponder something unusual, the least you could do is post a placemark so we could look for ourselves. Given the straight line formed by the left edge of the dots, my first guess would be some sort of contamination of the GE image. Remember Roger of Occam!
well, if it were only some imagery error, then it would be visible by one exact imagery date, but it is there on different imagery datasets. (e.g. check ZE imagery from 2016) ... (placemark attached, however a bit hard to spot since not highlighted with the purple strip of attachments as it were before.)

These are perpendicular to the slight slope to NW, so probably were made to change water runoff, also darkening of the dotted area could be sign of developed water supply of the soil, only it is another method tried out on the same plot. (?) (notice overlapping, where combination of the two techniques could be tested)
maybe this is too simple of a guess, but given its close proximity to a city. is it possible that this is a waste dump? simply burying the trash in sand might be easier than digging holes. and the regular structure may be a result of disposing trash in an orderly manner. althoe I doubt that small citys in Niger care about such an expensive systematic system of processing waste.
There are two common reasons for squares such as this, one is tree/shrub planting, either for agriculture or de-desertifcation experiments. or (if no vegetation is visible) simple de-desertification and dune stabilisation.
If you search the area to the ENE of M'hamid, Morocco you'll probably see some squares of rush-fences arranges in square grid pattern (M'hamid is south of the city of Zagora - it's the "end of the road" near the Morocco/Algerian border (only the tarmac/goudron - the roads/pistes continue)
The grids change shape as sand piles up over them so can change over time, but also look different depending on sun angles casting shade. Different regions use different styles and dimensions, some are experimental and less successful than others. They can also be used to catch windblown sand upwind (in the prevailing wind direction) of a settlement to prevent dunes forming and making iut uninhabitable
Recent example These look relatively new, compared to the almost-buried ones I saw closeby in around 1998. I;ll see if I can find the older ones for comparison. and will edit the post if I find them
20 years old or more, with agriculture traces Im pretty sure the ones I saw 20+ years ago where these faded ones. They appear to have been used for agricultural planting (olive or posibly argan trees) due to the traces of irrigation pipes (the North-South lines joning the dots in between the squares. Note how they gradually fade and walls of one orientation to the sun appear inconspicuous due to the sun angle. The tree crop appears to have failed (some bad drought years siince 1998) and the very clear shaped of recent sand fencing just north of the old ones, closer to the road. (with interesting diagonal lines too)
KitsuneFox: syzygy - posts I have made here do not receive much attention. I may do a detailed writeup of the now lost Edgemont Park in PA, one of the first electrified trolley parks in the world, but still debating. I'm missing 1 key bit of information.

KitsuneFox: Mount Wycheproof in Australia is the shortest recognized mountain on the world. It stands at 141 feet base to peak. A mineral named 'Wycheproofite' is mined near the location, and is the only known place it's found.

KitsuneFox: Mount Chimborazo in Ecuador is the highest mountain on Earth, as measured from the center of the planet. The peak is over 6,800 feet further away than Mount Everest, and is the closest land on earth to outer space.
