July Puzzler

July 13th, 2021 by Adam Voiland

UPDATE — This puzzling image shows an abundance of agriculture in Andhra Pradesh. See the full image and story in our Image of the Day, published on July 17. 

Every month on Earth Matters, we offer a puzzling satellite image. The July 2021 puzzler is above. Your challenge is to use the comments section to tell us what we are looking at, where it is, and why it is interesting.

How to answer. You can use a few words or several paragraphs. You might simply tell us the location, or you can dig deeper and explain what satellite and instrument produced the image, what spectral bands were used to create it, or what is compelling about some obscure feature. If you think something is interesting or noteworthy, tell us about it.

The prize. We cannot offer prize money or a trip to Mars, but we can promise you credit and glory. Well, maybe just credit. Roughly one week after a puzzler image appears on this blog, we will post an annotated and captioned version as our Image of the Day. After we post the answer, we will acknowledge the first person to correctly identify the image at the bottom of this blog post. We also may recognize readers who offer the most interesting tidbits of information about the geological, meteorological, or human processes that have shaped the landscape. Please include your preferred name or alias with your comment. If you work for or attend an institution that you would like to recognize, please mention that as well.

Recent winners. If you’ve won the puzzler in the past few months, or if you work in geospatial imaging, please hold your answer for at least a day to give less experienced readers a chance.

Releasing Comments. Savvy readers have solved some puzzlers after a few minutes. To give more people a chance, we may wait 24 to 48 hours before posting comments. Good luck!

    Se observa un ambiente muy antropizado y por ende modificado, con pequeñas parcelas cultivadas y orientadas en diferentes direcciones, probablemente para evitar la perdida de humus y abastecidas por canales de riego y acequias, rodeadas por pequeños poblados lo que garantiza que el agua este contaminada. Tambien se ve río que aparenta tener densa vegetacion en sus márgenes.
