Przed chwilą wraz z sześciorgiem uczniów otrzymałem informację, że nasze zdjęcia, zgłoszone na konkurs „Uchwyć piękno naszej planety”, wraz z czterdziestoma siedmioma innymi zostały zakwalifikowane do etapu głosowania. Od dzisiaj aż do 11 listopada do godziny 12:00 naszego czasu można będzie oddać głos na wskazane zdjęcia – do trzech najwyżej. Technicznie polega to na umieszczeniu kropki na wskazanych miniaturach, z tym, że jedno zdjęcie można obdarzyć tylko jednym głosem. Ogłoszenie wyników nastąpi we środę, 19 listopada w postaci komunikatu na stronie konkursu.
A oto zdjęcia, wykonane przez nas w ramach zajęć astronomicznych dla zaawansowanych, jakie prowadzę we środy i czwartki wieczorami. Kolejność jak na stronie konkursu.
Dawid – La Rinconada
La Rinconada, located in Peru, is the highest city above sea level in the world. Due to its geographical location, the city has very limited development opportunities. It is bordered by the Cordillera Apolobamba mountain range to the north and west, a lake to the east, and what appear to be post-mining areas to the south. The photo was taken by Sentinal 2 on 22 September 2025.
Nikodem – Vistula River in Warsaw
I have chosen this place becuse it shows the critical level of the river that passes through Warsaw. The Satellite was a Sentinel 2 , detector L1C, band NDSI. The date is 2025-09-12.
Amelia – Allahabad
It’s a large city with a population of about one million. Its problem is water shortage. The city is surrounded by two rivers: the Ganges and the Yamuna. The Ganges River is heavily polluted. This image was taken by a satelite Sentinel-2, L1C, band „false color”
GS- New Orleans
New Orleans, US, satellite Sentinel 2_L2A, SWIR band, photo date 2025-05-31. The city of New Orleans is located along the Mississippi River and is trapped between the swamps and lakes. Twenty years ago it was almost destroyed by Hurricane Katrina.
Kamil- Rijad
The image shows the city of Riyadh in the middle of the Ad-Dahna Desert in Saudi Arabia. I chose this location because it shows the difference between the desert sands and the city. Orange shades indicate the desert areas, while brown shades indicate urban development. The image also clearly shows the street grid. The image was taken in the NDSI layer on October 23, 2025, by the Sentinel-2 satellite with its L2A array.
Maciej – Longeyarbyen
Longyearbyen, the fastest-warming town on Earth, a once completely snow-covered town, is now getting warmer and warmer every day, melting the snow and ice surrounding the place because of climate change. You can clearly see Longyearbyen’s airport in the center of the image and Longyearbyen itself right next to it. The image is shown in the false color composition, the red color represents plant-covered land. Image taken by Sentinel 2, 2024-06-29.
Lilianna – Norylsk
The image depicts the city of Norilsk, located in northern Siberia, Russia. The image was done in False Color (urban) composite layer based on bands B12, B12, B4. I have chosen this area because it shows a struggle between urbanised city and harsh nature surrounding it. Specifically, the city is located in the Arctic tundra, which can be seen on the image – dark blue color may represent snow or ice and is present within the image. The city of Norilsk is clearly in a conflict with nature, as heavy industry plays a major role there, which negatively affects the environment. Therefore, no vegetation can be seen around the city on the image (green color). On the other hand the city is in a partial symbiosis with nature, because despite harsh conditions the area is rich in mineral resources, which is a reason why it was founded. The image comes from satellite Sentinel-2 L2A and I accessed it using Copernicus Browser. The image was captured on 10th October 2025.
Zachęcam do głosowania na wybrane zdjęcia, no i do zainteresowania problematyką satelitarnych obrazowań Ziemi.
