#remote-sensing — Public Fediverse posts

I'm currently looking for a way to bring together my experience with #SmoothedParticleHydroynamics and #remoteSensing, and as part of this process I also wrote a converter (in #Julia, because this has to fit within some existing code which I wrote in that language) that allows me to export satellite imagery as #VTK unstructured grids, so that I can visualize them in #ParaView

It feels weird because ParaView *really* isn't suited for #GIS work, but in this case it turns out to be The Right Tool For The Job™.

Finally finished some light engineering for a bioacoustic monitoring job this summer, within the context of an agro-ecology grant. Test rig is currently running in the garden with the others in storage. Still missing some odd bits (U-bolts seem hard to source).

I'm very thankful to the astronauts on the International Space Station for taking a series of photos of Chennai, India for me.

They used the lens I requested, but the longest exposure time they used was ~0.07 s, when I really need them to take a much longer exposure time (like 1s second).

I can totally imagine what's happening when the astronaut sees my request... "One second? That doesn't make sense, the image would overexposed and blurry. That can't be what they meant, but I'll take some good images for them with shorter exposure times." 🙃

Rinse and repeat... Anyway, it's always helpful to get images like this, and 0.07 s is the longest they've taken for me yet, so we'll see if we can do something with it!

[Edit: Solved! Thanks @ai6yr, @headfirstonly, and @pmisson! I had thought the ISS was too far inland for it to be the coast.]

Dear Hive Mind: This photo shows two cities in India, but I don't know which they are. I would like to know out which they are so that I can figure out what all the bright dots in the image are. The original image (with much higher resolution) is here: https://eol.jsc.nasa.gov/SearchPhotos/photo.pl?mission=ISS074&roll=E&frame=88443

I am not sure which way is North, the image may be rotated. Are any of you familiar enough with Indian cities to work it out?

The #InternationalSpaceStation was over 18.9° N, 76.9° E when the photo was taken, but it is probably not taken directly downward.

WOW! An astronaut on the #InternationalSpaceStation captured a photo of the last rays of sun hitting a tall mountain in the #Himalayas

(I've adjusted the contrast to show more detail in the parts that aren't directly lit by the sun. Original here: https://eol.jsc.nasa.gov/SearchPhotos/photo.pl?mission=ISS074&roll=E&frame=88374)

☀️ Albedo vs. Surface Temperature: Why a "Bright" City Isn't Always Cooler

❗ Key findings from the current stage of research:
🔹 Vegetation (NDVI): Based on modeling results, biomass health accounted for approximately 40% of the variance in Calgary’s temperature regime in 2025.
🔹 Albedo (Reflectance): While it is commonly assumed that high surface reflectance reduces heat absorption, satellite data (broadband shortwave albedo) reveals a far more nuanced picture.

🔥 The Seton Anomaly
The scatter plot clearly shows a wide distribution of values. The community of Seton is a particularly striking example: despite its high average albedo (likely due to light-colored soils at construction sites and new roofing materials), the area remains in a "heat zone" (classified as Warm Background in my model).

❗ Albedo plays a role, but it is not the dominant factor in Calgary’s environment.

China launched a Pakistani satellite from the Taiyuan Satellite Launch Center in north China's Shanxi Province on Saturday.

The satellite, named PRSC-EO3, was lifted off at 8:15 p.m. (Beijing Time) by a Long March-6 carrier rocket and successfully entered its planned orbit.

🌿 Can trees cool #Calgary ? Summer 2025 data from 193 neighborhoods reveals a tipping point: 0.34 NDVI.
🔹 Below 0.34: Isolated trees in "concrete jungles" provide ~0 cooling ROI.
🔹 Above 0.34: Cooling "clicks in" & efficiency jumps.
Stats: Vegetation explains 40% of heat; 60% is locked in asphalt & design. Where we can't plant, we must use high-albedo materials.
