I've been doing a #DistanceLearning course on #RemoteSensing recently, just for fun. It's amazing how much high-quality Earth imagery is available for free!
I've been using #Landsat data to look at #deforestation in the #Amazon, here's my change map showing the loss of forest in a 150x150km region around the town of Apuí since 1984. It's definitely got worse in recent years... 😞
We are going through the bounty and diversity of this planet in full knowledge of our actions - we see it all happen from #Space.
But #RemoteSensing can also play a role in enforcement #ParisAgreement. A call to arms:
" EO science must undergo a radical overhaul: it must become more user-oriented, collaborative, and transdisciplinary; span the range from fiducial to contextual data; and embrace new technologies for data analysis (e.g., artificial intelligence)."
Some light aurorae visible across much of Canada tonight as seen from NOAA-20 AVHRR nighttime dynamic visible image taken 21 November around 0746 UTC. #RemoteSensing#aurora
Strong front across the South producing lightning in this image too. I don't think I've ever seen such an intense lightning strike that it burned out the pixels on a scan line for that long of a period! #RemoteSensing#weather
I am a curious and tenacious #researchanddevelopment scientist with specialties in multi-spectral #remotesensing, both #geospatial and #Astronomy -related. I spent the past 5 years inventing new and exciting ways to exploit high-resolution satellite imagery and 15 years before that as a research astrophysicist.
What's next? I would appreciate any leads for the next step in my career!
We just released data on crown maps for 100 million trees in the National Ecological Observatory Network (NEON) with information on location, species identify, size, and alive/dead status.
We created this dataset by combining deep learning, remote sensing, and extensive field data to build models that can detect and classify individual trees. Models are almost 80% accurate and can be improved with additional field data collection.
So why the pink? This WorldView satellite image from 11/05/23 tells the story: our wetland in Central Maui isn't wet. It tends to be driest right before the winter rains, but I haven't seen it this dry where there is hardly any water at all in this area.

"The Lunar Orbiter Laser Altimeter (LOLA) has collected and released almost 7 billion individual laser altimeter returns from the lunar surface. The LOLA data is used poleward of 79◦latitude as the elevation basemap necessary for calculating shading…”
