The ability to detect methane emissions using remote sensing depends on the available spectral bands of the sensor and often results in a lot of false positives. Vit Růžička et al. developed a semantic segmentation model for hyperspectral imagery and trained it on imagery from AVIRIS-NG. They developed a multispectral approach using ratios from bands that are available for WorldView-3 and a hyperspectral approach that uses a wider selection of bands. Each was used as input to a U-net. Their multispectral model out-performed other multispectral alternatives but was significantly poorer than their hyperspectral method. To evaluate the ability of their model to generalize to other satellites, they tested it on imagery from EMIT. While performance was lower than on in-domain images, it still performed reasonably well, even without any tuning. paper: https://lnkd.in/gwvdVgpy news: https://lnkd.in/gaMwD-ZC dataset: https://lnkd.in/gYgfddJg If you enjoy these posts and want to hear more, sign up my Computer Vision Insights newsletter: https://lnkd.in/g9bSuQDP #RemoteSensing #EarthObservation #ClimateAction #MachineLearning #DeepLearning #ComputerVision

the Landsat 8 and 9 satellites collect visual, near-, and shortwave-infrared images with the OLI (Operational Land Imager) and OLI-2 sensors, as well as thermal infrared (heat) data with the TIRS (Thermal Infrared Sensor) and TIRS-2, respectively. These instruments offer better spatial resolution than other commonly used satellite thermal sensors and can better distinguish glacial ice and ocean features such as ice fronts, rifts, sea ice leads, and polynyas. #Optics #SatelliteImaging #ThermalImaging

The remaining data and protostars from the eHOPS survey, which I had the privilege of leading, are now hosted by NASA. 🌌 You can dive into the catalog and our modeling results here: https://lnkd.in/gcMW8H8Q It's fascinating to see how the modeling techniques from this astronomical project are now playing a pivotal role in my current logistics projects. For instance, the predictive algorithms used for star formation are surprisingly effective in forecasting supply chain demands. As a little side note to my fellow astronomers: if you stumble upon any extraterrestrials circling those protostars, do let me know - some mysteries still keep me up at night! 😉✨ #AstronomyToLogistics #DataScience #SupplyChainInnovation #NASA #eHOPSProject

🌍 Addressing Geometric Challenges in Satellite Imaging for Land Monitoring 🛰 Satellite images often suffer from geometric errors that impair land monitoring and change detection analysis. These misalignments between consecutive acquisitions introduce noise and inaccuracies, particularly in high-temporal-resolution data collections such as Sentinel-2, Landsat, and PlanetScope. The article, written by Peresutti explores how to co-register a temporal stack of optical satellite images to mitigate these errors. Through extensive experiments, a workflow was developed that uses image-based co-registration to accurately align temporal images, thereby improving analysis accuracy. It was found that using an average temporal image as the template and a translation-only motion model produces the best results, significantly reducing the impact of geometric errors. These findings have been incorporated into the eo-learn library to facilitate use by other researchers and professionals. 🔗 More details and results are available in the blog: https://lnkd.in/dMfuqw3g #SatelliteImagery #GeometricErrors #LandMonitoring #ChangeDetection #MachineLearning #Sentinel2 #RemoteSensing #eoLearn #GIS #DataScience
