EO, RS, GS, DS, AI, ML, DL, BS, WTF? Everybody in the Geosciences (GS) and Remote Sensing (RS) community is now aware of the great advances in Data Science (DS) and Machine Learning (ML) that have taken place in the last 10 years. Although many people talk about Deep Learning (DL) or Artificial Intelligence (AI), […]
The Indus basin has one of the largest irrigation system in the world. Available water resources are abstracted almost entirely, mostly for crop irrigation in Pakistan. The Indus basin is also considered as one of the large basins in Asia with the highest dependence on snowmelt runoff. The contribution of snow and ice melt to […]
=> Les techniques de l’état de l’art en Deep Learning permettent-elles une délinéation individuelle de chaque parcelle de culture, comme le laisse penser cet article récent ? C’est ce que nous avons cherché à savoir au cours d’un stage au CESBIO en cherchant à qualifier l’architecture Mask R-CNN pour cette tâche. Nous vous livrons ici […]
=> Do state-of-the-art deep learning techniques allow for individual delineation of each cropland, as suggested by this recent article? In the context of an internship at CESBIO, we tried to evaluate the performance of Mask R-CNN architecture for this task. In this post, we summarize what we learned. Mask R-CNN principles To sum up, Mask […]
A few years only after its worst drought in 1,200 years (2011-2016), the drought returns to California. Lake Oroville is both a witness and a victim of the extreme hydro-meteorological variability in the Golden State. It provides water to « homes, farms, and industries in the San Francisco Bay area, the San Joaquin Valley and Southern […]
Malgré des chutes de neige tardives en mai, la durée d’enneigement est déficitaire dans les Pyrénées cette année comme on peut le voir sur cette synthèse d’images satellitaires: On se souvient aussi de la tempête Filomena qui a blanchi le piedmont pyrénéen le 10 janvier, bien visible sur le graphique ci-dessous. Suivant une suggestion de […]
Trois mois après le dépôt de poussières sahariennes qui avait coloré le manteau neigeux en orange, et grâce à la participation de nombreux citoyens-scientifiques, nous sommes en mesure d’annoncer que la masse de poussière tombée dans les Alpes et les Pyrénées varie entre 0.2 et 30 grammes par mètre carré ce qui représente des centaines […]
Muldrow Glacier (McKinley Glacier) is a large glacier in Denali National Park and Preserve in Alaska, USA. It is now moving 100 times faster than normal, which means that it is undergoing a « surge ». The abrupt acceleration of the glacier movement is clearly visible in the recent series of Sentinel-1 SAR backscatter images (animation below). […]
=> Do we need to remind you of all the collateral damage linked to deforestation or the eco-system services that forests provide ? We have already talked about these in this blog (here and there too). Yet forests are disappearing at an alarming rate. Between 1990 and 2020, an area of forest equal to more […]
