@ohagolle - After three successive summer droughts in 2018, 2019, and 2020, the dieback of oaks has considerably increased in France.

Florian Mouret et al from #CESBIO and #Orleans University, have set-up a new method to monitor oak dieback, using #Sentinel2 #EarthObservation data as input, with terrain measurements to train the classification model. uses the #Iota2 opensource framework to process large multi-temporal #timesSries

After three successive summer droughts in 2018, 2019, and 2020, the dieback of oaks has considerably increased in the center of France.

Florian Mouret and his colleagues from #CESBIO and #Orleans University, have set-up a new method to monitor oak dieback, using #Sentinel2 #EarthObservation data as input, with terrain measurements to train the classification model.

The method uses the #Iota2 opensource framework to process large multi-temporal #timesSeries

At #CESBIO laboratory, we promote a new very high resolution mission, #SentinelHR, to complement #Sentinel2 with 2 m resolution images acquired with a systematic and global revisit every 10 to 30 days and 4 spectral bands.

We are ready to trade revisit for resolution, as we feel that landscape details with high frequency (buildings, trees, hedges, roads) tend to change less than the low frequency details. But demonstrating it needed work.

We made two studies to try to prove it.

Great article on the #CESBIO #Multitemp blog by @inglada on the production of a land cover map of Sahel with #iota2 . The methodology is very inspiring. I look forward to learning more about the generation of pseudo-climatic maps from WorldClim data. #EarthObservation #RemoteSensing #GISchat

The #Multitemp blog (Séries Temporelles in French) is just 10 years old ! It was started to provide information and news around the SPOT4 (Take5) experiment in preparation to #Sentinel2. And as we had fun writing the posts, we went on, with my co-editor from #CESBIO , Simon Gascoin ( @[email protected] )

More than 850 000 pages have been read so far, on our almost 1000 posts !

Claire Pascal successfully defended her PhD one month ago at #CESBIO. She studied how the current and future #satellites allow to monitor the hydrological cycle at the scale of a large Indian region: #Telangana
