@DrKJoyce @spatialthoughts I recently saw a post on the GEE developers group were others also mentioned the same server performance issues from Nov 13. Perhaps check there to see any updates (assuming this is a related issue).

@calebrob6 @hannah_kerner @jacobsn @opencholmes @GhoshPrivate @Adeal_GIS @matthmohr @rdodhia @BDataScientist Great work! Is it possible to download data just for a single country and only the binary labels?

[Hannah Kerner @hannah_kerner]

Fields of The World is an open-source project (links below). We hope to grow the dataset in the future with community contributions.

@Nrg8000 @SatelliteSci The where masking option that you use produces missing pixels whereas the updateMask option does not. It seems to me that the updateMask option is the correct approach here. https://t.co/Au55JVqQP9

The Sentinel-2C satellite that should be launched tonight is expected to replace the Sentinel-2A satellite, which is, as far as I know, a perfectly healthy mission that is still performing well more than 9 years after launch. However, why should a successful launch of Sentinel-2C lead to the decommissioning of a functioning Sentinel-2A satellite?

If S-2A is not shut down, it would mean that for the first time ever, we will have three Sentinel satellites in orbit, which should significantly increase the revisit time of the Sentinel constellation (currently once every five days to twice every five days). This has benefits across applications such as land cover classification, crop yield forecasting, disaster management, and several other use cases with societal, economic, and environmental impacts.

Are these benefits not worth the few million euros per year required to keep Sentinel-2A operational for as long as possible? Or are there other reasons besides cost that I am overlooking?

[Geethen @Geethen1]

@sherwang Thanks for the heads up :).

Since the oloffson method and PPI produce similar results for area estimation, when (in practice) would you suggest using one approach over the other?

Our paper "Regression Trees for Fast and Adaptive Prediction Intervals," co-authored with @kuben45, @mpotto1 and @rbstern, is now published in Information Sciences! 🎉

We introduce Locart and Loforest to calibrate prediction intervals for regression with coverage guarantees. +

My take on the 'Anatomy of a Matplotlib Figure' for geospatial visualization. Check out the notebook that creates the plot using #matplotlib using fancyarrowpatch annotations. Feel free to use/adapt for your own teaching! https://t.co/lfCqx8svMo
