This effect is also visible on the Sentinel-3 OLCI Level1B input data: it is the consequence of differences in ground sampling distance between PROBA-V (100m at nadir) and Sentinel-3/OLCI (300m at nadir). However, the NDVI V2 shows clearly less sharpness and spatial detail compared to NDVI V1. The Collection 300m NDVI V2, derived from Sentinel-3 OLCI observations, displays a good consistency with Collection 300m NDVI Version 1 derived from PROBA-V observations, as shown on the maps below. Furthermore, the comparison with other EO-derived NDVI products must be considered carefully since the NDVI is, by definition, sensor-dependent. At the opposite, since the NDVI is a mathematical index, the accuracy assessment comparing with ground measurements is not relevant. Therefore, the product completeness, the spatial, temporal and statistical consistencies are assessed. The validation procedure of NDVI follows as much as possible the CEOS LPV guidelines defined for the validation of LAI.

Constraints applied on viewing and solar zenith angles in the MVC, which is not the case for the version 2 of NDVI 1km.

Pixels wrongly identified as 'land' in the S10 NDVI status map are re-classified as 'sea' (value 254).

Re-scaling to include the quality information (status map) in the main NDVI layer.

Standard 10-day synthesis (S10) from the PROBA-V programme: they are already cloud screened, atmospherically-corrected Maximum Value Composites (MVC) over a 10 day period.

BRDF normalization to correct for differences in Sun-sensor geometry,.

The number of observations is calculated as the minimum of the number of observations used for BRDF correction over the 7 TOC reflectance bands.

Uncertainty is calculated by error propagation of the uncertainty of the seven input top-of-canopy (TOC) reflectances.

The four narrow Red and three narrow NIR are averaged into a broad Red and NIR band, that are then used to calculate the NDVI.

Then 10-daily BRDF normalized reflectances are computed from 30 days of input reflectances.

Reflectances from Sentinel-3/OLCI, in seven Red and Near-infrared (NIR) bands are first atmospherically corrected.

For now, grab the March Android update and enjoy being a Pixel phone owner. Many of these are updates that will come to apps, so the availability here could be slowish to rollout. OK, then.Īlright, so that’s it for the Pixel Feature Drop. Of course, you’ll have to own a phone with Pixel Stand support in order to see this stuff, like the Pixel 3, Pixel 4, and Pixel 5.įinally, Google worked with Kraken Sports to create a special underwater case for Pixel phones to be able to take better underwater pictures – it costs $325. In the sleeping department, Google is adding a “new, updated bedtime screen, along with redesigned notifications” when you use your Pixel Stand. Be on the lookout for those come March 8. It sounds like the list includes Google Messages, Hangouts and Chat, WhatsApp, Facebook Messenger, Verizon Messages, Telegram, and Slack.įor new wallpapers, to celebrate International Women’s Day on March 8, Google is bringing a set of wallpapers (above) that should be available in the Wallpapers app on your Pixel phone. Starting today, Google says “select messaging apps” now have access to Smart Compose. With Smart Compose, Google has given the keyboard smarts that allow it to complete your sentences like magic, but the functionality has been pretty limited. At that web portal ( ), you’ll find recordings and transcripts and search capabilities within. Pixel owners have had access to the ultra-smart and handy Google Recorder app for some time, but for this month, Google has added the ability to share links with others to your audio files and has launched a web portal for accessing your own recordings. Today, Google sent out another drop, so if you own a Pixel phone, you have new goodies to play with.įor the March 2021 Pixel Feature Drop, Google is improving the Recorder app, bringing Smart Compose to more apps, giving you new wallpapers, helping you get more ZZZs, and has a way for you to capture underwater photos.

As a part of the benefit to owning a Google Pixel phone, you not only get regularly scheduled updates, you also get new batches of software features through the Pixel Feature Drop program.
