Nouveaux services d'images Landsat Collection 2

EmilyWindahl

Au printemps 2021, Esri introduira de nouveaux services d'images Landsat composés des images Landsat 8, Collection 2 Niveau-2 publiées par l'USGS en décembre 2020. Ces nouveaux services incluront non seulement toutes les améliorations de qualité de la Collection 2, mais fourniront également aux utilisateurs des images corrigées atmosphériquement et prêtes pour l'analyse avec la mise à niveau supplémentaire des produits du Niveau-1 au Niveau-2.<\/P>

Le plan initial était de retirer les services existants, mais il s'avère que nous <\/SPAN>ne <\/SPAN>retirerons pas les services existants, finalement. Nous continuerons à prendre en charge et à mettre à jour tous les services d'images Landsat Niveau-1 existants en plus de publier le nouveau service Niveau-2.<\/SPAN><\/P>Pour plus de détails, consultez Présentation de Landsat Collection 2.<\/P>

Thank you for the clarification @RWaterman. So is my revised understanding correct: it is not possible to narrow to a specific pre-Landsat 8 year, say 1987, using existing ArcGIS Online services?

Background: we have staff who are using Google Earth Engine to extract specific historical years from Landsat going back to 1984 for analysis in ArcGIS Desktop. It's created an administrative storage and management problem in the filesystem as people cache their own idiosyncratic copies. I'm looking at options alleviate this overhead.

@MattWilkie1 , we will have the new Collection 2 service available very soon to provide as much overlap and transition time as we possibly can.

We will post details in the blog post Emily noted as soon as the new service is available: Introducing Landsat Collection 2 and retiring Collection 1.

The new service is just Landsat 8 Collection 2 (as replacement for the existing Landsat 8 Collection 1).

It doesn't like there is to be any service availability overlap between Collection 1 retiring and Collection 2 being brought online. Is that right? We're only a few weeks away from C1 going away and I haven't found any C2 availability. How are we to prep for the change? What do we do with new projects being created now that seek to use these services? Is historical landsat 4&5 going to be in the C2 service or is just LS8? (At only every 5 years the GLS service is temporally coarser grained than what we're looking for.)

Thanks!
