DESCRIPTION:mapchete EO extends mapchete with abstractions and utilities to
  read from Earth Observation (EO) archives\, with a primary focus on Senti
 nel-2 data. While mapchete provides a tile-based execution model for raste
 r and vector processing\, mapchete EO enables reading multidimensional arr
 ays (time series) from well known data archives.\n\nClass-based abstractio
 ns for handling Sentinel-2 products were engineered to also enable usage o
 utside of the mapchete context. They provide a unified interface to variou
 s data and metadata archives to automatically mask data using all availabl
 e metadata masks (SCL\, L1C\, etc.) as well as to apply BRDF correction wh
 ile reading the datza.\n\nThe second part of the talk focuses on operation
 al experience from processing Sentinel-2 data at global scale for the EOxC
 loudless product line. At this scale\, the system has to have multiple lay
 ers of fallbacks and retries in order to accomodate I/O related and tempor
 ary failures.\n\nAdditional challenges arise when processing data across t
 he antimeridian\, where data coverage is not consistent between various ar
 chives. These edge cases expose limitations that are not apparent in small
 er-scale workflows and require careful handling within global processing p
 ipelines.\n\nThe presentation will outline these challenges and discuss th
 eir implications for the design of robust\, large-scale Sentinel-2 process
 ing pipelines within an open source framework.
