DESCRIPTION:Over the past years\, mapchete has evolved from a tile-based ra
 ster and vector processing library into a modular ecosystem for building a
 nd operating large-scale geospatial data processing pipelines. Previous pr
 esentations at FOSS4G focused on the core package and touching scalable pr
 ocessing patterns using dask and mapchete.\n\nThis talk presents the next 
 step: the open source publication of additional components developed in a 
 production context\, including mapchete EO\, mapchete Hub\, and mapchete H
 ub CLI. These packages extend mapchete's core processing model towards Ear
 th Observation (EO) use cases and distributed execution\, with a focus on 
 reproducibility\, scalability\, and a variety of (pre)processesing capabil
 ities relevant for EO.\n\nmapchete EO provides higher-level primitives for
  working with satellite imagery (primarily Sentinel-2)\, including typical
  preprocessing steps such as cloud masking\, BRDF correction\, and tempora
 l compositing. These components are derived from operational pipelines use
 d in the EOxCloudles (cloudless.eox.at) product line\, where consistent la
 rge-scale processing and data quality constraints are critical.\n\nmapchet
 e Hub introduces a service layer for orchestrating distributed processing 
 of mapchete tasks. Processing jobs can be submitted\, scheduled\, and moni
 tored via an API. The API design is oriented towards the OGC API - Process
 es standard\, aligning mapchete-based workflows with emerging interoperabl
 e interfaces in the geospatial ecosystem. The accompanying CLI (mapchete h
 ub CLI) provides a minimal interface for interacting with this system with
 out requiring custom integration.\n\nIn addition to the software component
 s\, the talk covers recent changes in packaging and distribution. All pack
 ages are now published via both PyPI and Conda\, and container images are 
 provided through GitHub Container Registry. All packages were moved to a d
 edicated mapchete organization.
