Description

Example job j-25022615155945a2a14cfbc36d4e5467

Loading mask in UTM and target cube in epsg:3035 causes target cube to have a layoutDefinition that is not nicely aligned with the target extent provided by filter_bbox.

The global extent does not necessarily need to be global across all cubes, it mostly makes sense for cubes that can have a shared layoutdefinition, so share a CRS.

Research direction

Start with example job j-25022615155945a2a14cfbc36d4e5467 and trace how global_extent, filter_bbox, layoutDefinition, and CRS are handled when cubes use UTM and EPSG:3035. Compare the resulting alignment for cubes sharing a CRS versus cubes with different CRSs. Done means the target cube remains correctly aligned when these mixed-CRS inputs are processed.
