  • clisops version: 0.9.6
  • Python version: 3.10
  • Operating System: ubuntu

Description

When using clisops.core.average_shape, I'm getting GEOSException: TopologyException: unable to assign free hole to a shell with a multipolygon. This error is raised by shape_bbox_indexer unary_union operation.

The logic in shape_bbox_indexer is only meant to make a rough subset of the area of interest to reduce data transfers. We can probably compute a simple convex hull to get the rough shape of the bounding box.
