Context
The building filter is hardcoded to BDTOPO (French national building dataset). This makes the pipeline unusable outside France without modifying core code.
Goal
Abstract the building filter behind a common interface that accepts any polygon layer — BDTOPO, OpenStreetMap, Microsoft Building Footprints, or a user-supplied shapefile. The BDTOPO implementation becomes the default.
Relevant files
pipeline/aggregation.py — building filter logicconfig.yml — source_topo_dir currently points to BDTOPO
Out of scope
No new footprint sources need to be bundled — the interface + BDTOPO adapter is the deliverable.
Expected difficulty
Medium — requires understanding how the spatial join works between detected polygons and building footprints.
