healpix_geo.auto.zone_coverage#

healpix_geo.auto.zone_coverage(bbox, grid, *, flat=True)#

Search the cells covering the given bounding box

Parameters:

  • bbox (tuple of float) – The 2D bounding box to rasterize.

  • grid (Grid) – The definition of the HEALPix grid.

  • flat (bool, default: True) – If True, the cells returned will all be at the passed depth.

Returns:

  • cell_ids (numpy.ndarray) – The rasterized cell ids.

  • levels (numpy.ndarray) – The refinement levels of the cell ids. If flat is True, these will all have the same value. Only returned for nested and ring.

  • fully_covered (numpy.ndarray) – Boolean array marking whether the cells are fully covered by the bounding box.
