locan.data.regions.region_utils.surrounding_region(region, distance=100, support=None, **kwargs)[source]¶

Define surrounding region by extending a region and returning the extended region excluding the input region. If region contains a list of regions, the unification of all extended regions is returned.

Parameters:

region (Region) – Original region(s)
distance (int | float) – Distance by which the region is extended orthogonal to its boundary.
support (Region | None) – A region defining the maximum outer boundary.
kwargs (Any) – Other parameters passed to shapely.geometry.buffer() for Region2D objects.

Return type:

Region
