regionmask._OneRegion

class regionmask._OneRegion(number, name, abbrev, outline)

a single Region, used as member of Regions

Parameters:

• number (int) – Number of this region.

• name (string) – Long name of this region.

• abbrev (string) – Abbreviation of this region.

• outline (Nx2 array of vertices, Polygon or MultiPolygon) – Coordinates/ outline of the region as shapely Polygon/ MultiPolygon or list.

Examples

_OneRegion can be created with numpy-style outlines:

>>> outl = ((0, 0), (0, 1), (1, 1.), (1, 0))
>>> r = _OneRegion(1, 'Unit Square', 'USq', outl)
>>> r
<regionmask._OneRegion: Unit Square (USq / 1)>

or by passing shapely Polygons:

>>> from shapely.geometry import Polygon
>>> poly = Polygon(outl)
>>> r = _OneRegion(1, 'Unit Square', 'USq', poly)
>>> r
<regionmask._OneRegion: Unit Square (USq / 1)>

__init__(number, name, abbrev, outline)
