Returns the distance between a polygon and point.

Parameters:¶

poly : libpysal.cg.Polygon¶

A polygon to compute distance from.

pt : libpysal.cg.Point¶

a point to compute distance from

Returns:¶

dist – The distance between poly and point.

Return type:¶

float

Examples

>>> poly = Polygon([Point((0, 0)), Point((1, 0)), Point((1, 1)), Point((0, 1))])
>>> pt = Point((2, 0.5))
>>> get_polygon_point_dist(poly, pt)
1.0

>>> pt2 = Point((0.5, 0.5))
>>> get_polygon_point_dist(poly, pt2)
0.0
