geopandas.GeoSeries.scale¶

GeoSeries.scale(xfact=1.0, yfact=1.0, zfact=1.0, origin='center')¶

Returns a GeoSeries with scaled geometries.

The geometries can be scaled by different factors along each dimension. Negative scale factors will mirror or reflect coordinates.

See http://shapely.readthedocs.io/en/latest/manual.html#shapely.affinity.scale for details.

Parameters

xfact, yfact, zfactfloat, float, float: Scaling factors for the x, y, and z dimensions respectively.
originstring, Point, or tuple: The point of origin can be a keyword ‘center’ for the 2D bounding box center (default), ‘centroid’ for the geometry’s 2D centroid, a Point object or a coordinate tuple (x, y, z).
