geopandas.GeoSeries.affine_transform#

GeoSeries.affine_transform(matrix)[source]#

Return a GeoSeries with translated geometries.

See http://shapely.readthedocs.io/en/stable/manual.html#shapely.affinity.affine_transform for details.

Parameters:

matrix: List or tuple

6 or 12 items for 2D or 3D transformations respectively.

For 2D affine transformations, the 6 parameter matrix is [a, b, d, e, xoff, yoff]

For 3D affine transformations, the 12 parameter matrix is [a, b, c, d, e, f, g, h, i, xoff, yoff, zoff]

Examples

>>> from shapely.geometry import Point, LineString, Polygon
>>> s = geopandas.GeoSeries(
...     [
...         Point(1, 1),
...         LineString([(1, -1), (1, 0)]),
...         Polygon([(3, -1), (4, 0), (3, 1)]),
...     ]
... )
>>> s
0                         POINT (1 1)
1              LINESTRING (1 -1, 1 0)
2    POLYGON ((3 -1, 4 0, 3 1, 3 -1))
dtype: geometry

>>> s.affine_transform([2, 3, 2, 4, 5, 2])
0                          POINT (10 8)
1                 LINESTRING (4 0, 7 4)
2    POLYGON ((8 4, 13 10, 14 12, 8 4))
