For polygons, this samples uniformly within the area of the polygon. For lines, this samples uniformly along the length of the linestring. For multi-part geometries, the weights of each part are selected according to their relevant attribute (area for Polygons, length for LineStrings), and then points are sampled from each part uniformly. Any other geometry type (e.g. Point, GeometryCollection) are ignored, and an empty MultiPoint geometry is returned. Parameters ---------- geom : any shapely.geometry.BaseGeometry type the shape that describes the area in which to sample. size : integer an integer denoting how many points to sample Returns ------- shapely.MultiPoint geometry containing the sampled points Examples -------- >>> from shapely.geometry import box >>> square = box(0,0,1,1) >>> uniform(square, size=102) # doctest: +SKIP )seed)size generatorzSampling is not supported for z geometry type.) stacklevel) numpyrandom default_rngis_emptyr geom_typer_uniform_polygonr _uniform_liner UserWarning)geomr rngr s J/var/www/html/immo/lib/python3.12/site-packages/geopandas/tools/_random.pyuniformrs@ ((c(2I |t}}| ~~++49EE ~~(T BB ((8H <cz|j|}t|j|djS)z/Sample points from an input shapely linestring.r T) normalized)rr interpolate union_all)rr r fracss rrrCs9   4  (E ((4(@ A K K MMrc|j\}}}}g}t||krqt|j||||j|||}||jj |d} |j | t||krq|j|t|d|jS)z>Sample uniformly from within a polygon using batched sampling.r)xycontains) predicateN) boundslenrrsindexqueryextendshuffler r!) rr r xminyminxmaxymax candidatesbatch valid_sampless rrrIs![[D$dJ j/D d6d6 ell000LM -( j/D j!
