Create Random Points

This node generates random points from a uniform distribution within (or along) each input geometry. For polygons, the points will be sampled within the area of the polygon. For lines, they will be sampled 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. Any other geometry type (e.g., Point, MultiPoint, GeometryCollection) is ignored, and an empty MultiPoint geometry is returned.

The numerical value column is used to determine the number of points to be generated for the geometry of the same row. Additionally, you need to provide an ID column that will be used to identify the original input row.

The node will create a new MultiPoint geometry that includes the random set of points for each input geometry, which can be exploded into individual points using the Multipart To Singlepart node.

The node is based on the GeoPandas project and uses the following related information and functions:
