Random points from mask raster layer

This algorithm creates a new point layer with a given number of random points, all of them in the area where the given mask evaluates to true.

Parameters

Mask raster layer [raster]

A mask raster layer to draw locations from.

Number of points [number]

Number of points to be drawn.

Minimum distance between points (in meters) [number]

A minimum distance between points can be specified. A point will not be added if there is an already generated point within this (Euclidean) distance from the generated location.

Default: 0

Random seed [number]

The seed for the random generator can be provided.

Outputs

Output point layer [vectorDestination]

Vector file destination.
