Random points from categorized raster layer¶
This algorithm creates a new point layer with a given number of random points, all of them within the categories of the given categorized raster layer.
Parameters
- Categorized raster layer [raster]
- A categorized raster layer to draw points from.
- Number of points per category [string]
- Number of points to draw from each category. Set a single value N to draw N points for each category. Set a list of values N1, N2, … Ni, … to draw Ni points for category i.
- Minimum distance between points (in meters) [number]
A minimum (Euclidean) distance between points can be specified.
Default: 0
- Minimum distance between points inside category (in meters) [number]
A minimum (Euclidean) distance between points in a category can be specified.
Default: 0
- Random seed [number]
- The seed for the random generator can be provided.
Outputs
- Output point layer [vectorDestination]
- Vector file destination.
