# Terrain Processor: Area: Local Minimum Cluster

#### Task details

**Task name** : Area: Local Minimum Cluster

**Dll plugin name** : BITasksPlugin.dll

**Geometry type** : Polygon, PolygonM, PolygonZ

**Heightmap** : Yes

#### Description

Random placement of multiple objects into local depressions within the extent of the polygons. It creates linear clusters.

#### Task parameters

- **Random seed** - number used to initialize pseudorandom number generator.

#### Object prototype parameters

- **OBJECT** - Object's prototype name
- **MINHEIGHT** - Minimal size in %
- **MAXHEIGHT** - Maximal size in %
- **MINDIST** - Minimal distance in meters
- **GROUPID** - Cluster group id.
- **MINCOUNT** - Minimal instances count.
- **MAXCOUNT** - Maximal instances count.
- **MINRADIUS** - Minimal occurence radius.
- **MAXRADIUS** - Maxima occurence radius.

#### Usage

Use it for placing objects in local depressions, e.g. wetland tree or bush clusters.

#### Algorithm

1. Find local maximals.
1. Populate linear cluster as usual.
