# DBSCAN(Density Clustering)

>  Density Clustering (DBSCAN) groups together points that are closely packed in space and marks points in low-density regions as outliers. It does not require the number of clusters to be specified in advance.

The algorithm discovers clusters automatically and labels isolated points as noise. 

<Note>
  * DBSCAN is the only clustering algorithm in this package that can automatically **detect outliers** and determine the number of clusters on its own.
  * NeighborhoodDistance, Estimated potential neighbor distance
  * MinNeighbors, Estimated potential neighbor count but if there is no estimation, it can be estimated automatically with "Auto" option.
</Note>

### Use Cases

* **Noise detection**: Identify irregular or outlier geometries in a set of building elements.
* **Unknown number of clusters**: When you do not know how many groups exist in your spatial data.
