  * **Proximity Distance**: The proximity distance to cluster points together.

  * **Cluster PTS Min**: The minimum amount of points to start a cluster.

  * **Initial Match Percent Min**: The minimal initial match percentage when looking for a candidate detection.

  * **Match Percent Min**: The minimal match percentage for a template detection.

  * **Neighboorhood Dist**: The Neighboorhood distance.

  * **Fine Neighboorhood Dist**: The distance around a projection to compare points in and out.

  * **Sign Pts Min**: The minimum number of points for a feature.

  * **Ground Cell Size**: The size for a ground cell, used to identify ground height.

  * **Ground Margin**: The margin to get points above lowest coordinate within ground cell.

  * **XY Step Size**: The step size to reposition the projection.

  * **Angle Step Size**: The step size to rotate the projection
