Cluster Depth Solutions

Use the Pdepth > Cluster Solutions option (CLUSTER GX) to "cluster" depth solutions from the current database into additional merged solutions. The clustered solutions are appended to the end of each selected line in the current database. The user assigns the new flag value for the clustered solutions. Existing solutions with the new flag value are deleted before the new clusters are generated.

Cluster Depth Solutions dialog options

Input solution depth channel	The channel containing the solution depths to be clustered.
Output solution depth channel	The channel to write the clustered solutions depths into. This may be the same as the input solution depth channel.
Input flag (0-1)	Selects the type of depth solutions to be clustered (i.e., enter "0" to cluster dike solutions or "1" to cluster contact solutions).
Output flag (2-9)	Selects the flag value for the solutions output from the CLUSTER GX. You may use any integer value except "0" or "1".
Minimum # of solutions (2)	Minimum number of solutions required in a cluster to be saved. Any clusters with fewer solutions will be skipped.
Window half-width in X (5)	This parameter sets the horizontal dimension of the rectangular window used for clustering. It can be specified either as an absolute distance or as a percent of depth. The window type is set below. (The value must be greater than 0).
Window half-height in Z (5)	This parameter sets the vertical dimension of the rectangular window used for clustering. It can be specified either as an absolute distance or as a percent of depth. The window type is set below. (The value must be greater than 0).
Window type	Determines whether window dimensions above are absolute distance units or percent of depth.

Application Notes

The number of solutions in each cluster is saved in the "Lag" channel. Note that previous runs with the same output flag will be deleted before the new clusters are computed. Assigning different output flag values can save more than one cluster run.

Note that you can work with any distance units (e.g., meters, kilometers, feet) as long as you are consistent. The X, Y, Distance, and depth channels need to be in the same units.

The " Input solution depth channel" needs to be specified, because there are two choices: "Depth_sl" (the depth referenced to sea level) and "Z_both" (the depth relative to the flight elevation). If you plan to export the solutions to GM‑SYS, we suggest that you use "Depth_sl".
