Hello All,

Hopefully someone can help me figure out this problem.  What I am trying to do is calculate the mean center for groups of 3D points.  Each point has a group that it is associated with, for example groups A, B, C.  I have 3 points for A: A1, A2, A3; 2 for B: B1, B2; and 1 for C: C1.  What I would like to do is calculate the average X, Y, Z values for each group and create a shapefile/feature class that contains these average points.  Therefore I would have one point for A, one for B, and one for C.  If anybody has any thoughts, I would greatly appreciate them.

Thanks,

Winn

You could try using the mean center tool (Spatial Statistics > Measuring Geographic Distribution > Mean Center)

Using the Case Field you can separate which points you want to calculate the mean center for.

This tool calculates the mean x, y, and z of your points.
