Hi TP Mann,
I am not sure exactly what you mean by: "calculate the mean, max. and min. distances to other features "
There are various tools available to you to calculate distances between features in ArcMap.
Take a look at the following options:
1. Spatial Statistics Tools -> Measuring Geographic Distances -> Central Feature (or Mean Center) on your set of points.
2. Analysis Tools -> Proximity -> Point Distance tool to get the distances.
3. (Hawth's Analysis Tools for ArcGIS) http://www.spatialec...pntdistbetw.php
For ArcGIS related questions, I would recommend you post your problem or search for answers on the ESRI support forums:http://support.esri....=forums.gateway
as these forums deals specifically with ArcGIS 'how to" problems.
Hope this helps,
