State plane and UTM are NOT projections, they are co-ordinate systems. Each (and each state) have an associated projection. Thus the associated projection for the UTM co-ordinate referencing system is one of many transverse mercator projections (zone such-and-such) unless of course it is in the far north or south. We use a conic state plane projection here in Montana because of the east-west orientation of the state. Steven ....... Steven R Holloway [log in to unmask] --- End Forwarded Message ---
