NAME

       diffpos — compare the contents of two .3d files

SYNOPSIS

       diffpos .3d file .3d file  [threshold]

Description

       Diffpos  reports  stations which are in one file but not the other, and
       also stations which have moved  by  more  than  a  specified  threshold
       distance  in X, Y, or Z.  The threshold distance is given in metres and
       defaults to 0.01m if not specified.

       For backward compatibility  diffpos  will  also  read  the  .pos  files
       produced by earlier versions of cavern, or by 3dtopos.
