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, by 3dtopos, or by aven's export feature (requires 1.2.19 or later).
