DIFFPOS(1)

NAME
diffpos - compare two processed data files

SYNOPSIS
diffpos FILE1 FILE2 [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. THRESHOLD is a distance in metres and defaults to 0.01m if not specified.

Note that the input files can be any format the "img" library can read (and can be different formats), so it works with Survex .3d and .pos files, Compass .plt and .plf files, CMAP .sht, .adj and .una files.
