NAME

v.rmdup - Remove duplicate items GRASS vector file. (GRASS Vector Program)

SYNOPSIS

v.rmdup
v.rmdup help
v.rmdup input=name output=name [threshold=value]

DESCRIPTION

v.rmdup removes duplicate lines, areas, and points from a binary vector file (input). Duplicate may be defined as exact (less than 1.12e-16 for IEEE double precision), or defined with a threshold.

Parameters:

input=name
Name of a binary vector file
output=name
Name given to binary vector output file.
threshold=value
Threshold for defining duplicate lines, areas, and points.
The search technique used by v.rmdup is not extremely sophisticated and may take a long time for large files. Instead, only two sets of lines, areas, or points are active at any one time (so it is conservative with memory).
