NAME

pprepair - planar partition repair tool

SYNOPSIS

pprepair [ [-i filename [schemaindex]] [-o filename] [-fix] [-d] | -p [-i filename [
schemaindex]] [-t] [-otnt filename] [-vh] [-sr ratio] [-v] [-au] [-rtnn] [-rtam]
[-rtlb] [-rrlb] [-rrrn] [-rpl filename] [-rem filename] [-ot filename] [-otwp
filename] [-bd] [-rp] [-owp] [-o filename] [-pi] ]

DESCRIPTION

pprepair (planar partition repair) takes a set of polygons and ensures that they form a
valid planar partition, made of valid polygons and having no gaps or overlaps. It can be
used as a validator, telling of problems in individual polygons or in the planar
partition, and also as an automatic repair tool, outputting a set of polygons that do form
a valid planar partition.

OPTIONS

Basic options

-i filename
Add this file to the triangulation using this schema index

-o filename
Output the reconstructed polygons in this file

-fix Automagically repair (same as -rrlb -rrrn)

-d Dissolve the boundaries between regions with the same tag according to the schema
index

Possible steps (in usual processing order)

-i filename
Add this file to the triangulation using this schema index

-t Tag the triangulation

-otnt filename
Output the tagged triangulation with the number of tags to this file

-vh Consider holes as valid

-sr ration
Split invalid regions at triangles with a higher aspect ratio than this

-v Validate

-au Allow removing invalid regions (where convenient)

-rtnn Repair triangles by assigning them to the neighbour present on most sides

-rtam Repair triangles by assigning them to a neighbour present on at least 2 sides

-rtlb Repair triangles by assigning them to the neighbour present along the longest part
of their boundary

-rrlb Repair regions by assigning them to the neighbour present along the longest part of
their boundary

-rrrn Repair regions by assigning them to a random neighbour

-rpl filename
Repair by assigning according to the priority list in this file

-rem filename
Repair for edge matching according to the priority list in this file

-ot filename
Output the triangulation to this file

-otwp filename
Output the triangulation to this file, including the input file where each triangle
came from

-bd Removes unnecessary vertices before reconstruction to support larger data sets (try
if you get a segmentation fault)

-rp Reconstruct polygons

-o filename
Output the reconstructed polygons in this file

-owp filename
Output the reconstructed polygons in this file, including the input file where they
came from

-pi Print triangulation information

EXAMPLE

pprepair -i "myInput.shp" -o "myOutput.shp" -fix
