pprepair(1) 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
