PROGRAM:
NAME
prepair - repair GIS polygons
SYNOPSIS
prepair [--wkt string | -f file | --ogr file] [--robustness] [--minarea AREA] [--isr
GRIDSIZE] [--time] [--shpOut]
DESCRIPTION
prepair permits you to easily repair "broken" GIS polygons, and that according to the
international standards ISO 19107. In brief, given a polygon stored in WKT, it
automatically repairs it and gives you back a valid WKT. Automated repair methods can be
considered as interpreting ambiguous or ill-defined polygons and giving a coherent and
clearly defined output.
OPTIONS
--wkt 'POLYGON(0 0, 1 0, 1 1, 0 0)'
Process polygon from WKT string
-f infile.txt
Process polygon from WKT string on the first line of the file
--ogr infile.shp
Process first polygon of the input file
--robustness
Compute the robustness of the input/output
--setdiff
Uses the point set topology paradigm (default: odd-even paradigm)
--minarea AREA
Only output polygons larger than AREA
--isr GRIDSIZE
Snap round the input before repairing
--time Benchmark the different stages of the process
--shpOut
Output a shapefile (out.shp) instead of a WKT
Use prepair online using onworks.net services
