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 stan‐
       dards 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 poly‐
       gons 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
