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
- FC--wktF[0] 'POLYGON(0 0, 1 0, 1 1, 0 0)'
-
Process polygon from WKT string
- FC-fF[0] infile.txt
-
Process polygon from WKT string on the first line of the file
- FC--ogrF[0] infile.shp
-
Process first polygon of the input file
- FC--robustnessF[0]
-
Compute the robustness of the input/output
- FC--setdiffF[0]
-
Uses the point set topology paradigm (default: odd-even paradigm)
- FC--minareaF[0] AREA
-
Only output polygons larger than AREA
- FC--isrF[0] GRIDSIZE
-
Snap round the input before repairing
- FC--timeF[0]
-
Benchmark the different stages of the process
- FC--shpOutF[0]
-
Output a shapefile (FCout.shpF[0]) instead of a WKT
