I created a voronoi polygon using the coordinates shapefile of over 3,000 enumeration areas. How do I get the boundary coordinates of each of the enumeration areas for mapping purposes?

    Welcome to GIS SE, please expand more what you mean by "boundary coordinates", is this the bounding xy min/max or the xy vertex coordinates? – artwork21 Apr 13 '18 at 12:47
  • the boundary coordinates are meant to guide mappers so that they dont encroach into another enumeration area. so I need like the coordinates for the four corners of each of the polygons – user118372 Apr 13 '18 at 12:53

Vector -> Geometry Tools -> Extract Nodes

then

Vector -> Geometry Tools -> Add Geometry Column

gives you for each corner node of your polgyons and then adds it's coordinates to your attribute table.

  • i have already done that but what i actually need is the coordinates for each of the polygons generated not for the points. – user118372 Apr 13 '18 at 13:00
  • As I said, leave out the polygon centroid step, but the coordinates obtained are confusing as in you get one coordinate for every corner of your polygon. Oh, forgot a step, I am sorry... updated the post – Erik Apr 13 '18 at 13:42
  • i left out the polygon centroid step – user118372 Apr 13 '18 at 13:46
  • I actually forgot a step, sorry for that. So, now the post is (hopefully) helpful. – Erik Apr 13 '18 at 13:48
  • ok, please i am waiting for the post. – user118372 Apr 13 '18 at 14:00

just use OGRINFO so simple. ogrinfo -ro -so nameoffile.shp nameoffile convert a folder of shapefiles into a GeoPackage OGR2OGR -f "GPKG" name.gpkg folderofshp
