Convert Voronoi diagram to shape file

2 views (last 30 days)
Hi,
I need to convert a voronoi diagram into a shapefile to plot it in Google Earth.
Currently my code looks like this:
X=[-74055915;-74068052;-74101923;-74060203;-74091317;-74089282;-74114873;-74071424;-74074763;-74105454];
Y=[4694567;4630518;4623200;4668864;4696542;4617255;4576684;4611062;4720726;4656747];
figure (1)
Polvor= voronoi(X,Y)
Thanks for your help

Hi,
To convert a Voronoi diagram into a shapefile and plot it in Google Earth, follow these steps:
  1. Generate Voronoi Diagram: Use MATLAB to generate the Voronoi diagram with your X and Y coordinates.
  2. Extract Voronoi Vertices and Regions: Use MATLAB's "voronoin" function to get the vertices and regions of the Voronoi diagram. Check out: https://www.mathworks.com/help/matlab/ref/voronoin.html
  3. Create Polygons: Loop through the Voronoi regions to construct polygons.
  4. Create Shapefile: Use MATLAB's "shapewrite" function to create a shapefile from the polygons.
  5. Convert Shapefile to KML: Use a tool like GDAL's "ogr2ogr" to convert the shapefile to KML format.
  6. Load in Google Earth: Open the KML file in Google Earth to view your Voronoi diagram.
Hope it helps.
