Hi,
I want to creat a KML file with polygons containing holes. The starting data was a raster, then a SpatialGridDataframe. I finally transformed it to SpatialPolygonsDataframe with Grid2Polygons() (with several levels).
Then a creat KML file with plot KML.
The problem is : the polygons with holes are not correctly shown in GE. There are some small polygons that are hidden under larger polygons and so on..
Thanks for your helps
