示例1: clusterizeGeometry

import com.vividsolutions.jts.geom.Point; //導入方法依賴的package包/類
private static Geometry clusterizeGeometry(final Geometry geometry,
      final double distance_ratio)
{
   if (geometry == null)
   {
      return null;
   }

   int number_geometries = geometry.getNumGeometries();

   if (number_geometries > 1)
   {
      Geometry [] clustered_geometries =
         new Geometry [number_geometries];

      for (int igeom=0; igeom<number_geometries-1; igeom++)
      {
         Geometry current_geometry = geometry.getGeometryN(igeom);
         Point current_centroid = current_geometry.getCentroid();

         if ((current_geometry == null) ||
             (current_centroid == null))
         {
            // TODO Warning

   else
