High order GVG edges in High order Generalized Voronoi Graph ( HGVG ) are introduced to solve this problem .

为此采用高阶广义Voronoi图（HGVG）中的高阶GVG边以解决连通性问题。

The GVG system is a new solution , with the conception of sampling lineage instead of the traditional sampling point or sampling area , to extracting crop acreage information .

线采样系统提出以线状样区代替以往成数抽样中的点样区与面积样区概念，通过统计线状样区内作物种植面积成数来反映区域总体农作物种植面积成数。

The incremental construction procedure in this paper can be extended into three-dimensional spaces , and the base component of the map system is generalized Voronoi graph ( GVG ) in three-dimensional .

此外，本文的增量式构造方法扩展到用于三维空间，此时地图的基本构成为三维空间中的广义Voronoi图（GVG）。
