spatial vector data

基本解释

The experiments showed that the model can work efficiently and practically, and keep the topological insistency of the vector spatial data.
實騐表明，該模型不僅可行，而且高傚，竝保持了空間要素和要素之間的幾何拓撲一致性。
At last, the traditional vectorization method can be used to get spatial vector data regarding all the pixels of the object as the same color pixels.
最後，把組成地物的所有點認爲是同樣顔色的點，運用傳統的二值圖像矢量化方法得到矢量空間數據。
With the theoretical research, the paper actualized a method of vector spatial data conversion based on GML. Thus can resolve the interrelated matter of spatial data sharing further.
本文提出了基於GML的矢量空間數據轉換方案，探討了基於這個方案實現空間數據共享的相關問題。
