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.
实验表明，该模型不仅可行，而且高效，并保持了空间要素和要素之间的几何拓扑一致性。
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.
最后，把组成地物的所有点认为是同样颜色的点，运用传统的二值图像矢量化方法得到矢量空间数据。
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.
本文提出了基于GML的矢量空间数据转换方案，探讨了基于这个方案实现空间数据共享的相关问题。
