摘　　要：为了充分提升GIS地图矢量化成果的可用性,开发一种全新的地图制图数据组织模型,在不使用任何机器学习算法的原则下,使用过程完全可控的矢量化生成矢量地图。该模型矢量化成果中完全避免了样条曲线的生成,全部使用直线、圆弧、单点矢量模型实现GIS地图的矢量化。仿真测试验证中,该模型的反算重合度略低于2019年普及的Supermap GIS系统,但其他客观数据表现和用户主观评价显著高于Supermap GIS系统。最终认为该模型可为新一代GIS地图矢量化处理模型提供参考。In order to fully improve the availability of GIS map vectorization results,a new map data organization model is developed.Under the principle of not using any machine learning algorithm,vector map is generated by vectorization with completely controllable process.In the vectorization results of the model,the generation of spline curve is completely avoided,and all line,arc and single point vector models are used to realize the vectorization of GIS map.In the simulation test verification,the back calculation coincidence degree of the model is slightly lower than that of the SuperMap GIS system popularized in 2019,but other objective data performance and user subjective evaluation are significantly higher than that of the SuperMap GIS system.Finally,it is considered that the model can be used as a new generation of GIS map vectorization processing model.
